PHILIPS ELECTRONICS -LIGHT 498790 Ballast electronic parallel 4-lamp high light output 120-277V 32W

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.
