Lighting professionals trust Cree LEDs. Cree LEDs have gained a strong reputation for quality and performance. The color temperature choice depends on the light's use and personal taste. The DV55 uses a smooth reflector. A smooth reflector is different from an orange peel reflector. It has a polished, mirror-like surface. The AR coating on the lens maximizes light transmission. This makes the flashlight more effective in darker environments. Mechanical switches often offer tactile feedback. Users can feel a distinct click or resistance when they press the switch.
