GENERAL DESCRIPTION
NUVATION
™
INDUSTRIAL LUMINAIRE
UNIMOUNT
®
400
The complete luminaire designated ____________(identify) shall
be a GE - “UME” UNIMOUNT
®
400 luminaire, ordering num-
ber_________ (specify UME, plus ordering number logic from
catalog) or approved equal, to operate one _________(specify
[250, 320, 350 or 400] watt pulse start metal halide or [250,
320, 350 or 400] ceramic metal halide lamp from a line voltage
range between 208 and 277 volts with a +/- 10% line voltage
tolerance, 50/60 Hz and will automatically sense voltage within
specified range.
The luminaire shall include a completely prewired integral elec-
tronic ballast and an optical assembly with ________(specify
1.4, 1.6, 1.7, 1.9 or 2.0 according to photometric selection table)
IES Spacing Criterion (SC). The luminaire shall be suitable for
continuous service indoors in a maximum ambient temperature
of 55°C. The luminaire shall be UL Listed SUITABLE FOR DAMP
LOCATIONS. UL Listed for metal halide lamps in polymeric lamp
containment barriers. UL Listed for metal halide lamps in poly-
meric lamp containment barriers. 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 shall be provided with easy-to read- mois-
ture-resistant nameplates, which can be seen without disturb-
ing the installed luminaire. All ballast and optical assemblies
shall include provisions for optional field mounting safety
chains.
The ballast housing shall be made out of die-cast aluminum.
The ballast housing and adapter box shall have a white polyes-
ter paint finish.
To facilitate mounting, the luminaire shall have separate light-
weight, slide-on adapter box that can be easily removed from
the ballast housing and assembled to the structural or mount-
ing hardware prior to mounting of the remainder of the lumi-
naire. The slide-on mounting adapter box shall have provision
for ¾ inch pendant mounting with through feed capability and
include easy access wiring box cover plates.
BALLAST OPERATION
See Nuvation Electronic Ballast Spec for specific specs.
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 and gasketed. The re-
fractor shall be _______ (specify UV stabilized injection molded
prismatic heat-resistant acrylic, ST acrylic or LEXAN polycar-
bonate for low brightness. It shall be hinged and latched for
lamp access and no-tool relamping. The stainless spring steel
door latches shall be over-center, vibration-resistant type pro-
viding a spring-like clamping action to the gasket.
The large diameter optical assembly shall dissipate heat and
provide precise light control for all high intensity
discharge (HID) light sources. The textured aluminum reflector
shall have an Alzak
✝
finish on all surfaces (U4M) or the inside of
the reflector shall be painted white (U4MW).
