<p>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.</p><h3>Parts:</h3><p>The part list for this build is fairly short:</p><ul><li>36V DC-DC boost converter (the white ones with aluminum pcb)</li><li>3s battery indicator</li><li>40mm*2 black heatsinks</li><li>3s lipo battery (I used 2200 mAh)</li><li>100w led chip </li></ul><p>Additionally you will need:</p><ul><li>XT60 connectors (for connecting the lipo battery)</li><li>an old cpu cooler (the older intel stock coolers always work great for this)</li><li>a switch</li><li>a lot of M3 screws</li></ul>
