Advance RMH20KBLSM e-Vision® Electronic Low Frequency Metal Halide Ballast, Metal Halide Lamp, 22 W, 120 VAC

Low frequency electronic HID ballasts such as the Advance e-Vision line constantly measure and adjust the wattage, optimizing delivery of the ceramic lamps' superior color properties. This makes ceramic metal halide operated by e-Vision ballasts the premier choice for many applications previously illuminated by either tungsten halogen or incandescent sources, such as retail lighting.
