Design Data

Design data on page 26 is for a 44,000-

lumen 400-watt metal halide pulse start lamp

in a medium dirt environment after 8,000

hours of operation (40% of the 20,000-hour

rated life) at an average of 10 hours per start.

The ballast is NuVation

TM

Electronic HID.

In gymnasium applications, GE recommends

flexible mounting on a hook and loop to

minimize the risk of damage if a luminaire is

struck by a moving ball. Safety chains

should be used for each ballast housing and

for each optical assembly.

Gymnasium Lighting with

Versabeam Luminaires

The enclosed and gasketed GE Versabeam

Luminaire projects light efficiently to both

horizontal and vertical planes, with more

downward efficiency than other luminaires

intended for low to medium mounting

heights. This attractive luminaire offers low

glare, but with enough uplight for acceptable

ceiling brightness. The rugged acrylic

refractor is impact resistant. The luminaire

may be remotely ballasted.
