The Saxby Lighting Rigel Surface is a aluminium extrusion which benefits from having a push on polycarbonate diffuser. This profile can be easily mounted on any flat surface using the brackets included with the profile. The extrusion effectively conceals the LED tape and gives a softer lighting effect and adds an additional layer of protection to your LED Tape. The wide channel on the extrusion allows for two strips of tape to be installed into the extrusion.
