Whilst adhering to strict energy saving criteria, Rays also pursues optimum performance and mechanical quality of the lightbox. As the Xxy value reaches 0.323/0.333, a system can be said to deliver an effect of 100% true white light, which guarantees faithful color rendering. Meanwhile, Rays’ “ultra-even light” reflective system can help achieve 90% evenness of surface brightness, eliminating unwanted “rib effects” and projecting a pleasant light with perfect image projection into its surroundings.
