I did the maths at home with a nice spreadsheet. Initial investment in LEDs is a lot to do upfront but they pay for themselves in about a year. It's a no brainer nowadays. You'd be stupid to choose a anything over LEDs

Christopher DuVall I work from home, and my 6 Hue LEDs generate a lot of heat. Not as much as the old ones, but enough to make me sweat if it's on for a while
Aji Setiawan I hope for heatless or at least lukewarm lights in the future. Even the newest LEDs, smart or not, get pretty hot after a while. Makes the AC work harder in summer
Would have been nice if the reporter (who was great otherwise) actually quantified the life span. Rough rule of thumb in the UK. LED lasts 10 times longer. At 2 the price it's still kind of a no brained.
If your house is efficient and your country produces energy with renewables and nuclear, waste heat is no problem. Old style bulbs are dead easy to manufacture, and the waste heat is just load of central heating.
I had a lot of incandescent bulbs that I threw away recently. They were bought back before the price of LED's became reasonable. I want to save money, and help the environment.
@@vids595 There are specific LED bulbs designed to be used for dimmers, but not all dimmers work as well. Current price for 60W equivalents is about $2 when bought in bulk, so they are no longer anywhere near 25x the initial purchase price. Life is MUCH longer than incandescents provided you don't let them get too hot, but they may well fail early if you try to run some non dimmable bulbs on a dimmer- you need special bulbs, they're a bit more expensive than $2, but still nothing like 25x.

A thing to note is that LEDS are also incredibly adaptable in form factor. There's a bajillion ways to arrange those diodes. So much so that there are LEDs which mimic the old Edison filament bulbs using tiny strings of LEDs. They look amazing
Is there a good replacement for tube tungsten bulbs such as the T3 format? I can only find ones that are large corn cob shaped that don't fit existing fixtures.
yep. we've swapped out all our incandescent bulbs as of a few years ago but just recently in the last 6 months, I've been replacing the decorative bulbs with the clear LED edison style bulbs. They are just as, if not brighter, than the incandescent/CFL bulbs, just as cheap and I have not had a single LED bulb fail since I started installing them. And now, the smart RGB LED bulbs are dirt cheap too. The HUE bulbs (still expensive) used to be one of the only options but I have installed about 4 smart bulbs now and paid maybe $8 per bulb and work really well with Alexa. It's let us set smarter timers (like automatically turning them on with a slow progressive brightness increase in the mornings to wake us and the kids up) as well as soften the rooms at night with less bright and warmer color lights or change colors if we're watching a movie. I thought they would be a gimmick but I really like them and when we have guests over, not only are they really impressed with how neat the room can look but also at how inexpensive they were and how much you can do with them.
Life Hack! you can buy LED bulbs at "Dollar Tree" for $1. My whole house is LED now, also you can buy them online, even less then $1. At this point there is no issue because the cheap LED bulbs are basically the same price as incandescent and getting cheaper, and the bulbs last 5 times as long and 5 times cheaper energy cost, its not the end of the world, people are naturally converting to LED without needing to force them.
@@someguy2135 - Forcing manufacturers to compete on price with incandescent bulbs is what drove down the prices. Some people have commented that their government subsidizes the cost of LED bulbs, but that just means that they are paying a LOT more for them, because we all know that companies never lower their prices for government purchases. Any time that a third-party payer is involved, the actual cost is increased at least 40%. Ask them what their tax rates look like, how much of their paycheck they get to keep, and what their cost of living is like.
@@SaysEveryone The price of bulbs is not a problem here in the USA. They are cheap. The problem is climate change which incandescent bulbs make worse compared to LED's and even CFL's. Trump's policy increases the chance that incandescent bulbs will stick around.
Speaking on a personal basis, I can state that our household (in the UK) started switching over to high efficiency lamps during the 1990s. Because these lamps tend to last for a very long time, we have accrued a box full of spares. The spare lamps had been in a box for so long that I had forgotten that they were there, and had needlessly purchased a replacement in 2018 when one had failed.
