The plane with luminous cube insert is an LED-based luminaire that offers a variety of different color combinations for edge glow and luminous cube center insert options. Excellent for exterior building and bridge demarcation as well as interior applications where ambient illumination levels typically do not compete (e.g., restaurants, clubs and some retail). Plane mounts directly to a junction box for wall mount applications. It is UL listed for wet or damp locations. The gem-like cube insert has been precisely molded using 1/4" wall thicknesses and the highest quality borosilicate glass. Diffusion properties are designed into the mold to diminish LED lamp image, offering a soft center glow, revealing the architecture of the cube. Projected average rated life is 50,000 hours at 70% of lamp lumen output.
