Dodgy CFL-style LED in a funny box 

These guys solved my issue, I was dubious about installing LEDs or CFLs, then this guys said "why not both?" And created this amazing product. It's so good that I used it in my hotels and my hotel. 11/10

"Can adapt to China's actual situation" Actual situation : voltage fluctuates from 86 to 265 volts?! ...... Got me dead💀😆

You should do a collaboration with Big Clive on Chinglish writing on Chinese electronic products, it would be hilarious!!!! Great tear down as always DGW.

A calculator with no numbers on the keys, that's an interesting concept. Add's an element of surprise into math. Nice!

Dodgy circuit, hilarious box and great circuit explanation. Enjoyed thoroughly haha

I can't stop my laugh while reading lamp descriptions on packing box! LoL. Thanks for tearing down electronic with sense of humor. Not only giving knowledge but also entertaining!

these where popular in denmark too!! in my home we didnt change light bulbs from 2009 to 2017 (so basically all regular CFL until then) but my grandpa had bought some of these CFL looking LED bulbs and my uncle as well had them in the driveway street lamps around 2012 :)

At first, I thought using the CFL glass tube was a clever way of reusing old stock of that twisty glass... then I realized that, well... I'm not sure it would work that way, not without modification to the glass. Right? Also, the LEDs would probably be getting fried with no airflow or way to cool properly. What a weird lamp!

Nice! Even in Australia where in theory are strict conformity laws we see such items. You could glue them 2 strips under a shelf and make a traditional isolated supply. I bought fluoro substitutes from very reputable supplies but the inverters still die shortly out of warranty. We live in a throw away world!

LEAVE THE CALCULATOR INTACT!! Thats a working relic of the past and they all eventually go bad. please keep it good! That machine is a thing of beauty, a historical masterpiece!

aww, I've missed that level of comedic english on product packaging. now it seems like most chinese manufacturers have managed to hire someone competent to write what goes on the box, but this is a return to the glory days of 10 years ago when you were almost guaranteed this level of entertainment with every ebay purchase. the actual lamp too has that same flavour, super budget-cut, weird old-stock cfl housing and badly made buck board.

Yes, i'm calculating on you to open that calculator! Thanks for the presentation of this indispensable CFL-style LED lamp, oh the ideas that pop up in some peoples heads!

A most enjoyable video both from the point of view of the printed text on the box, and the circuit analysis.

I spent the last week binge watching your videos. Just wanted to say thanks for the great, varied and interesting content.

Maybe the label is made in the EU and the lamp in China 😁

8:05 Well, it's very warm, the capacitor needs cool air on its legs! lol 😂😂Thanks DGW, another great video!! God bless you! 🙏

You need to make a few videos on computer DVD drives. They are a true goldmine of technology-brushless motors, brushed motors, magnets, lasers, nylon gears, stainless steel axles, PCB's with golden components like voltage regulators, motor drivers, memory chips cpu chips, headphone amp driver chips, indicator leds, potentiometers and more. I think you could trully make a 30 part series on reusing these machines of peak capitalist material abundance.

Thanks for my daily laugh, especially when you 'got stuck in' with the screwdriver. I kind of like the look of this lamp - definitely not seen at my shops in Australia although I would be tempted to replace the regulator.

Please never stop making videos! You are great!

Aside from the power supply and box issues, the method of using LEDs on an aluminium strip seems quite an interesting construction

Another great video, thanks for the tip about the extra bit of winding on the transformer

The cat is waiting for a bath in the basin.

The demonstration is much more funny!! This made my day!!! 😍😝

Hilarious spelling on the box and a dodgy circuit wow! Great video i love these dodgy products and seeing how they have been made to be as cheap as possible

I think you'd be the best quality control, leader. Since you always dive into circuit boards and take them apart, it is by far the best videos from you.

very minor detail, but if anyone was wondering, the circle instead of a . is because there is . in chinese, they use the circle

I like it, mainly for the size and simplicity. It has enough surface area to keep the LEDs from early failure and is priced cheap enough that one can almost forgive the flaws.