Bulbs? I am from Serbia (European country, less developed than US, average salaries around 400-450$), and i installed LED light stripes to whole house. Investment cost around 100$, and after 3 year not the one light point died (or how you call them). Everyone of thousands of them work until now. Electrical bill is lower, light in house is lot better. I even convince my family to do same in their house, and they are very pleased with result. Bulbs are past. LED lights stripes are future. Maybe i will install new one. I seen many great ideas what I could do with them on YT.

As a student, I swap out the bulbs in the place I stay, if I have to pay for power, with LEDs, and swap them again when I leave, they’ll last around 10years, no way imma let my land lord keep em.
In the UK, rented homes have to reach a minimum energy efficiency level, it gets inspected once a decade for things like insulation, efficient appliances etc... When I moved in the house was full of incandescent bulbs, I replaced them with LED bulbs. Later when the inspector came he gave the home extra points for having all-LED bulbs. This meant the landlord wasn't legally required to install any insulation (to the uninsulated house) as it exceeded the minimum standard... I'm just pissed I didn't put the landlord's own bulbs back in before the inspector came... That way he'd probably have had to install insulation and I'd be warmer and pay less for heating.
Oscar vL Generally the deposit doesn’t begin to cover the amount of damage. And if I tried to charge them a big enough deposit they wouldn’t rent from me. That’s just the way it is. At least where I live.

As a lighting engineer, this video oversimplifies some things about lighting technology, especially the lighting spectra. Just in the past 2 or so years, we have been able to make LEDs that come quite close to the spectrum of sunlight (e.g. Nichia Optisolis, Bridgelux Thrive, Seoul Semiconductor Sunlike-although none are widely available in finished products yet), much closer than the typical "blue spike" spectrum shown in the video. We are also able to cut down blue for evening applications (e.g. in my product, Bedtime Bulb) to reduce circadian rhythm disruption from blue light. Nevertheless, this video is very helpful for understanding the context of the rapid shift toward LED, and the rollback of the "incandescent ban."

It allows companies to promote more bulbs... Which needs to be replaced more often... Thus, more profits for them... Thats why they didn't promote CFLs for 25 years since their innovation
HAD to buy LEDs - not happy. Quality of light inferior for my purposes, and have to run the heater more to compensate for heat not generated by the lights. Saving ZERO money on power. Just lost the right to chose what type of bulb works for my application.
To me regulations do not matter, I will choose a more efficient and cheaper to run source of light, I used to use CFL and now I use LED, 100% of my house is LED lit.
Good story, but misguided on LEDs being too expensive for poor people. Here in California, one can buy high quality CRI > 90 LEDs at the 99 Cent Store or Dollar Tree. Our electric company, So Cal Edison subsidizes these (says right on the box). I've tested them against my $17 Costco bulbs (no joke), and the light quality is just the same.
There's that magic word: "subsidize." Just like I get to subsidize my neighbor's solar panels by paying the highest rates for his electricity and he gets very generous tax writeoffs for his rooftop array, which I also pay for. He gets all of the advantages, I get the bill. Government in action. Who exactly is misguided here?
@@demef758 Obviously you are the misguided one. Why aren't you taking advantage of lower energy bills? You are whining about spending more money while not doing anything yourself to improve your situation. Are you one of these people who pay more for lower quality for the sake of tribal identification? Power companies actually like residential customers to use less power. It reduces their overhead costs for their most regulated ratepayers. BTW, "Tax what you don't want. Don't tax what you do want" is a basic libertarian principle.
I think this is becoming the norm rather than a consequence of subsidies. LED bulbs have gotten so incredibly cheap. They sell them in Poundland (UK dollar store) without any subsidies for £1 ($1.31). Like all technology, when it goes mainstream it becomes affordable to the masses.
