LOWMOUNT ® 150 LUMINAIRE

LOW BAY ENCLOSED

GENERAL DESCRIPTION

The complete luminaire designated _______ (identify) shall be
a GE LOWMOUNT® 150 luminaire, ordering number _______
(specify L1M, plus ordering number logic from catalog) or ap­proved equal to operate one _______ (specify [70, 100, 150
(55V) or 250] watt high pressure sodium [HPS] or [175 or 250]
watt metal halide or [175 or 250] watt mercury) lamp from a
nominal _______ (specify 120, 208, 240, 277, 347 or 480) volt
60 Hz or (220, 230, or 240) volt 50 Hz power source. The lumi­naire shall include a completely prewired integral ballast and
an optical assembly with _______ (specify 1.5 or 1.7 accord­ing to photometric selection table) IES Spacing Criterion (SC).
The luminaire shall be suitable for continuous service indoors
in a maximum ambient temperature of _______ (specify 40°C
or 55°C). The luminaire shall be UL Listed SUITABLE FOR DAMP
LOCATIONS and C-UL (Canadian) Listed for Indoor Locations.
Standard construction is IP52. Units with W (Wet Location) op­tion are IP54.

MECHANICAL CONSTRUCTION

For ease of installation and to facilitate maintenance and re­placement, the luminaire shall be supplied as components —
ballast and optical.

The ballast housing and optical assembly shall be provided
with an easy-to-read moisture-proof nameplate that can be
read without disturbing the installed luminaire. All ballasts and
optical assemblies shall include provision for optional field
mounting of safety chains.

The ballast assembly shall include an activated charcoal filter
capable of filtering gaseous and particulate matter. The filter
shall be constructed to permit free passage of air, allowing the
luminaire to breathe during normal off-on heating and cool­ing cycles and therefore eliminating unnecessary stress on the
gasketing.

The ballast housing and structural parts, including mounting
hub, shall be of die-cast aluminum. The ballast housing shall
have an electrocoat gray paint finish.

A heavy duty mogul base socket with superior lamp gripping
shall be mounted to the ballast housing. The socket shall have
the ability to handle the higher pulse ratings of newer HID
systems.

To facilitate mounting, the luminaire shall have separate light­weight mounting components that can be easily
removed from the ballast housing and assembled to the struc­tural or mounting hardware prior to mounting of the remainder
of the luminaire. The mounting devices must provide a positive
vibration-resistant locking means
including a set screw.

The wiring access cover plate and all screws requiring
removal during normal conduit mounting and/or wiring shall
be captive.

BALLAST OPERATION

The luminaire shall contain a standard _______ (specify Mag­Reg or Autoreg) type ballast* in full compliance with lamp-bal­last specifications available to the fixture manufacturer from
the lamp manufacturers at the time of fixture manufacture.

The ballast shall reliably start and operate the lamp in ambi­ent temperatures down to -20°F for mercury or metal halide or

-40°F for HPS.
The luminaire and ballast shall be from the same manufacturer.

OPTICAL ASSEMBLY

Mounting of the optical assembly to the ballast assembly must
be secured by positive vibration-resistant means. The optical
assembly shall be enclosed, gasketed and hinged for easy lamp
access, and shall be removable from the ballast housing with­out tools.

The optical assembly shall be enclosed with a continuous gas­ket .

The refractor shall be _______ (specify UV stabilized injection
molded prismatic heat-resistant special heavy-duty acrylic [for
use with metal halide lamps] or polycarbonate resin) for low
brightness.

The aluminum reflector shall be faceted to provide precise light
control for all high intensity discharge (HID) light sources. It
shall have an Alzak
