For a bolder, brighter blue or a more elegant, deeper green, Zeledyne Versalux® 2000T provides distinctive shades of difference. A titanium-based pyrolytic coating is applied to the Versalux Blue 2000 and Green 2000 for a brilliant appearance. Both offer excellent protection from the sun's damaging ultraviolet rays (300 - 380 nanometers). Higher light transmission results in a "brighter" interior environment.
