Unlike any other manufacturer, direct retrofitting with electronic ballasts rated for T8 and T12 fluorescent lamps directly replaces existing T12 HO lamps with up to 25% greater efficiency! Whether you are building, designing or retrofitting an existing sign, you'll find it easy to incorporate TriLight Max into your signage program. Unlike other manufacturers that specialize in general lighting, Voltarc lamps are built with the sign-maker and professional serviceman in mind and are made to the same industry lengths as standard T12 high output lamps.
