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:

I have a big cuestión, can I use a 10k resistance electric instead of a 11k ? 'Cause I don't know if it works equal.

You did not source the female round connector for the power supply. If I get a 7.4mm (OD)/5mm (IN) round connector for a Dell AC adapter will it show positive and negative on the connector for proper connection?

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.

Considering making one of these but maybe not quite 100w, maybe somewhere between 10w and 50w. If I did this would the circuit be the same. And how long did that 8000mAh battery last in this video?a

You should use insulating film between the heatsink and power transistors. It costs almost nothing.

That HP sause

Author Tom Brown ( ago)
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.

Just to repeat my question, do I need to solder on the two 11k resistors to the
dimming mechanism if my boost buck converter can also limit the current
at a specific level (i.e. has two dials one for V and the other for I)?

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?

That is pretty awesome. I'd be tempted to find a fried Ryobi tool, take the socket for that, and use the Ryobi 18v batteries. I can then use the charger and swap batteries quick and easy and charge them using the normal charger.

Hi Matt,
First of all i would like to say that i am fan of your DIYs and the quality you achieve.
Thanks for your videos.
After watching your video of " Make a 1000w equiv. LED flashlight - aka DIY
Sun-Blaster! ", i tried a similar one and was successful. i have
installed it on my motorcycle for long highway night drives.
Though the light output is extremely bright, however, i am able to use it only
as flood beam. as the Glass lens has a beam angle of 60-80 degrees. (physically appears to be covering greater angle)
My intention was to use it as an focused spot beam light. Is there a possibility to work around to get a narrow spot beam angle say
30 degrees? Or is there any narrow beam lens available online?

Author Jezro Shevy ( ago)
@DIY Perks I am a bit confused about the resistor you used at 4:10, can it be any 11k ohm resistor because there are a few different types of 11k resistors on ebay ranging from "11k ohms 1/4 Watt" to "11k ohms 1 Watt." Your response would be greatly appreciated :)

I swear, I just saw my very first UFO right there!
