Make a 1000w equiv. LED flashlight - aka DIY Sun-Blaster!

Here's how to make a phenomenally bright 1000w eqiv. LED flashlight!
Here's the LED we'll be using:
It's designed to be operated with just one hand, with easy control of brightness, and can be powered by either batteries or an AC adapter.

Can be built for around £25 if you get the CPU cooler for cheap.

Major parts list (worldwide shipping):

Heatsink, fan, lens, and mount:

100w LED for UK/EU buyers (includes lens and reflector):

Other parts:

Lens and Reflector:

Voltage Booster (there are two layout varieties floating around. If yours has a different layout than the one I used in the video, then use your own judgement when it comes to wiring up the input/output wires, which should be clearly marked on whichever layout you receive.):


High-Capacity Battery (lasts for AGES):

CPU Cooler (Titan Fenrir in my case, but you can use any tower style cooler you like. Used ones can be found for around $20):


10k Potentiometer:

Heatsink Plaster:


Mini Step Down Regulator (for the fan):


60cm Aluminium Bars (UK only):

XT60 Connectors:

Full parts list, with remaining components:

If you attempt this project you do so at your own risk. I assume no responsibility for any injuries or damages caused to people or property during its construction or use.

I have taken care in making sure the information in this video is accurate. However,I am unable to provide any warranty concerning the accuracy or completeness of any information contained in the video.

I want 6 of something like this...I'm in the process of tinkering now...2 each for the front/back of the house and one for each side all wirelessly controlled by one central unit (rf and/or Bluetooth) to be constant on, synchronized strobe, and individual on/off/effect control of each unit separately so I can light up the yard at 2am like it's 12noon on demand! ...I'd also like a fairly fast chasing effect SO I can make the house look like a UFO about to take off, just for fun and possibly an additional option for PIR triggered security (add on switches) so depending on the effect being lit I can know immediately where the motion was sensed/triggered ....fairly big, long term and hair tearing project so far....can't wait for all my testing to be done SO I can build the final ones to mount on the roof!'s one of those projects that you want really REALLY bad...but you have to walk away from quite frequently in order to not take a sledgehammer to what you're working on haha

Joachim BichlmaierJoachim Bichlmaier (2 months ago)
How can you use a Laptop adapter that puts out 8 Ampere, if the step down regulator can only deal with 3 Ampere? You connected the step down regulator directly to the input of the voltage regulator, so the 8 Ampere go directly to the step down regulator for the fan, or am I wrong?
I am building this thing at the moment and my step down regulator's LED is blinking and it doesn't work. Could that be because of the too high current? And how did you solve this?

you really want to sell this as a 1000 W equivalent torch?
You know that a normal halogen torch with 1000 W would have about 27000 Lumes. Your chip is rated as 1100 Lumens @100 Watts. But having the least knowledge of LED'S you would know that that that is fake value. Else it would have a value higher then then the best led's on the market at this power and just cost 20% of them.
These kind of chips, normally measure @80 Lumens/Watt at about 25% current. At full current way less.
Also by running an LED on full current you show that you have no idea of high power led's. Didn't you wonder that no real datasheet was available.
Also learn how to add the heat conduction paste propper, your way you are just creating a bad connection where the paste actually acts to much like a retardent.

Would be perfect for camping and road trips but what about the rain? Won't the power supply and components get damaged from getting wet? Wouldn't it be safer to have an enclosure around it somehow? Really cool project though and I love the aesthetics of the heatsink. I thought it was the Cooler Master 212 Hyper EVO at first.

how much heat does this output? Could you get by with a cheaper (or spare) CPU cooler like an Intel LGA1155 stock cooler?

LolwutfordawinLolwutfordawin (4 months ago)
The intel stock cooler will struggle to keep it cool without having the fan running at maximum (very loud). It's designed for 50-70w CPUs, this outputs closer to 100w of heat.

1000W?!?! i thougth it was a 100w led. or you mean 1000wh akku

Kai StümerqKai Stümerq (3 months ago)
even if the rating of the led would be true, it has only had only 30% of the lumens of a 1000W halogen light, but the least knowledge about high power led's would tell you, that the the rating on ebay is fake. It's to bad, but the data written down there are better then the best actual led's which will never happen an led only costing 20% and repeated getting tested as just being as efficient as a good halogen light.

Okay so I have my resistors hooked up just like he does in this video I couldn't find 11k ohm resistors I used 10k at first and then added and tried both in series and parallel an 1k still coming out lower voltage output. I have the blue potentiometer turned all the way right for max output and my 10k big pot turned all the way right I'm outputting 19.6v I thought I was doing something wrong so I hooked the little blue pot back up way it was made and the voltage booster outputs 42.6v. Is there something I'm doing wrong do I need these resistors in there like that?
