The shallow profile of SP makes it the perfect perimeter selection where minimal ceiling penetration is desired. It is available in semi recessed or fully recessed versions with fluorescent or LED light sources. Housing and vertical fascias are extruded aluminum, and the extruded matte white acrylic lens snaps into the housing. SP is available in 8, 6, 4, 3 and 2 foot sections. A 6 inch staggering of T5, T5HO or T8 lamps is standard.
