Limited applications for indirect MH lighting. No widespread applications. CFL and FL for storage areas. Align F40 or F96 with aisles for effective lighting. Excellent for storage areas, with ceilings over 14 feet.
Many opportunities exist to improve the efficiency of a lighting system.
You can save lighting energy by selecting an efficient lamp and ballast combination and matching lighting usage more closely to user needs through controls. Efficient Lamps and Ballasts You can create an efficient lighting system by choosing a high efficacy source appropriate for the application, determining the level of illumination needed in an area, and then choosing the lamp and ballast that will provide it using the lowest wattage. An efficient light source must also be matched to its application in scale, light quality, and fixture type. CFLs offer an excellent alternative to incandescents in small areas like hallways and lobbies with low-ceilings. CFLs use 60 to 75 percent less energy and last ten times as long as incandescents.
