Half-Light Ballast Controller: for Use with 4-Lamp Fixtures

The Two Stage Half-Light® (HAF2) is designed for a 2-ballast, 4 lamp fixture where each ballast controls two lamps. Within this configuration, an initial toggle “on” of the wall switch activates only one ballast to produce 50% light; by toggling the switch “off” then “on” again, both ballasts will be activated to deliver full light output. The sequence can be easily restarted by holding the switch in the “off” mode for at least 5 seconds.
