Sustainable Engineering: More-Efficient Lighting is not Rocket Science

Sustainable Engineering: More-Efficient Lighting is not Rocket Science: "The recent case of a lighting system in a lead-acid battery supplier/recycler shows the kind of energy savings possible without resorting to LELEDs, CFLs, or other superefficient illumination technologies. The battery supplier upgraded the 1970s-era lighting in its 28,000-ft2 facilities using fairly ordinary but modern light systems. For example, 400-W metal halide fixtures in the industrial areas were replaced with 8-ft fixtures containing high-output electronic ballasts and six 4-ft T8 fluorescent lamps at 32 W each.The recent case of a lighting system in a lead-acid battery supplier/recycler shows the kind of energy savings possible without resorting to LELEDs, CFLs, or other superefficient illumination technologies.
