Light level switching
By Staff -- Plant Engineering, 1/1/2007
Ballastar T5 ballasts are for use with F28T5 lamps and provide an increase in efficiency of nearly 8% more than standard T5 ballasts. A single control lead allows the user to switch from full light output to 50% power level with a standard wall switch or lighting relay. The Ballastar light-level switching ballast is available with a ballast factor of 0.95, and it also features programmed start technology for long lamp life, universal input voltage (120 to 277 V), and end-of-lamp life shutdown circuitry with auto-reset, The ballasts are suitable for offices, classrooms, conference rooms and other applications where the need to switch light levels is required or desired.
