Philips Advance PowerSpec HDF254T535M 120-277V Outdoor Dimming T5HO Ballast Operates the Following Fluorescent Lamps:\u00a0 (2) F54T5 HO\u00a0 (2) FT55W\/2G11\/RS –\u00a0 (1) FC12T5 HO\u00a0 55W Circline\u00a0\u00a0 IntelliVolt Technology 120-277V 50\/60Hz Additional Information: Low Profile Design (Dim: 16.7\u201dL x 1.18\u201dW x 1\u201dH.) General Specifications PowerSpec HDF Fluorescent Dimming Ballasts provide high performance, full range dimming of linear and compact fluorescent light sources and are ideal for aesthetic and architectural dimming in residential and commercial spaces, as well as energy-oriented applications. PowerSpec HDF Ballasts incorporate stringent quality assurance including robust electronic components, protective circuitry, surge protection, and testing\/calibration. The PowerSpec HDF Ballast achieves its outstanding performance by incorporating a unique electronic feedback circuit. This circuit monitors the lamp performance and continuously corrects the current input and cathode voltage to achieve consistent, smooth, flicker-free operation. In addition, they are protected by Lightolier\u2019s exclusive, single-source three-year warranty, which covers the Dimming Controls, PowerSpec HDF Ballasts, and Lightolier fixtures. PowerSpec HDF Ballasts dim linear T-8 and T-5 fluorescent lamps smoothly and continuously to 1% of full lumen output, compact T-5 and T-4 fluorescent lamps smoothly and continuous to 3% of full lumen output. While in operation there is no perceived difference between the light levels of one- and two-lamp ballasts for the same type of lamp. The system consists of Lightolier PowerSpec HDF electronic dimming ballasts, an interface (where applicable), and controls, all connected by standard three-conductor line voltage wiring (hot, neutral, and signal within the same conduit). PowerSpec HDF Ballasts turn on to any set intensity, even absolute low, therefore making the system perfectly suited to preset dimming controls. PowerSpec HDF Ballasts also feature a soft-start circuit that prolongs lamp life. All T-4 and T-5 ballasts contain a Lightolier Controls lamp fault interrupter circuit that helps prevent overheating or abnormal end of lamp life conditions. All PowerSpec HDF ballasts are U.L. and CSA-listed for both 120V & 277V, 50Hz or 60Hz, and comply with FCC Part 18C guidelines<\/p>\n","protected":false},"excerpt":{"rendered":"
