• The 350-watt unit delivers power with no interruption to the HID arch, making it ideal for
outdoor and high-bay applications as well as LED and Fluorescent luminaires
Compatible with LC&D® emergency shunt relay dimming and switching systems as well as
Sensor Switch® nLight™ relay packs – integrating normal dimming and control into luminaires
that provide full light output in emergency.
