Overview
Fifth Light’s line of DALI ballasts provides continuous dimming
control and network connectivity to conserve energy, simplify
maintenance and personalize the lighting environment. The
dimmable electronic ballasts allow for changes to light levels,
program lighting scenes and to detect when a tube needs to be
replaced.
Features
Integrated DALI communication interface (can be run in the same
conduit as power lines)
Available in 120/277 and 347 VAC
Continuous dimming from 100% to 1% for T5, T5HO and T8
based on catalog number shown on this sheet
