How To Make High Power Led Light At Home 40 Watt 

No Calculations, no resistors, but it got a million views and 312K subscribers thus far ? Must be the quality workmanship I'm guessing.

Good vedio forget about rude comments. Ur vedio is perfect for those who want cheap aquarium led lights . All they need is use one red and blue led and two white led . This combination will make it a grow light. For aquarium we need to work them for minimum 7 hours continually . So fan is a must . Thanks for Ur vedio . Great

Craftmanship in perfection. I would try to get heatsink paste and hotglue in buckets, so you just could throw the parts in, to make sure it is really everywhere

Direct to 12v battery. Bravo. U will earn so much from this scientific revolution.

very messy when you apply the heat sink compound

Kya is ke sath koi driver add nahi kiya ja sakta tha? Ta ki bijli me bhi chalata .

Cool idea and not bad for the first time you're working with COB's but... Electronics need work before you blow up those COB's, soldering job is barely adequate, mount screws go through the holes in the not in the corners and please work cleaner.

please suggest me a bright led light strip (approx 25-30 watt max) for mirror, this LED strip i want to put/place surrounding on a shaving mirror

Terrorific terrorific proceso de fabricación

Tidak pakai resistor?

You will get a Nobel prize definitely or an Oscar at least. Guess that you should have a bharat bhushan with your name !!!

I like your project. I have led chips on the way and i need to know how to mount/cool them before they get here. Thank you for the video.

wow,, amazing. i remember to my playing in Basic School

What paste did u use to fix the led?

video achih hai lekin ap ne yeh nahi bataya k in pr kiya lotion lagaya hai?paste ka nam kiya hai?

Nice to see I arnt the only one who has great trouble soldering....

IS THE CONNECTION DIRECTLY ON THE BATTERY NOT GOING TO DRAIN THE BATTERY QUICKLY?

Havent you heard "resistor" buddy?

What if I want to connect 6 pieces in parallel to 12v. (12V to 14.5V in boat).? Which driver then use?

Bro use 240v, 135J capacitor and make a bridge rectifier using 4007 diods and connect one 50 v 47 uf capacitor and at the positive end of rectifier use 40 ohm 1 watt resistor...the led will work directly in 240 v.

How hot does heat sink get after extended use, say 30 minutes?

Love your videos but I was just wondering where can I get some of these led lights from

Very good

12v 1m adapter can support one led chip ?

No current limiter??

friend. Do not you use drivers? Then how can turn 40w light without driver

You need todo work more carefully And less mess! This is terrible work and poor soldering. Always tin with solder before you connect wires to contacts. Screws too big, wires too close to heatsink can cause short, before applyìng paste be more careful & professional not to make such a simple mess (your making a video for others to see). No need for fan with that huge heatsink and 40watts only makes about 98 degrees Fahrenheit. Practice first so you show a more prof job on video cause this is very poor workmanship. THE IDEA IS NICE ..PRACTICE I MUST SAY!

Please tell value of power supply and calculation of total load with fan counted. Good vedio.

Very nice

donde agarras Las LED lights , para hacer uno como el tuyo

Hello Sir main solar panel ke sath chalne wali streetlight banana chahta hun please help me

hi man , it's ok , do this circuit need a resistors ? or it is conectid to cd suply?

Whst is use of fan ?

shabby workmanship

I have followed the neceassry instruction except that i am using a multiple ac/dc power source. Why is it that when i switch on the light, the fan stops and when i switch off the light. The fan runs. A little help may do. I have little knowledge of electronics but i know most its parts needed. Thanks!

I have red, green and blue one like this and I am scared to connect directly without resistance 1 or 5 ohm 10W. what can you say about it.?

You first need to learn how to propper solder a wire! You heat that wire to much on a plastic switch witch can be damaged. Add tin before solder two wires. All wires must have tin on it and than you just need to touch them with soldering iron.

Olá vc saberia me dizer quantos leds desse posso ligar em uma fonte 12v de PC ?

Bhai wo bada wala LED kahan Milta Hai........

background music Ke Badle explain Karte to better Hota

without a current regulator The LEDs will be damaged in a matter of hours. Very poor soldering. using the soldering iron to shrink the rubber tubing is a very bad idea. First you learn how to solder.