Wait what, the USA still sells incandescent lightbulbs? It has been forbidden in Brazil since ... well I can't remember, even the poorest uses CFL lightbulbs, it's rare to see incandescent lightbulbs, people really care about having low energy bills, or bright if they are stealing energy...
GBA811 it doesn’t help power is so cheap here. A kilowatt hour in northeast Brazil is around 50 cents here it’s around 10 cents or so depending where you live. Unfortunately this means people care less about how much power they use. Especially the ones who are so adamant about keeping things the way they are. They don’t care the new bulbs use less energy they just want what they are used to. I used to work at a grocery store and this older guy was super upset that we didn’t sell incandescent bulbs anymore.
Unlawful_Falafel oh yea for sure and I went to the Dollar Tree and picked up LED bulbs for $1 each. The older bulbs are terrible, sure the light they put out is nice, but at the expense of heat, terrible waste of power, and potential to burn yourself and the environment around you. Easy Bake ovens were just little incandescent bulbs in a small box lol.
Doug Wiser try heat with absolutely no central cooling. Even though I’m from there originally I always hated the heat. You get used to it a little but still it’s unbearable at some points. At least in the US you have climate controlled environments. Also this is northeast Brazil south Brazil gets cold and you have the opposite problem, no central heating.

There are warmer CFLs that are more incandescent. I appreciated the spectral distribution curves and loved it was more technical but also should've mentioned CRI and color temperature. Also most LEDs don't get a warmer color as you dim as an incandescent bulb would.
@C.J. Tymczak I'm using dimmable LEDs already and I can control them with my phone. The slightly more expensive model allows the user to change the color temperature as well, but I didn't need this since I prefer warm light in all situations.
2700k dimmable leds are not the same as incandescent filament lights in terms of performance. Leds are brighter per watt but tend to produce a stroboscopic effect which becomes more pronounced as the light dims down due to having to rely on pulse width modulation not amperage modulation. Also true 2700k leds use blue gallium nitride leds coated with a yellow tint film to present as 2700k so they look more like a blue light source and a yellow light source mixed together. Im not saying that incandescent is better for all applications but that it does have its area of best use. I am also stating that leds are not perfect for all applications either but are best suited to their specific enviroment. In conclusion as with everything the correct tool for the correct job is important.
How about your appliance bulbs? I had a Sense monitor installed when I got my solar system and my fridge has 3 40W incans and freezer has 1. 120W spike every time the fridge was opened. Now I have 4W LED appliance bulbs inside, and the lighting is much better and brighter!
Kind of an orange color. GE called them the golden glow. Low Pressure Sodium lamps are the Yellow ones. VERY Yellow. You should look into that before you stick with your assessment.
Ah yes, that's indeed a must-have for the warmth of the color, I hate the fact they are hard to find on DIY stores here, generally you end up with tinted halogens.
One thing that's worth noting is that not all LED bulbs have a high CRI. However, most of the bulbs you'll find in stores nowadays have pretty good CRI, and you can easily look for really good ones if you need that, since most have it printed on the side of the box.
Although almost all of the lights in my home have been replaced by CFLs or LEDs, I still keep and use some incandescent light bulbs. They're warm, the color is pleasing, especially suitable for reading in cold winter days. And its color rendering index is unbeatable. Incandescent lights will always be with us, for they still have some special use cases, but they won't be mainstream any more. We really don't need to worry too much about what kind of light bulbs we use, for keeping the lights off when you're away makes a bigger difference. 🤔
Simply speaking, No. Just just....no. Please just no. I shouldn't been having to explain myself about this in almost 2020 but here we are.

My house still has incandescent bulbs because theyre not burning out. They're so old but somehow they're still kicking. We don't buy then anymore though so they'll get replaced eventually.
If it's cold, then the extra heat that incandescents provide is nice sometimes. The quality of incandescent light is also the most 'flattering' to the human skin colour.
The price factor argument is wrong. If you go to Walmart a 4 pack of led 60 watt equivalents are about 1$ a 4 pack of incandescent 60 watt bulbs are almost 4$.
