Reliable performance Vacuum-pressure impregnation is used to re-enforce the electrical insulation of the ballast, preclude moisture, inhibit noise, and dissipate heat, Pre-insulated voltage leads reduce the risk of shock and shrink installation time The basic ballast is the open core and coil which is most often used as a component within a lighting luminaire. The core and coil also forms the nucleus of Philips Advance's five other ballast configurations. Vacuum-pressure impregnated with a silica-filled polyester varnish, All core and coil ballasts below 600W utilize a UL Class H (180ºC) insulation system, C and C ballasts 600W and higher utilize a UL Class N (200ºC) insulation system, Pre-insulated voltage leads, Ballast kits supplied with pre-wired ignitor High bay retail, manufacturing, gymnasiums, warehouses, parking structures, outdoor
