    • … lighting systems run on DC which means that they can be run even when the mains fails. Low voltage lamps are available in the market. You can choose incandescent lamps if you like. But incandescent lamps are very energy-hungry. It is better that you go in for high efficiency lamps like the latest LED …

    • … as emergency lighting. Our tunnel fixture installed with AMERICAN induction lamp will switch to DC power immediately and keep the tunnel lit as if nothing has happened. Another advantage induction lighting has over metal halide is lumen maintenance. Most significantly, at 40% of service life, metal halide’s …

    • … that can harm us. Hence your low voltage outdoor lighting system is absolutely safe. The outdoor lighting system is supplied low voltage electrical power by a transformer that steps down the high voltage of 120 volts from the mains supply to a safe and low 12 volts. Some outdoor lighting systems run on DC …

    • … your electric toothbrush, clock radio, and so on. LED lighting is on the way and it doesn’t need 120 volts AC either. Right now we solve that problem with dozens of small transformers, aka wall warts. Now there is an effort underway to create a low-voltage DC w Share and Enjoy: These icons link …

    • … and all the waste heat that it generates. One group pushing for DC is called the EMerge Alliance. Their goal is to create standards that will give building designers the chance to put low voltage, DC power supplies in their buildings. They like the idea of designing buildings with, say, rooftop solar …

    • It’s really just for a margin of safety. I’m assuming 19Vac rms, which will have a peak of around 27V. That’ll be the (unloaded) dc voltage you get. I imagine it’ll drop a bit when the lights come on, but your cap will be spending a bit of time with that voltage across it, and it’s just nice …
