Satco's new generation of Type B ballast bypass lamps, assembled in the USA and designed to replace T8 or T12 medium bi-pin fluorescent lamps, are available in 2-foot, 3-foot, and 4-foot lengths. They are engineered for single or double-ended wiring options and will not light unless the ballast is bypassed.
