LEP light sources can make a strong beam of light. They are good for applications that need long-range or focused lighting. Warm, white light is generally more comfortable. It's also less harsh on the eyes than cool, white light. 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 of the W3Pro Featherless Arrow is rugged and durable. It can withstand harsh conditions and repeated use.

These flashlights have very high intensity. They need lots of power and make a lot of heat, this is because they have high energy output. The throw distance is the farthest distance the flashlight can light an object. Candela per lumen (cd/lm) measures a flashlight's beam intensity. It compares this to its total luminous flux or output.