Tak koukám, že obě věci v pořádku dorazily, to je super :) Cena byla vskutku 59Kč, ale dva roky nazpět, co jsem ji koupil. Teď jsem už nekoukal, jestli to tam ještě mají a kolik za to chtějí :D

I'd try this one on a variac to really see if it accepts "china power grid situation"

I actually like how these lamps look. I was tempted to buy one (with U shaped tubes) some years ago (the only time I saw them where I live), but the high price for a product that I knew was probably crap convinced me otherwise. I would like this same idea but whith LED filament even more!

China is a very big country, and I think things are not as standardized there as in the rest of the world maybe. My understanding is mainland china is mostly 220V 50Hz, and I'm not sure but I think they use both American-style and Australian-style outlets, though the Chinese ones are slightly different than the actual US or AU ones. I think ungrounded outlets are US-style while grounded outlets are Australian-style. I also get the impression that it's not uncommon to find dodgy "universal" outlets in hotels or offices, and also maybe some places have 120V. But it gets more complicated if you start talking about the special areas like Hong Kong. Hong Kong is also 220V 50Hz I think, but they use type D and type G outlets as a former British colony. Taiwan also uses 110V, and I think US style plugs. (Yes Taiwan is not under PRC control, not trying to start that debate :P)

Add a fusible resistor and remove one current sensing resistor to reduce the current and it will last for years.

8:03 R U KIDDING ME GUYS?!?!

You are more funny than the package

This thing can be made decent just by adding a fuse and stuff like that, and redoing the soldering. But of course you need to be able to open it without destroying the package!

Now I want to go buy one

- This is not the right way, but we like it anyway... Now you sound like UK DJ Solarstone :D

I imagine that the redundancies are from automatic translating where 2 Chinese items are simplified to a single English word or object (i.e. two types of street lamps). However, automatic translating doesn't produce typos so the writing was translated and then transferred by hand into the print files. Bizarre.

Nice Video :). Would love to see the calculator in another video! I have one with those vfd tubes too (But it's a bit smaller).

Great channel.....many thanks!

"Vyrobeno w Cine" && "MADE IN EU", hmmm... even a stupid label contradicts itself. I'm not surprised that MCPCB is used, theoretically it should help with heat dissipation, but since the strip is enclosed in a plastic or glass helix, the hot air can only travel upwards into the sealed case where it can't really exchange heat with the environment. Nice circuit design, but the unsoldered cap leg was definitely a bad thing. Looks like it was soldered by hand, at least the THT part, and a mistake happened. Nice VFD calculator! Non-destructive teardown, please.

I had one of these since 2012 and it lasted until last year, it finally died because of corrosion, the glass tube is all crusty because it burns the dust and bugs that step on it

China is having a lot of power cuts lately in some cities, so the grid is more like 0v instead of 86v. :D

I would like to see a video of how you can make the schematics. Very good channel

I love your calculator!!

Just the engineering behind this and production cost they could've just made a simple but robust LED light

in most of that Chinese junk, the wires act like a fuse

What a genius way to stuff led strips into an CFL housing! If leds' temperature does not exceed specifications.

The fact that watts are unit for power its widely used for different types of applications that marketing will utilise confusing ambiguity to catch consumers attention but just remember an led light bulb W rating is its power consumption unlike a laser pointer that doesnt advertise consumption that is rating for output :)

Hahahaha, what a translation, incandescent "bulos" which in Spanish means hoax XDDD.

This buck regulator board is very common in India for replacement for original buck regulator in 9 to 12 LED bulbs for which It costed only ₹20 per piece few months back. Drawback is that output voltage is little higher than required.

At least it has holes in the housing for airflow over the driver, also the leds are seperated from the driver. if the components are of reasonable quality it should last a long time

The heat in that tube must be baking. Those strios look like the 40vdc in my shop that I had to repair - they melted the masking tape I was using to temporarily hold down an end.

Cute content of dodgy product 🤗🤗🤗🤗

I personally like the LED E14 lamps in the style of the first old Edison carbon ribbon lamps with a "designed" radiation temperature of 1800 K. The flexible substrate was really a technological challenge in the development of this light emitters. But I like them because of their candle like radiation temperature even if you sacrifice a good percentage of COP.

Those EXACT LED lamp, are available in my country for around 3 years now, available in store called 1$ store. So when you buy something from there, do not expect for the best technology quality available. I still got 2 plugged in the ceiling at my balcon. We do not turn it on for a long period, just when someone need something there during night, and so on, that is why , they are still alive. In salon or kitchen, same model lasted for 1 month or 2, then there build in LED started to burn 1 after another... very bad cooling...

