Lighting Controller 1. Dimming control of fluorescent lamps, mercury lamps and metal halide lamps. • More than 40% electric power saving compared with NO MERS systems. 2. Replace mercury lamp with metal halide lamp with MERS metal halide controller. • Approx. 40% electric power saving compared with NO MERS mercury lamp systems. (from Titech experiment) 3. Intelligent dimming control of lamps with MERS, sensors and Constraint Technology. • Significant saving can be expected compared with existing systems according to QOS
