MAKE FLUORESCENT LIGHTING MORE EFFICIENTThe EnerLume-EM from Enerlume Energy Management Corp. ensures a ballast draws power for lighting only when it is most efficient. It does this by timing when a ballast is on the sine-wave cycle. This device, used for new and existing fluorescent lighting systems, reduces energy consumption by about 15 percent without loss of light. (203) 848-2339; www.enerlume.com
