Found my invention made by someone else, lol.

Always knew a computer power supply & computer CPU heatsink would be used in a flashlight one day. Well here it is, not me but someone else.

That is a nice mod with the aspheric. I don’t know if it’s because it’s not properly focused or just the nature of such large LEDs, but the throw seems pretty weak based on the video.

I’ve actually seen someone use 12v batteries and a cpu heatsink on a 100w LED a few years ago.

A mains powered flashlight

Light goes out, oooops ran out of lead :bigsmile:

I think the ATX powersupply case was just a cast to hold the boost converter to run the LED module

Either way it’s a beast…Julian Ilett on youtube has done some interesting stuff with those LED modules

Plus I like his postbag stuff…he gets alot of those chinese modules to tinker with

Still 100 watts in a handheld unit…blasting the lumens! :smiley:

Thanks!

While it is the nature of huge, cheap COB emitters to have a very low surface brightness (which means they’ll have poor throw) I don’t think that this one is in focus. IIRC FL and diameter/thickness are correlated. As the lens gets ‘bigger’ it’s going to have a longer focal length. This lens is clearly positioned very close to the emitter.
