Universal Lighting Technologies ("Universal") offers a wide array of ballasts for High Intensity Discharge (HID) lamps. Applications include Metal Halide (MH), Pulse Start Metal Halide (PSMH) and high pressure Sodium (HPS) lamps ranging from 35 to 1500 watts. We're the technology leader in every category of HID ballasts. Our Universal Precise line is the latest innovation in magnetic core & coil technology in years. Core & coil ballasts are used in over 90% of all HID fixtures. Universal's core & coil models are available for all HID lamp types, including single-, dual-, tri-, quad- and multi-volt designs. For added versatility and reduced inventory costs, Universal has also introduced the industry's first Multi-5™ ballast (120, 208, 240, 277, or 480 V), featuring a 480 V tap on a conventional quad tap ballast. Universal's Universal Precise is the next generation in core & coil technology, featuring a smaller, lightweight design and improved temperature performance. Universal Precise fits virtually all applications and has no exposed live metal parts. There are no plastic extrusions, which prevents breakage during shipping. Color-coded leads make installation easy.
