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 of the lens helps to reduce these reflections. It does this by changing the lens surface's refractive index. The XT11S uses multiple switches. The switches' placement and design determine this. They allow for one-handed operation.

The electronic switches may have a higher chance of standby drain. 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.
