Utilihab T-slot Sconces are surface-mount light kits which feature a lamp enclosure designed to attach to profile slots in Primary or Secondary framing with wiring concealed in the profile slot channel. They are usually designed as up-lighting, down-lighting, both up and down lighting, or diffuse side lighting. Many variations are possible but the typical forms are tubes, half-tubes, and boxes made of aluminum, wood, or translucent materials designed with back or base plates that compliment the standard framing profile dimensions. Exterior styles are weatherized and usually designed for mounting on exposed Primary posts with slot cover plates to protect wiring. Interior forms are usually designed for use in combination with the flush mount panel system and mount over or in-line with wood finishing strips. They will usually employ conventional lamp sockets or, for low-profile forms, bayonet style sockets.
