Technical Data
Socket Bars: 0.036” pre-painted cold-rolled
steel. Prepunched for lampholders and wire
passageway. Tabs on socket bars securely
mount the reflector in the correct position
relative to the lamps. Note: ESI’s optional
uni-bracket is pictured in the diagrams.
Reflector: The reflector can be ordered with an
85% reflective anodized finish, a 95% reflective
enhanced or film finish, or a 92% reflective white
enamel. The substrate is 0.020” high quality aluminum. The reflector profile is optimized using
computer analysis and manufactured using state
of the art CNC equipment. A protective premask
is applied to all reflective surfaces prior to manufacture.
Installation: For retrofit, the existing ballast and socket
bars are removed. With the new ballast and accessories
installed, the ESI socket bars are centered at the ends
of the fixture and fastened with two self-tapping screws.
The reflector is positioned between the socket bars. By
applying slight compression to the reflector peak, the
tabs on the socket bar are aligned with the punchouts in
the reflector. When the compression is released, the
tabs securely hold the reflector in place.
