D ES C R IPTION
Recessed open downlight with 6 inch aperture for vertical PAR38 medium
base metal halide lamp. Universal input electronic ballast features end of
life shutdown. Fixture is suitable for commercial construction. Insulation
must be kept 3” from top and sides of housing. Lower parabolic shielding
cone with 60° cutoff yields low aperture brightness.
