The older, traditional main-frequency ballast can consume up to 20-25% of the total lamp current. A modern electronic ballast working at high frequency consumes about 30% less current, and can be used to regulate or dim the lamp output.’<br /> <br /> = Find out more =<br /> <br /> === Related articles on Designing Buildings Wiki ===<br /> <br /> * Colour appearance.<br /> * Daylight benefits in healthcare buildings.<br /> * Daylight factor.<br /> * Daylight lighting systems.<br /> * Dichroic reflector.<br /> * Discharge lamp.<br /> * Extra-low voltage lamps.<br /> * General lighting v task lighting.<br /> * Illuminance.<br /> * Lamp efficacy.<br /> * Light pollution.<br /> * Lighting energy numeric indicator LENI.<br /> * Lighting of construction sites.<br /> * Luminaire efficacy.<br /> * Rights to light.<br /> <br /> [[Category:Products_/_components]]</div>
