Overview
Fifth Light’s line of DALI CFL ballasts provide continuous dimming
control and network connectivity to conserve energy, simplify
maintenance and personalize the lighting environment. The
Dimmable CFL Ballast allows for changes to light levels, 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 3%
Variable ballast factor is field programmable to suit project specific
conditions
Programmed rapid start
