A:Answer It depends on the color of the translucent cover and how much light it blocks. If you use matte or milk-white Plexiglas for the cover, the loss is minimal and the color shift negligible. Most of the time, my Hue lights are not at full power so if there was light loss, it could be compensated by setting the brightness a bit higher. Be sure to provide sufficient ventilation in the enclosure. While LED lights run a lot cooler that incandescent lights, the electronics still emit a certain amount of heat. Overvoltage and heat are the biggest factors in shortening the life of modern LED lights like the Philips Hue.