That's not true here in Ky. Just bought lightbulbs a couple days ago, it was $8 for a 4 pack of LEDs and $2 for a two pack of incandescent. I just checked Walmart's website though, and they are cheaper online, and they don't even have the same incandescents listed, and they have to be shipped to store, so I'm assuming they're just selling their remaining stock.
Jake Steel, remember in this video they pointed out that only in *impoverished* neighborhoods in the US are the retailers selling LED bulbs at higher prices than elsewhere in the country. This is called price-gouging and is intended to exploit the poor who often don't have internet access and can't travel that far to go to a wealthier neighborhood to buy fairly-priced LED bulbs. These unethical retailers know that the less-privileged citizens in their area can't afford to travel far from home and only have access to their store and also know that most of these shoppers will *want* to buy LED bulbs to save money on energy bills in the long-term since they are impoverished, so the retailers set ridiculously high prices on the more-desirable LED bulbs since their customers have no option to shop elsewhere.
@@lasarith2 I'm sorry if wasn't very clear, I can understand that to people living in the UK it might make sense to buy leds with this price, what I meant is that to most of us in the rest of the world £3 is a considerably large amout of money to pay in a lamp, due to exchange rates this is 5 times more than I would pay in an LED
The nature of LEDs means they can be adjusted to give any colour in reason. The notion LEDs are bluer (or colder, the normal parlance) is actually not true, outdated and far truer of cfls. In fact modern LEDs are pushed to give full spectrum at lower intensity for colour fidelity and boosted at lower frequencies to give a warmer (redder) tone closer to the incandescent people love. Higher frequency bluer light leds are actually harder to produce and less energy efficient. The equal tone LEDs that were more popular to begin with may appear bluer on account they would treat all frequencies equally but truthfully they all lean red as lower frequencies being lower in energy have greater intensity or luminosity at equal tone.
One thing I like Is that they've gotten energy efficient enough to handle them whilst on without being burned. Can remember you couldn't do that several years back.
If you live in a part of the country where it is below freezing, an incandescent bulb is a really good source of heat. It is expensive heat compared to natural gas heating, but it does add heat to the house. In the winter when the temperatures would drop to sub-zero levels (below 0 F, -18C) my grandmother used to put a lit 100 Watt light bulb under her car's hood to heat up the engine and a large blanket over the front grill to keep the heat from flowing out the front, and it worked, it kept the engine warm so it had no problem starting in the morning (now we have synthetic oil to avoid that problem). If you have areas of the house that have a light that gets turned on, then off a few seconds later (like a closet), then a simple incandescent bulb is all you really need. If you have an OVEN, and it has a light in it, you need to use an incandescent bulb there as anything else will melt in the heat. But generally, in almost every spot in the house, it better put an LED lamp there to save on electricity costs.
When I bought my house 13 years ago, I ran out and purchased CFLs and replaced every light in the house. Worst decision I ever made! The quality of the light was horrible! The big problem was the constant flicker. I have eyesight problems and I found the CFLs to be impossible to read with and found the light tiring (they bothered my nystagmus). Within a year, at least half of them had been disposed of and I swore I would never use anything but incandescents again. With LED lights, I have taken a more cautious approach. I find them glaring, even in the warm white that I usually buy. There is a noticeable flicker, but not nearly as bad as the CFL bulbs. I have about 85% of my lights replaced with LEDs now, and the other 15% may never be replaced. Most if not all of them are in places where I care about the quality of the light. This includes my bedside reading lights (used around 30 minutes per day), the chandelier in my dining room (used probably 2 hours a week), my bathroom lights (it is hard to shave with the flicker), and my Christmas lights (used 5 hours a day, for three weeks each year). None of the lights that I intend to keep incandescent are used heavily, most are low wattage and I am happy that President Trump gave me the option of deciding what is is the best for me. Oh, and here in Ohio the worst use for LED lights is in stop lights! The LEDs don't melt the ice and snow so the stop light is often not visible! The best use for LED lights: closets! They are less likely to start a fire, but as little as closet lights get turned on, you will never save money here!
