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.

Mechanical switches often offer tactile feedback. Users can feel a distinct click or resistance when they press the switch. The rear switch allows for quick and easy momentary or constant-on activation. It enables rapid response and tactical moves.
