Black striped interior perimeter of body eliminates light leak

Symmetrical distribution Asymmetrical distribution

The footcandle readings of a typical 8' x 12' pattern layout of 8, 6 lamp units, illustrates that the asymmetric distri- bution adds 35% more light to the operating area (room size 12'

x 16' x 9' ceiling.

A silver grid printed on the back of the asymmetric lens, grounded to the fix- ture,

prevents RFI interference with other equipment.

To prevent any EMI leakage, the hous- ing is sealed and the lens frame is fully gasketed.

F Type fixtures cannot butt together end to side. A space is required between fixtures (See diagrams below).