I appreciate your incredibly thoughtful approach to your home lighting. However trump did nothing to protect you from having to switch away from incandescent. The federal government was never planning on banning incandescent. So I am not sure why such a thoughtful person watched this video but still agrees with the rollback of these new regulations. The law passing had a direct effect on the amount of lighting options you have for your home. The issue isn't that people will only have one type of lighting to choose from, the issue is that unless regulations help the majority of consumers to switch to more efficient bulbs, everyone loses money, and everyone loses efficiency. So money and power being lost. More fossil fuels burned, etc. It just does not make any sense. Unless the regulatory rollback is designed to please your lobbyists and voter base. In which case mission accomplished.
President Trump's rollback of the regulations increased the options available for consumers by including incandescent bulbs as an option. The specific bulbs that would not be available are "specialty bulbs" which would include those for my dining room chandelier, reading lights. Because of this rollback, I have the ability to continue buying these bulbs as incandescents. LED bulbs are available today for these fixtures. I choose not to use them. My buying options have increased. Once again, the majority of my lights are LED including all of the high wattage bulbs. It is only where quality of light is paramount that I have retained incandescents. I did purchase a stash of 60 watt bulbs right before they stopped selling incandescents. The stash is untouched as I have never needed (or wanted) them.
Wow finally a smart intuitive man different from the 99.9999 drones who just follow the trends. My bedroom and bathroom have incandescents while my outdoor lighting is cfl/led. The verge is being disingenuous with its one sided info.
the narration sounds like a high school student reading their report in front of the class. It's amateurish and poorly delivered with uptalk and non-sequitur statements.
Halogens? What about sodium lamps and mercury lamps? There are a lot of types, we just have no idea which one is the "best" yet. LEDs are great, but for whatever reason, some people might prefer a different type due to the very specific way it produces that light. Something like that. :/
Although consigned to nightlights there is also gas discharge (neon) and Electroluminescent. I read about plans to make Cathode Ray Tube Lights (or something that uses that principle. Radiowaves??) but nothing seems to have come of it. LEDs may have improved too much to make it practical.
Edison invented the first practical, commercially viable light bulb. Let me guess, you hate America, right? Just to pile on, an American invented the LED bulb, too.
Edison invented first light bulb but he was like S. JOBS took other people ideas, then developed his own version of that product and credited himself. If someone tried to step in front of him he would get rid of them like he did with N.Tesla
One of the great options with LEDs is that you can buy them in strips for lighting in lines rather than point sources. This works great for kitchens, shops, and even under counter and shelf lighting. It giver a nice source of almost omnidirectional light, and is great for standalone solar lications where energy efficiency is important. I know this probably sounds like an ad, but we tried a few strips here, and they really helped. I'm going to try them in every room.

Just a little oversight.
Feels like this was made 10 years ago. In Europe this isn't a discussion anymore, and CFLs aren't used anymore, and incandescents were banned some years ago.
I was a lighting engineer. LEDs that last forever where developed 30 years ago. The industry soon realised this technology would render their industry redundant in a few short years, so it seems they have removed this technology from the market.
The very first Philips LEDs last forever, I have a bunch of the early LED bulbs with the three yellow lenses for the LEDs and not one has failed, there are still use cases for the long lasting LEDs but mainly in niche cases like GM check engine lights or Lindhaus bag/clog indicators
It amazes me how people even in the end of 2019 still don't understand that CFL phosphors have actually been able to be further engineered to produce more color types. She was using a cooler CCT CFL and criticizing its 3500+K color temperature as if all CFLs looked like that. BS. Even in the past, phosphors were developed to allow for CFLs to put out soft white light much like an incandescent bulb
Incandescent bulbs are fashion pieces. CFL bulbs are overall inferior. I'll never use CFL bulbs again. All the lights in my house are led strips and bulbs. Much better for the budget and getting cheaper all the time. The led bulbs are a one time buy. Led bulbs seem to last forever, I've never replaced one. When something better comes along I'll try that solution too. The data provided showing correlation between low wage areas to high priced led bulbs is disturbing.