The small circle is what is used as a period (full stop) when using a Chinese/Japanese character set. The reason being that the solid dot is used to indicate a short stop between syllables in Japanese, as for Chinese I don't know as I can't read it well.

Small circle is the Chinese dot。 China domestic power is 3Y220. Line to Line is 380V, Line to Neutral is 220V.

They probably had a warehouse full of unsold CFL bulbs.

Would definitely like to see inside the calculator!

I have the same, but with the standard CFL design. I've bought it for 3€ in Normandy, as the factories won't be able to sell it because of the design. So they sell it cheap! Maybe they thought people would enjoy this kind of light bulb, and still continue producing the CFL design at the same time? I dunno XD

I love your videos about crap devices 😉

Who is from Czech knows that the texts on the labels are interesting. :)

Thanks for this -= you have totally convinced me. I don't want any.

Já jsem pro nakouknutí dovniř té T801, klidně i překreslení schématu.

bloody helll. super dodgyyyyyy

There's a datasheet available for the CL1502 but it's only available in Chinese and the manufacturer only does commerce in Chinese...

It would have been nice to do measurements before soldering capacitor to see how it impact the output.

0:35 The small circle is common in many Asian languages, normally U+3002, &#12290 or&#x3002。

Looks like some basement diy.

China's power grid is somewhat unreliable so there is fluctuation of voltage and frequency but the nominal voltage is 220V 50Hz throughout the country. (Unlike Japan where the eastern half the country uses 50Hz and the western half uses 60Hz)

the bang will be the brightest moment i have a similar lamp, bought on purpose for 1€, it has the previous version of the CFL tube (the multiple U shaped one), still glass, never used it, i keep it as a collectible LOL i know it sucks big time, also the LEDs are eye piercing

Needs to recheck bulos after CAP resoldering and 230VAC mains. Funny bulos anywayos.

Very interesting 😂😂😂😂🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣

Yes you should open it :)

The closest Chinese bazaar to my house prints its own stickers with custom barcodes, a fake CE mark and "Made in China" so everything becomes instantly CE approved and Chinese, the funny thing is that a few categories of products are actually made in Spain or other EU countries and comply with all EU regulations, they do not import certain products from China simply because their customs tariffs/taxes or something similar are very high to avoid unfair competition with local companies.

"Made in Eeeyooooou?"

Top good!.

Whoa I just clicked on this video and there were 555 likes. Nice

The best part is reading Chinglish :D

Bro I think is great you to build EST Analog Meter & LCR Analog Meter with programing chip & sircuit design 👍🏻🙏🏻✨💖

I have one of those.

Its watt rating of 12 is input consumption not the lumens output....

12:02 why not using the square root button? 😁

Those weird typos must be OCR translation

1:54 Was that lamp made for export since its 240V rated instead of 230V?

I love your videos! Thanks for explaining and showing electronics also telling its safety it really helps! Also can I have a shoutout plz/please? I'm your 9th commenter!

Funny box

Shenzhen engineering at its finest

I sent to your email my version of 2 displays clock as i promised.

👍

I was surprised by the output capacitor. It's only 3.3uF and rated for 250v even though it only sees 35v. 15uF 50v would make more sense. They probably copied the value from high voltage LED string drivers.

Ordingaryly I don't leave a comment , but it is strange that in 2022 that somebody at the companies grandkids could not translate it properly for them 😁

Comical Chinglish! :D

The lamp is most efficient when you don't buy it.

that does not look too dodgy. unless the dodginess comes from the waveform kicked back into the electrical system. in theory if you have many of the bulbs connected the harmonic distortions could build up and burn your house due to electrical induction distortions and such.

Please make a video how do you make circuit diagram of any circuit boards

I've bought some extremely similar lamps at my local discount shop in the UK. The base is identical, with the same power supply, but the LEDs and glass envelope are different - instead of the helical design they have 4 U shaped tubes which each contain two straight strips with 9 LEDS (3s3p) The CRI and colour temperature are absolutely horrible so I just dismantled them for some nice aluminium LED strips to use in other things.

What is the conclusion🤣🤣

I’d buy one of those just so I can laugh at the false claims and see how bad it really is
