Cree is a US-based LED manufacturer. It is well-regarded for its high-quality products and innovation in lighting. Color temperature is a characteristic of light. It is used to quantify the color appearance of light sources. The designers of the G15 incorporated an orange peel reflector to enhance the beam. It does this by diffusing the light from the light source. The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. The flashlight has electronic switches. They have many benefits and extra features compared to mechanical switches.
