In addition, ULT?s “120V tap“ version has the competitive advantage to also operate a 3-wire “self-heating insulation detector thermal protector,” which generates a significant cost reduction (up to $5 per fixture) for the OEM vs. the 4-wire version. The respective ULT part numbers are 188895.02 (footed), 188896.02 (studs), and 188897.02 (JT3 “120V tap”).
Electronic high-intensity discharge (eHID) ballasts can significantly reduce energy use and monthly operating costs in a broad range of applications such as warehouses, big-box retail stores, factories, manufacturing facilities, schools, and parking lots. All Universal eHID ballasts feature industry-leading intelligence in the form of a microprocessor that continuously monitors lamp characteristics during operation and adjusts the lamp current to optimize lamp performance. They also stabilize lamp color temperature by providing a relatively constant output power, and they provide flicker-free performance throughout the lifespan of the lamp. Additional features include a rugged, lightweight design.
