Ballast / LED Driver
Ballasts are electronic. They are efficient with a high power factor greater than 90%, and quiet with an “A” sound rating. The LED source is controlled by an advanced electronic driver that delivers consistent power.
Surge Suppressor
All 120V, 277V, and universal voltage LED luminaires are equipped with an integral, 6kV surge suppressor.
The LED dimming option is the 0-10V type, with pulse width modulation (PWM), and current-sinking control.
CF dimming options include the Mark 7 ® (0-10V), Mark 10 ® (line voltage), DALI (addressable), or Ecosystem ®.

Note: Use a current-sinking dimming system (by others) for LED dimming.
The dimming option is not available with 347V systems, or for outdoor CF applications.
Compatibility of this product is not guaranteed with all control systems.

For LED and CF systems, remote emergency back-ups are available, in the standard temperature type; see “Emergency Back-ups for Pendant Lights”.
