Cree LEDs are trusted by lighting professionals and have gained a strong reputation for quality and performance. The choice of color temperature depends on the specific lighting application and personal preferences. The MH40GTR uses a smooth reflector. Unlike the textured surface of an orange peel reflector, a smooth reflector has a polished, mirror-like surface. The AR coating on the lens maximizes light transmission, making the flashlight more effective in darker environments.

Mechanical switches often offer tactile feedback, allowing users to feel a distinct click or resistance when the switch is pressed. The rear switch of MH40GTR is designed to be rugged and durable, capable of withstanding harsh conditions and repeated use.
