Cree is widely regarded as a reputable LED manufacturer. Warm, white light is generally more comfortable. It's also less harsh on the eyes than cool, white light. If you need long-range light, get a flashlight with a smooth reflector. It will have more throw distance. The AR coating on the lens maximizes light transmission. This makes the flashlight more effective in darker environments. The electronic switches may have a higher chance of standby drain.
