PHILIPS ELECTRONICS -LIGHT PHIGEL4P32RHTPM Ballast Reduced Harmonic, Parallel, Thermal Protected 4 Lamps 32 W Standard Electronic Lamps 347 V,

High frequency electronic ballast with parallel and 4-lamp. It offers enhanced lighting performance and energy savings. The Electric Power Research Institute estimates that lighting consumes 20 to 25% of all electric power and that lighting energy accounts for 40% of the average commercial electric bill. The retrofit of existing facilities with modern lighting systems increases productivity and can save over one-half the energy of the original system.
