GENERAL DESCRIPTION
The complete luminaire designated _______ (identify) shall 
be a GE CONSERVA® 400 luminaire, ordering number _______ 
(specify C4S or C4SW, plus ordering number logic from catalog) 
or approved equal to operate one _______ (specify [250 or 400] 
watt high pressure sodium [HPS] or metal halide, or [250 or 
400]watt pulse start metal halide or [400 watt] mercury) lamp 
from a nominal _______ (specify 120, 208, 220, 240, 277, 347 
or 480) volt 60 Hz or (220, 230, 240 or 380) volt 50 Hz power 
source. The luminaire shall include a completely prewired integral ballast and an optical assembly with _______ (specify 1.9, 
2.2 or 2.3 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 [available for 250-watt HPS only]). The 
luminaire shall be UL Listed SUITABLE FOR DAMP OR WET LOCATIONS with specific mounting hardware and C-UL (Canadian) 
Listed for Indoor Locations. Standard construction is IP52.
MECHANICAL CONSTRUCTION
For ease of installation and to facilitate maintenance and 
replacement , the luminaire shall be supplied as components ballast , optical and mounting.
