Universal Lighting Technologies S150MLTLC3M-500K High Pressure Sodium Magnetic Ballast

The Universal Lighting Technologies S150MLTLC3M-500K is a magnetic core-and-coil ballast designed to start and regulate current for a single 150W High Pressure Sodium lamp in commercial and industrial HID lighting systems. It operates with input voltages of 120/208/240/277 VAC at 60 Hz and uses pulse-start ignition to deliver reliable lamp starting and consistent output, guided by a High Reactance / High Power Factor (HX-HPF) circuit. The unit is supplied as a replacement kit with prewired components for straightforward installation, including the ballast, capacitor, ignitor, and mounting hardware, and features color-coded leads for easier connections in fixture-mounted installations. UL Listed and CSA Certified, the unit is commonly used in warehouses, factories, parking lots, security lighting, and outdoor area lighting; common replacements include Philips Advance 71A67D2-001D HPS Ballast, Universal Lighting S150ML5AC3M, and Venture Lighting 150W HPS Magnetic Ballast Kit. Designed as a fixture-mounted magnetic ballast, its pulse-start operation, 60 Hz, and HX-HPF configuration support stable operation across common commercial lighting installations.
