Lutron EC3DT418KU2S 3WECO EcoSystem® 3D Fluorescent Ballast; 120/220/240/277 Volt, 41.1 Watt At 120 Volt, 39.6 Watt At 220 Volt, 39.4 Watt At 240 Volt, 39.9 Watt At 277 Volt, 2-Lamp, Programmed Rapid Start

Detailed Description: Lutron EcoSystem® 3D Compact studded dimming ballast has a voltage rating of 120/220/240/277 Volts. Ballast is compatible with T4 4-Pin quad-tube or triple tube and can operate two lamps of power rating 18 Watts. A-rated ballast operates silently and has a ballast factor of 0.95. Energy efficient ballast incorporates inrush current limiting circuitry to prevent circuit breaker tripping, switch arcing and relay failure. It features programmed starting method that ensures long lamp life. It maesures 4.900 Inch x 1 Inch.

Dimming ballast provides uniform lighting and is ideal for all industrial applications. Ballast features flicker-free dimming from 100% to 5% for T4 lamps. Ballast offers wide range of dimming level without going to full brightness. It has very low harmonic distortion throughout the entire dimming range and maintains consistent light output for different lamp lengths. Ballast incorporates end of life protection circuitry that ensures safe operation. Ballast is ideal for all general lighting fluorescent applications. The case has a temperature rating 75 deg C. Ballast is grounded by a mounting screw to the fixture. Ballast has high power factor greater than 0.95. Ballast is UL listed and CSA certified.
