This is a VERY bright compact 100 Watt LED flashlight. It is powered by a 3s lipo battery and a led boost converter/controller. I have build many powerful flashlights before, but this is my favorite.

Parts:

The part list for this build is fairly short:

  • 36V DC-DC boost converter (the white ones with aluminum pcb)
  • 3s battery indicator
  • 40mm*2 black heatsinks
  • 3s lipo battery (I used 2200 mAh)
  • 100w led chip 

Additionally you will need:

  • XT60 connectors (for connecting the lipo battery)
  • an old cpu cooler (the older intel stock coolers always work great for this)
  • a switch
  • a lot of M3 screws
