SATCO|NUVO's new generation of Type B ballast bypass lamps, designed to replace T8 or T12 medium bi-pin fluorescent lamps, are available in 4 foot lengths in a variety of wattages and lumens. These lamps are engineered for double-ended wiring and will not light unless the ballast is bypassed. Commercial venues, schools, hospitality, health care facilities - virtually any large scale lighting application - will benefit from immediate energy savings and less maintenance. With 347V, these lamps are for use in Canada.
