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 H40 XPL has an orange peel (OP) textured reflector. Orange peel reflectors have smoother beams. The coating is thin and applied to the lens surface. It cuts reflections and boosts light transmission. Some flashlights with electronic switches have programmable features. They allow users to customize the behavior of the flashlight.
