I now buy UltraFire C8 shell relatively large, open for a long time no temperature. Also, it says 8 hours of continuous light. I think it's almost impossible. The 1700 MAH rechargeable battery can be pretty bright for 1 hours
Never mind the heat, because your flashlight shell is too small. The heat is not good is normal, my UltraFire C3 longer than you, the heat is not good, open 5 minutes light is very hot, I drove for nothing more than 1 hours.
