The CHG Series is designed to deliver highly efficient H.I.D. lighting to clean 
areas. These units are ideal for ceiling heights up to 18'. Lower wattages are 
also available for standard 8' to 9' ceilings. Units are enclosed and gasketed 
to protect against the chance of foreign matter entering high tech environ-
ments through the light fixture. The housing and door are designed to work 
with standard 1" and 1 1/2" T-grid ceilings. Door frames feature a gasket 
design which eliminates ledge or crevice exposure preventing the harboring 
or contaminants. These luminaires are U.L. listed and C.S.A. certified for wet 
locations.
