The plane marker is an LED-based luminaire that casts light from the edge of the housing, creating the illusion of a "floating plane." Outdoor applications include building and bridge demarcation. Excellent for 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 and environmentally sealed, enclosed and gasketed 5.9" sq. corrosion resistant metal casting (stainless steel optional) which mounts directly to a UV stable, optically clear, high strength polycarbonate housing. The LED luminaire module contained within the housing is replaceable. The plane mounts directly to a junction box while the driver resides within the junction box. Projected average rated life is 50,000 hours at 70% of lamp lumen output.
