Optics and Applications
Twin tube CBs use a two reflector system. The upper reflector is formed and faceted. The pattern is slightly asymmetric depending upon measurement parallel or perpendicular to the lamps. Use in corridors, transit areas, open spaces, foyers, restrooms: anywhere a minimum depth low level shielded source is required.
Design Features
A rigid steel housing protects the optical system. CB cone assemblies adjust 10° each way from below for alignment of baffles with adjacent units after installation. Maximum ceiling thickness 3/4". Ballast and lamp service from below.
Finish
A specular clear Alzak trim is standard. Optional colors and Softglow® finishes are available. The housing and all structural parts are phosphated for corrosion resistance before being painted optical matte black for control of stray light leaks.
Ballasts
Magnetic, encased and potted with class P thermal protection. Thermosetting silica fill for rapid heat dissipation. Minimum starting temperature 32°F (0°C). Ballast factor 1.0, THD <30%.
General
Fixtures are pre-wired, UL and C-UL listed for eight wire 75°C branch circuit wiring. Union made IBEW. Luminaire Efficiency Rating (LER) data is in the photometric directory located in Section Z.
