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. The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. Mechanical switches are usually robust. The rear switch of the I331 is usually operated with the thumb or finger.
