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 100V-277V,
50/60Hz AC supply without any variation in light output.
A 2 conductor, 18 AWG, plenum-rated cable is provided for dimming control. The cable jacket is red in
color and contains one black conductor and one red conductor. Dimming is controlled by means of a 0-10
VDC signal (to be provided by the installer) to control the level of dimming. At 10 volts, the output of the
unit is 100%; at 0 volts, the output will be approximately 15%. The DC dimming voltage should not
exceed 15 VDC. Increasing the voltage from 10VDC to 15VDC will not result in additional light output.
Models HB1C4X, HB1C4Y, HB1N4X, HB3C4W, HB5C4X, HB5C4Y, and HB6C4Y are suitable for use in
