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 designers of the SP33 v3 incorporated an orange peel reflector to enhance the beam. The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. Some flashlights with electronic switches have programmable features.
