100W Ultra Compact Portable LED Flashlight (ultra bright)

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
