100W - 1000W
Lamp Included
The heavy-duty JB Series High Bay is designed for commercial and industrial applications. Its highefficiency reflector delivers consistent high light levels with low glare and little reflector maintenance.
HOUSING/OPTICS Heavy-duty, die cast aluminum housing comes standard in a white polyester powder coating, has heat-dissipating fins to extend ballast life, and is rated at 65°C ambient. Consult factory for other color options. Reflector: The 14”, 16” and 22” aluminum reflectors produce a smooth, even beam pattern with an
80% efficiency rating. The 16” and 22” fixtures can be totally enclosed. Adjustable Distribution: The spring-loaded
Twist-N-Lock™ reflector attachment system allows for complete tool-free reflector installation. Simply pull open the spring-loaded locking pins and snap-lock the reflector in place.
BALLAST The ballast housing has heat-dissipating fins to extend ballast life and is rated at 65°C ambient (see table). All fixtures are supplied with a high power factor high reactance or CWA ballast.
LAMPS The JB Series is available with 100 - 1000W pulse start metal halide, 1000W metal halide, and
250 - 1000W HPS. Open rated fixtures are supplied with restricted sockets and open rated lamps.
MOUNTING OPTIONS A direct hard wire with slide box or hook, cord & plug mounting is available. The slide box has an adjustable hook assembly for fixture balancing.
Also, the easy-access wiring chamber provides additional room for wiring make-up. Optional swivel pendant mount is available.
