CONSTRUCTION
Luminaire housing and end caps are die formed
code gauge cold rolled steel. The aluminum
reector is proled to a precision curve and nished
with matte white paint for soft, uniform indirect
illumination. Matte white perforated light basket
backed by opal acrylic overlay snaps securely
into place and hinges down for ease of lamp
replacement. Thermoplastic light traps snap into
the housing at both ends of the basket to prevent
light leaks.
INSTALLATION
An access plate is furnished with each luminaire
for fast wiring access from the plenum. No need to
open xture.
ELECTRICAL
Standard class “P”, thermally protected, auto-
resetting HPF ballast, sound rated A. All ballast
leads extend a minimum of 6" through access
location. NEC/CEC-compliant ballast disconnect is
standard.
CEILING COMPATIBILITY
Luminaire is available to t most standard ceiling
types. NEC-compliant T-bar clips supplied with all
grid trim xtures. G trim xtures used in SG ceilings
require T-Bar clip accessory. See ceiling details on
reverse. For hard ceilings order G trim and FK ange
accessory. Assemble then support FK accessory at
ceiling plane using tie wires (by others). Contact
your Columbia representative for compatibility
information for specic ceiling types or for
continuous row applications in hard ceilings.
