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 smooth reflector creates a well-defined hotspot at the center. This hotspot provides a concentrated beam for long-range use. 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.