As a 20+ yrs electrician you would be shocked and not amazed. The price of light bulbs are based on demand and production. So the old incandescent bulbs went way up, and the cfl and LED bulbs started off pricey but never came down. The giant turbines at our hydroelectric dam were retrofitted finally after decades and we're made almost %100 more efficient doubling it's output. The money they spend to maintain the system costs alot but the electricity is essentially free, and out if all the money they take in from customers they make an absurd amount of money. The dams they built flooded valley's which they announced they were bringing cheap electricity to the masses, but their rates go up every year. It's sad how such greed could perpetuate such a sham and be able to keep the public unaware.
@@databanks those aren’t installed in “US homes” I think the 44% “incandescent” figure doesn’t include halogen (which, despite being uncommon by count, are very popular for higher-power lighting, thus contributing a disproportionate amount here) Also don’t forget fluorescent tubes - which aren’t CFLs
You can't use most LED lights with dimmers. You need to add a filament lamp so there is sufficient current draw to trigger the dimmer circuit. Also, LED lamps are being made with such cheap regulator circuitry that they will flicker on their own at mains frequency. They also tend to be over driven to put out more light which reduces the lifespan dramatically unless you lower the input voltage by using a dimmer circuit. Oh, wait, you can't because it will flicker.
The scam on the led bulb was it's going to use less electricity and save money It does use less electricity and saved money on your power bill Until the power company jacked up your rates the 23% you were supposed to save 5 years later Thanks power company's your so thoughtful
i use led everywhere, but have some old lightbulbs lying around to screw into my desklamp if i want to take nice pictures since in my experience leds still usually dont outperform incandescent bulbs another benefit is that u can point incandescent bulbs at ur body and u get a nice warm spot similar to outdoor infrared heaters
I was in the lighting game for several years back in the late 1990’s, and yes - LEDs are the best answer nowadays. Like CFL lamps though, we ought to consider the full life cycle costs. The end-to-end materials and fabrication costs and energy footprint are important.
LED lightbulbs are available at the dollar tree, for $1 per bulb. Super cheap, easy, and you even have the option of daylight bulbs as well. Absolutely no reason to use anything else considering the cost.
One can still buy incandescent in EU, it's just that they're not popular anymore, since only small shops sell them "for industrial lighting only". Reality is that led and fluorescent are way more expensive initially, though in the long run are definitely cheaper because of the lower energy they require.
Need an argument? Put your hand on a 100 W LED equivalent bulb. Now do the same with an incandescent... The LED is a lot safer for children and pets... Convinced my wife!
Smart color LEDs are programmable, dimmable and can have any of 16 million colors. That's more romantic and more efficient than incandescents. Yeah, they cost more but they are still infinitely more versatile and romantic.
@@arturduchene Do not use those color change RGB bubs for general illumination, they have horrible color rendering. You often can't distinguish orange from red, cyan from blue, pink from purple, etc. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-5U-F7EhLp7g.html
I bought one of their led bulb made by the company that owns dollartree. Didn't last 2 months. Would sit there and flash trying to turn on. The ones they sell by Sunbeam have no problems with so far.
Energy use or efficiency is a red herring, what the government really wants is more Tungsten for it's space weapons programs. Tungsten is used as the filament in incandescent bulbs and it's a relatively rare metal that can only be obtained through lots of mining. But because it has the highest melting point of any metal, tungsten rods can survive re-entry intact; the newly commissioned space force wants to use the Tungsten to create kinetic energy weapons that are dropped from orbit and then descend onto military targets on the ground. The only catch is that, these "Rods from God" need to be of sufficient size to inflict the damage they want to, think of a projectile the size of a telephone pole made of solid tungsten. That's equivalent to the amount of tungsten in a whole lot of incandescent light bulbs.
