1: Introduction
This High Bay light is designed for illumination of industrial locations. It uses the latest in solid state
lighting technology for long life, low maintenance, and high efficiency.
The unique optical design focuses light downward to where it is needed, giving improved efficiency
over a conventional HID luminaire.
An internal power-factor-corrected switch-mode supply allows it to be used from any nominal 120V-
277V, 50/60Hz AC supply without any variation in light output.
The unit is provided with an occupancy sensor that will switch the light from off to on when motion
is detected. The sensor’s position and detection pattern is adjustable, as well as the length of time
the unit operates at full brightness.
Models HB1C4T, HB1C4S, HB2C1S, HB2C1T, HB2C4T, HB3C4R, HB4C1R, HB5C4T, HB5C4S,
HB6C4T, and HB7C1T are suitable for use in the following locations:
