The LED is being run at its peak, but the higher the temperature it is at the lower the output.
Usually I try to use larger CPU heatsinks, at least ones with heatpipes to move the heat away from the MCPCB faster.
In this build I had to use a low profile server heatsink and low profile fan to keep it compact.
It’s still better than just a passively cooled flashlight body, but not as good as the BXTS13A I used in my previous builds, and far from as good as something like a NH D15 which would be the best possible scenario.
Maybe I’m still too newbie to understand or I just prefer flooders, but…
what is the point of making such flashlights?
Except for fun.
Too large for short distances. And too focused light.
For a long distance illuminates a small point and you need to use a binoculars to see anything.
There are actually a small minority of BLF’ers that can use a good thrower like this. For the rest, it’s just a toy. I don’t have any use for a thrower, but I’m definitely impressed by the reach of these things. I’m not a flooder either, though. I prefer a medium size hot spot and a decent amount of corona, with very little spill. Some of my favorite lights are TIR.
Yeah mostly for fun, it’s like a fat laser with a very visible beam that isn’t dangerous to the eye and can’t cause fires.
At 1 or 2km the spot is large enough to light up a house, so even though you can’t see very many details from that far away you can still clearly tell that there is a house, without using binoculars.
Your vision is better than you think, look outside, you can still see stuff at 5, 10, 15km away.
Yeah I haven’t had time to machine the piece of metal I need to hold and cool the crystal and laser.
Hopefully once school starts in september and i have access to the machine shop again
