For SureFire and other brands of incandescent(halogen, kyrpton, zenon, etc) flashlights under 7.2V we do not recommend this setup. We typically do NOT recommend these for any bulb flashlights - you use them at your own risk in these types of devices despite the voltage regulation at it takes the voltage regulation ~12 milliseconds to activate. They work GREAT for LED flashlights!
