Luminus has established a positive reputation as a reliable 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 of the lens helps to reduce these reflections. It does this by changing the lens surface's refractive index. The electronic switches may have a higher chance of standby drain.
