High intensity discharge (HID) solid state ballast program: Phase I. Final report
High-pressure sodium lamps operated at high frequency with solid-state ballasts are compared to the same lamps operated at 60 HZ with conventional core-coil ballasts. The major improvements that the solid-state ballasts show include a 20% increase in system efficacy and a regulated, constant wattage input to the lamps. In addition, the solid-state ballasts can safely dim the HPS lamps over a wide range of light levels. Assuming these improvements, these HPS systems may consume as much as 50% less energy than core-coil systems. Background and history, the program plan, performance characteristics, an energy loss analysis, and a market potential study are presented. Task V is stated as involving constructing, testing, and packaging suitably reliable, representative, engineering protype ballasts, and delivering 6 of the units to LBL. LBL will submit these units to an independent test laboratory to verify the electrical and photometric performance.
