Cree is widely regarded as a reputable LED manufacturer. Warm, white light is generally more comfortable. If you need long-range light, get a flashlight with a smooth reflector. The AR coating on the lens maximizes light transmission. The TH20 Guardian uses multiple switches. They allow for one-handed operation. The electronic switches may have a higher chance of standby drain. Mechanical switches offer tactile feedback. Users can feel a distinct click or resistance when they press the switch. A simple press or click of the rear switch turns the flashlight on or off.
