INSTALLATION

The P-45 Series fixture may be installed as a wall mounted unit with standard Baked White Enamel finish or optional colored paint finishes. The fixtures may also be placed into a cove provided by others. Minimum cove interior dimensions are 8-1/4" wide by 5-1/4" high. For maximum efficiency, the wall and ceiling above the cove should have high reflectance matte surfaces. The fixture should be tight against the wall to obtain uniform luminance.

  1. Socket shadow deflector
  2. Semi specular reflector (Aluminum)
  3. High reflectance white reflector (Steel)

We reserve the right to change details of design, materials or finish in any way that will not alter appearance, reduce function or performance.
