Brilliant DIY Project. By the way, aluminum cpu heat sink alloy is very strong. Everyone assumes it’s soft and ends up shearing off screws in it. Aluminum CPU heat sinks should be drilled and tapped. Also, they now make LED drivers little step up from 12 V to about 40 V. That will allow you to use a 12 V rail and not have to use a boost circuit. Then again, using a boost circuit as a driver gives you flexibility as far as dimming control. You could also buy LED drivers that have integrated dimming control. Anyway, Lots of ways to do this project. I really enjoyed your approach because you use just about every single DIY circuitboard you could possibly buy.
Very cool project. I did very similar lights using old studio photography flashlights with bowens mount. I removed bulbs and electronics and retrofitted COB LED. I like how they look and they have great ergonomics. The only drawback is that they are very bulky since back in a day studio lights were much bigger than LED lights nowadays. I figured out how to you can control the brightness using a microcontroller and was thinking of making them controllable via BT or WiFi using ESP32 module.
Thanks! That was actually my idea as well at first, to re-use an old studio light to have the COB LED fitted inside, but it was quite difficult to source any. And as you said, they are quite bulky. Sounds awesome to have the brightness adjusted using a microcontroller.
I just wanted to drop a comment that opening any power supply is incredibly dangerous. The large can looking things soldered to the PCB are super capacitors, and people have literally died doing this. Those caps can hold their charge for a LONG time, so even if it's been powered off for a while you can still get a fatal zap. Most modern PSU's have protections built in, like drain resistors, but this is something that absolutely should have been mentioned in the video. Somebody, or the family of somebody, who is following your instructions who is hurt or killed would have a pretty solid case to find you at fault because you didn't warn of the danger.
Found the NPC. Just cannot help but fall to the compulsion to outburst electrical danger at the merest whiff of electricity... Not helping like you think you are... how do you think the device this is viewed on, is powered? You've already missed "firstsies" on the viewer by several years involving hundreds of dangerous situations by the time they can find the video and have the patience to read and understand what you wrote. Loser.
Also discharging them improperly can be dangerous, I’ve accidentally welded capacitors into a short trying to make them safe to handle. Some capacitors have enough juice that connecting the terminals with something conductive (like your body) is enough to melt metals and the physical size of the capacitor is not always an indicator of how much energy it can have.
How do you know wich resistors you need ? The 103 should be a 10k but you used 6k combined. And if i have a 104/100kohm resistor would i need to use 3x 20kohm ?
Much appreciated, thank you. Since I had some of the parts laying around, the main cost is the LED chip, of course. I would say around 80-100$ for each light.
Since I don't feel the need for a strobe LED, I won't be making one but it shouldn't be difficult to integrate a strobe controller or high frequency switch to the light.
@@westleyleonstudios I can only think of the possibility of it being doable but I wouldn't put my hands on a project like that since I don't have use for it.
Since the LED operates from around 34-37 Volts, it is easier to use the boost converter to increase the voltage of the 24V power supply to have the full range of the LED rather than a 36V supply that you can't regulate below 36V.
Well this is honestly cool and all, but with the amount of money you put into it you could of just bought one and saved yourself the time and hassle of building it and waiting for all the parts to come in the mail.
CRI is not a good unit of measurement for color rendition. TM30 is better, which is what high end brands measure. CRI may be 97, but TM30 doesn't touch 90. These AliExpress "grow lights" are resells of leds that didn't meet bin requirements

