Whitestar Series Technology
The Whitestar high color temperature series was designed to provide a balanced full spectrum MR16 for display and task lighting. These high color temperature lamps project high luminous intensity with low ultraviolet and infrared emissions to protect artwork and valuable merchandise.
Whitestar lamps utilize titanium oxide hard coatings on the reflector to maintain consistent color from lamp to lamp and throughout the life of the lamp. A proprietary dichroic coating on the front glass reduces yellow light while enhancing the blue and white light spectrum in 4200K, 4700K, 5300K, and 6500K lamps.
