MOONRING ARCS are individually formed quarters of our popular MOONRING luminaires. They’re available in several sizes with either 1.5″ or 3″ apertures. For MR1.5 ARCs, specify sidewall combinations and optional two-two finishes. For all ARCs, specify light output, LED color temperature and rendering index, dimming, emergency and sensor options. All MOONRINGS now feature TUNEABLE white and RGBW lamping options.