Incandescent has its upsides: 1. Days are shorter during the colder season, thus more in need of artificial light. Since homes need heating during said season, the "waste" heat produced by incandescent bulbs isn't really wasted, but it simply contributes to heating the home, lowering HVAC consumption. All the while, the same can't be said for streetlights: but they never used incandescent anyways. 2. Incandescent bulbs are much cheaper to manufacture when compared to LEDs. 3. Correct waste management of LEDs is much harder than incandescent.
NITHYANANDAN S Nobody outside the US thinks it's the fastest developing nation! It's either a joke, going backwards, or a terrifying threat to the planet, depending on your point of view.
People in less affluent communities needs to sit down with a piece of paper and a pencil (costs $0.99 at a dollar store) and do the ARITHMETIC (its NOT EVEN MATH)... Step 1: Calculate how many light bulbs you have in your house and which ones you use MOST... Step 2: Take the number of bulbs you use MOST and calculate the cost of purchasing these bulbs per year. Step 3: Calculate the cost of powering those MOST used bulbs per month and per year (number of hours used per day X number of bulbs X their WATTAGE, which is written on the bulb X how much you per for your electricity, $/kWh) Step 4: After you have all those numbers, calculate how much money you can save by replacing those MOST used bulbs with LED Bulbs --- HYPOTHESIS: You can afford to switch within a month or 2 and start saving money RIGHT AWAY... simple stuff Oh one more thing... DO NOT BUY LED BULBS from the like of LOWES/HOMEDEPOT... you can get much better price online from Amazon and such...
I remember being in high school math class and graphing trends of energy use versus upfront cost of light bulbs. The other option was halogen instead of LED. We compared incandescent, CFL, and halogen. LED existed, but it was very expensive.
The problem I'm facing are all the old first gen LED bulbs I have around my house. They don't work well with dimmers, have a terrible CRI and light distribution patterns, yet they just refuse to burn out. I'm anxious to replace them with some nice modern warm glow dimmable LEDs that got incredibly cheap lately, but can't convince myself to throw the old ones away. CFLs were advertised to have a similarly ridiculous long usage life, yet almost all them have failed over 10 years or so, not the case with LEDs.
CFLs had the on/off issue. If it doesn't have a built in delay, it'll burn out really quickly. Also, the burn in issue where it would get so much darker over time. LEDs are awesome. The EU's energy efficiency ratings are awesome too. Even a D rating almost guarantees the bulb will last forreeeeever.
people shouldnt be forced to use a specific product, that product should be their choice to use because it costs less. Or like with incandescent, use it because it helps heat your home during a cold winter. And also i've had CFLs burst into flames, scary.
Important to note that, in warmer climates where air conditioning is routinely used, incandescent bulbs bite your energy budget twice, since not only do they use more power per unit of useful light, but also because every watt consumed ultimately becomes heat which you must then pay to remove via air conditioning in order to to maintain a comfortable ambient temperature.
LED bulbs have their drawbacks. The light output causes sleep deprivation. Had to go to the doctor recently. Problem......I was only sleeping 3 hours a day. Asked if I had LED lighting, used iPads and an iPhone. Yes to all. He said stay away from LED lighting.
I ditched all my incandescents over 30 years ago for compact fluorescents. The electric utility was practically giving them away at the time. As those fail I replace them with LED, but some of the cheap ones have failed within months due to driver failure. Look for LED bulbs with prominent heat sink fins.
No bulbs have fins nowadays as LED chips become more efficient, look for those that says can be used in totally enclosed luminaires as they generate less heat and require little cooling.
@@daijoubu4529 Actually, the bulbs still need fins but no manufacturer puts them there anymore because its too expensive and makes the bulbs last too long.
In Australia the state governments subsidised the replacement of incandescent bulbs with energy saving ones. They had energy companies visit your home to do the replacements with the best suited bulbs.
