Mike Jay wrote:Hi Ruth, if I can read into your question a bit more, I "think" you might be wondering about using smaller wire gauge in your wiring circuit since LEDs don't draw much current. I've wondered if some day they will change the electrical code in the US to allow for smaller wires on lighting circuits. But for now, as far as I know, lighting circuits still need to use wire sized to handle incandescent sized loads. Typically 15 amp circuits with 14 gauge wire.

DC is much easier to work with in electronics, there is always power available, unlike in AC where power needs to be stored for 10ms (a long time in electronics, modern regulators go up to the MHz range).
All that remains is to figure out the voltage, connector and data protocol…

More than anything else - LED lighting refers to the type of lamp that you will use, in place of other lamps that are available (incandescent, fluorescent, halogen, etc). For normal residential lighting needs, wiring your home in compliance with NEC (National Electrical Code) and local building codes will provide you with everything you will need to install LED lighting. Nothing needs to be done any differently.

Having said that - there is the potential for "flickering". ...
There are electronic devices that can be installed, designed to increase the frequency of the power to as much as 150 hz. The higher frequency reduces the noticeable flicker.

CFLs not only have mercury, less light than incandescents, don't last as long as advertised - but they have a deep blue spectrum. Using this at night fakes your body into thinking it is still daylight out - and so your melatonin and sleep cycle becomes disrupted.
The light CLOSEST to actual sunlight IS the incandescent. So-called "full spectrum" and grow lights miss significant portions of the light spectrum (worse than incandescents) and have huge spikes at other frequencies. Look up Dinshah...
Use them of course, in moderation - but keep yourself in the sun because i think we are humanly solar powered to greater degree than we'd thought.

I'm also building a house and what my wife and I are doing is wiring it traditionally for 110v AC circuits and we are going to simply screw in LED bulbs everywhere. It can be that simple, with no need for hybrid AC/DC anything. It's certainly one way to go about it.
It sure was nice of your sister to lend us her car. Let's show our appreciation by sharing this tiny ad:
