Hi-Lume® 3D ballasts deliver high dimming ratios and efficiency in a slim-profile enclosure, making it a great choice for low-profile architectural fixturesBecause Hi-Lume® 3D is microprocessor-controlled, it can operate on the EcoSytem digital control bus and has the ability to listen, think, decide and remember, this provides a new level of flexibility in configuring lighting while saving energyContinuous, flicker-free dimming from 100% to less than 1% for T8, 1% for T5 and T5-HO and 5% for T5 Twin-tubeProgrammed rapid start design preheats lamp cathodes before applying full arc voltage to enhance lamp lifeLamps turn on to any dimmed level without flashing to full brightnessLow harmonic distortion throughout the entire dimming range maintains power qualityFrequency of operation ensures that ballast does not interfere with infrared devices operating between 38 and 42 kHzInrush current limiting circuitry eliminates circuit breaker tripping, switch arcing, relay failure and component life degradationBallasts maintain consistent light output for different lamp lengths, ensuring fixture uniformityUltra quiet operationProtected from miswires of any input power to control lead, or from lamp leads to each other and ground