Amazingly good work... Only one concerned it's the flicker for video!!!
I'm proud of your precious work!!!
Marvellous work, very clean DIY. Congrats.
Thank you so much!
Useful video that can be applied to different type of lights, such as stage lights in my case.
Amazingly good work... Only one concerned it's the flicker for video!!!
I'm proud of your precious work!!!
You haven't listened until the end 17:20
🤩❤️ Awesome, Nice can adjusting brightness, Thanks for showing each steps … Great build !
the best dIY i saw so far about Pro light low budget ! well done for it

what a genius! keep it up good sir
awesome... your idea very good... succes my friend
literally...amazing 🌻🤍
Thank you
You didn't show how you set the voltage on the boost module. How do I do that before connecting it to the LED?
Very very well done sir. So excellent
How do you know wich resistors you need ? The 103 should be a 10k but you used 6k combined.
And if i have a 104/100kohm resistor would i need to use 3x 20kohm ?
what would be the overal changes of resistor and power supply to adapt the exact same build with 200W or 300W LED ?
Yeah, that is really cool!
how much did this cost to make??
Amazingly good video. Very clear and good descriptions. Now if only I could be bothered to make one. How much did it all cost?
Much appreciated, thank you. Since I had some of the parts laying around, the main cost is the LED chip, of course. I would say around 80-100$ for each light.
You just raw dog that power supply, damn
I was wondering why you used 2.5kOhm when the component you normally remove is 10kOhm?
Thank you for your video. Can you explain why you chose 10k variable resistor with 2k?
Can you do a similar strobe LED light?
Since I don't feel the need for a strobe LED, I won't be making one but it shouldn't be difficult to integrate a strobe controller or high frequency switch to the light.
This guy is definitely from other planet
Super! Thank you very much!
Good one. Thank you! Can you provide how much you spent on this build?
Thanks! It cost me around $80 per light.
Nice job
Thermal senstitve fan with the controller is good.
Caution: follow this video if you want similar nicks in your hands :(
Wonderful DIY project LED. Would you sell?
Very nice video.
I can't access the link you provided. Can you give me the product or proper link to purchase it? I will be grateful to you
Hi, I will try adding amazon links if that helps.
Hey! Can you do this with BOTH an LED light AND a Flash tube for flash photography!?!?
Hey! I'm sure that would be doable.
@@DonnyTerek I’d love to chat about if that is possible!
@@westleyleonstudios I can only think of the possibility of it being doable but I wouldn't put my hands on a project like that since I don't have use for it.
@@DonnyTerek If I invested in the items for you to make it so you can make the video for content - how much would that be?
@@westleyleonstudios I'm sorry to say but I wouldn't tackle a project like this due to many other in queue.
You cane make conical snoot simple mr plis
Bro one question how did you set the voltage of boost converter?
Hi, the voltage is set by adjusting the potentiometers as shown in the diagram of the video.
super cool vid
Thanks! Much appreciated.
Very simple, I'm gonna build 3 or 4 in the next ..... 3 or 4 years 😂😂😂😂
Very Nice !!
Thanks!
why u dont buy powersupply 36v and dimmer . 24=>36v=>12v??
Since the LED operates from around 34-37 Volts, it is easier to use the boost converter to increase the voltage of the 24V power supply to have the full range of the LED rather than a 36V supply that you can't regulate below 36V.
@@DonnyTerek If using a 36v power supply and a convert 12v low voltage circuit for the fan, is the cost cheaper
@@benhviencapcuu3960 yes but you don't have the option to dim the LED.
this heatsink looks smaller than i expected for a 100 watt led, are your lights still working ok, do they run at a reasonable temperature?
Probably not.
Brilliant job❤️❤️❤️
Thank you.
can u make them and sell?
Hi! I am planning to keep these for myself for studio lighting.
Well this is honestly cool and all, but with the amount of money you put into it you could of just bought one and saved yourself the time and hassle of building it and waiting for all the parts to come in the mail.
Yes true if you build such a small one
Yes, I definitely agree. But I wanted to have a compact unit with the integrated power supply, that's why I decided to make my own.
Perfect

Why don't you use that actuall computer power supply, it give you better output power delivery
Because it's only 12V, and takes up a lot of space
😍😍😍😍😍

Hi.
just a heads up. there is an imposter of you that is a scammer. Check out my comment on the custom boombox video, the one with a subwoofer.
This DIY is not for me, a beginner.
Guys please be careful psus are dangerous so please at least watch a tutorial on what not to do before opening it.
fucking awesome work man!!!
