Luminaire With Globe and Without Guard
NOTE: Photometric data was
developed using a 100 watt
diffuse mercury vapor lamp
(4,200 lumens). For other
diffuse lamps, use the following
conversion factors (multipliers):
175W MV – 2.05; 70W MH –
1.33; 100W MH – 1.85; 175W
MH (metal halide) – 3.33.
Multipliers are for use with
candela curve only.
Luminaire spacing ratio is 1.30.
