| Summary: | Until now, electrical energy consumption for lighting by around 15% of the entire world's
electrical energy consumption. Lighting load includes household applications, offices, business
and industry, approximately 80% of its form fluorescent lamp or tube lamps (TL). This type of
lighting is more widely used because of the power used is relatively small compared with the light
bulb (incandescent). Additionally TL lamps are also cooler than incandescent bulb with the same
power consumption. Problem associated with this type of lamp is how to regulate the intensity of
the light it produces. This study aims to regulate the intensity of TL light, so it can reduce electric
power consumption in line with the electrical energy savings. Magnetic energy recovery switch
(MERS) is used to control the lamp voltage in order to control the light intensity as a dimmer. The
switch is mounted in series to compensate for voltage drop due to an inductive component in the
form of ballast. The results showed that MERS can be used as a fluorescent lamp dimmer. Light
intensity settings done by controlling the charging and discharge the capacitor of MERS.
