Testing of energy conservation of electronic ballasts for fluorescent lighting. Review of recent results and recommendations for design goals

Conference ·
OSTI ID:6521051
The performance of two 40-watt T-12 fluorescent lamps driven by both standard core-coil, and electronic ballasts has been measured over a range of temperatures and input voltages that simulate conditions they would experience in typical building installations. When using new energy-efficient lamps and electronic ballasts, an efficiency of 90 lumens/watt has been achieved, which represents an efficiency improvement of over 37% relative to standard lamps and core-coil ballasts. From these results, several design targets are suggested for ballast developers. Additional features of the electronic ballasts, (low noise, no flicker, and light level control), have potential to increase the use of efficient light sources (gas discharge types) as well as permit less costly luminaire construction. The dimming feature should also conserve energy whenever applied.