Keya bike ke liye led light bulb banaskte he

Sir, thoda detail mein samjhate to achha hota. Led white ya led warm ? Sahi quality led kese choose karein ? Led price ? Kahaan milega sahi price par ? Led ka lumen ? Ye Jo unit aapne banaya he ye kitne lumen ka bangaya assemble hone ke Baad ?

Where is the LED driver? So I do not think that lasts long those LEDs

Can we use this on 12 v choke

Konsa wire kaha Joda jata h koi batayega

Bang saya mao pesen bikin rangkaian lampu kaya di video bisa gak ?

What's the ampere limit it can resist ?

What the hell is it ? Where is driver for led? Can't connect directly power to the led like that , don't do it wrong way to build led..

what?! what is this?! 4x10W = 40W math. 100x10W = 1000W If I find a driver with the right current, it's no big deal. It only costs more than buying a complete one. not to mention its casing is ready to buy, it's aesthetically pleasing, I don't even remember. Existing stuff is not difficult to make, starry sky is the limit. Need to build a led driver! Make an LED, not a 10W-20W battery, if it succeeds, show it. There is nothing in it. Basic electrical knowledge is already possible. And the net is full of such self-proclaimed geniuses. Those who play it reach into the drawer, take out a handful of led batteries, power supply, and unexpectedly put together a series of 10W led panels. From the stuff you buy, it's not a stunt. For example, if you make a space cabin out of a refrigerator, which is pressure-resistant .... well, or you make it from waste, it's not an artwork, it's a really useful, usable thing .. yes, that's something. This has already been done on another channel. Even bigger. You must have seen it, too. What would you like to show? How can you make it? They succeeded. Congratulations, Ellemben didn't make much sense. At least make something that is not yet in the fray. No copying, little bit of variation, plagiarism.

Nice what neme for whit colur paint

Alguno que me diga que eso es pasta termica y no es plasticola por favor (Someone plz, tell me that is thermic paste and not school vinyl glue)

Aap ko nhi lagta Hole kam kiye h abhi jgah or h

Sardar charging light 3.7 volt cut cut banana hai to Kaise Banayenge

what is it name leds below gray thing?

use it from dusk till dawn and it will not last long. current limiting resistor is needed. i've done this.

Noch ein lieter wärmeleitpaste😜

What about the working time in that battery

Bagus.. Tapi banyak minusnya.. Kurang rapih Kurang aman Kurang perhitungan Tanpa LED DRIVER??😫😫😫 dan sayang dana yang di keluarkan.. Selebihnya 👍👍👍

А где защита светодиодов от перегрева если вентилятор сломаеться?

nice.. ican used 12volt adapter on input volt.

is thre is need of fan for cooling.....

Y light kuch time bad dim Kyo ho jati h (5mint)

Led price plz

Sir heat sink kaha milega Or price kya hai

Green led milegi

It’s not that impressive at all. Can do that with a blind fold.

*How NOT to power a led light!!!!!!!!!!!!!!* Where's the current limiter resistor????????

10w led price

Perfecto

Great

pori video ma naya kia tha ???

You Suppose to be engneer maga, even for 12v supply u used wires like this, what about 11kv supply ...........

bro have a question how many price of battry ...

Looks pretty good until he whipped out the screws and then the glue gun lol.

Plz apni Awaz k Sath video banaya kro .. Aisay theek samajh nai aati...

great

Looks like video is from India, they never clean their irons.

Sir e pipe Ka name keya hain

nice bro.....

READ *******as long as the fan blow toward fins not away its inefficient to suck air past fins its common sense THIS LOOKS LIKE HE HAS IT WRONG

Sooo Good Sir

Craftsmanship and quality are a thing, Just not your thing clearly.

make a led chaser ic number 12f629 please make bro

Nice

Nice work 😃🤔🤔😱

How much hours can it work for continuously?

Needs driver dude .

LED light in the 40 watt range.

I hope know one lets you near anything with more than 12 volts.

Good job but messy good luck

Power

Poo waooo

OH GOD, my eyes. WHY. please watch how to solder and then post videos. OH GOD.

controlla assorbimento vedrai che corrente alta.

Kaam Ko Finishing K Sath Kia Karo Khachada Lag Rahi He Light.

That hot glue 😢😢😢

awesome custom,,,,i sub u
