Hi electrodj, nice idea !

And btw: :welcome:

Could you post a picture of the "cpu heat e[x]change" ? I'm curious how you are going to move the heat away from the LED. I suspect, either the LED will overheat or the lamp-body will melt - or both.
:candle:

Re: eveready ONE mod 3watts and 5watts led



after a while turns hot +-40ºC not enough to melt the lamp body .The regulator keep the current constant

BTW this led is a real 4 led on one, 2 on serie and 2 on parallel this means v drops of 7,4V and 750mAh for 5watt

I think that was a "cool" idea to use the
cpu heatsink in a flashlight. Nice work!
