The BA-E36122 is a two lamp electronic ballast which replaces the BA-E3612. This constant current ballast will only operate if both lamps are firing, and will shut itself down after a one minute period if one lamp happens to fail. The BA-E36122 operates from 100-250V/50-60Hz and fires 36" lamps only.
