How to build Cree XHP70 flashlight Disclaimer - These are Amazon and eBay affiliate links. I am currently in the research and development phase of building my own quad Cree XHP70.2 (6V) flashlight. I will be running it of 2S 18650 but would like it to be 3S or 12V capable. I plan to build an I2C controllable LED driver so I can reuse the driver in a single LED flashlight in the future. The XHP70.2 performs much better than all other tested LEDs here. The overcurrent capabilities are better and the light flux maximum is at over 20 amps – the maximum range of my power supply. Moreover, the Vf is a lot lower than that of the other emitters, which improves the efficiency (lm/W) a lot.

I purchased a pair of Cree 12v XHP70.2 LED's, modified the heatsink to mount them in behind the lenses, and wired them (in series) to the driver. However when powered up, the system does not illuminate the LED's. They very dimly flicker at about 20-30hz. Automotive voltage drivers are severely lacking out there, but depending on which die (forward voltage) arrangment xhp70 you go with, you may get away with an offering from taskLED. http://taskled.com/compare.shtml My first torch build using: 7x cree XHP 70 leds 7x random ebay reflectors 7x random ebay voltage/current adjustable drivers ebay heatsink 80 mm computer fan Running off a 4s Lipo.
