a Total Harmonic Distortion (THD) <10% and are available in120 or277 volt. Dimming is available with a dimming range of 15% to 100% in 120v only. T5: All ballasts have "end of life" circuit protection, a Total Harmonic Distortion (THD) <10%, a ballast factor of .87 and are available in 120 or 277 volt. Factory installed ballast disconnect allows the ballast to be disconnected from and reconnected to incoming power under load without turning the entire circuit off.

6. Suspension: (not shown) The Multi-Lyte Channel and the Fixture are suspended
