Control fluorescent light levels in your rooms with Lutron DVF-103P-277 Diva single-pole/3-way dimmers. As its name implies, this is the dimmer that you will use to control your fluorescent lighting if your system is on single-pole wiring or 3-way wiring. If you are on a 3-way system, only one switch can be replaced with a dimmer. Note that DVF-103P dimmers are for use with Hi-lume, Hi-lume 3D and EcoSystem ballasts and Hi-lume A-Series LED drivers. Additionally, the fluorescents must be 277V 8A lamps.
