One of the most interesting parts of lighting energy efficiency to me is that once lighting uses so little power, you can use battery backup for power outages.

I'm surprised there isn't a push for low voltage LED lighting. Running low voltage cabling and electrical boxes is a lot easier and the LEDs run off of low voltage anyway. Outside of appliances, who needs 120VAC in most of their rooms?
- dwiel 14y agoI was going to do this in the house that I am building, but the building department has very strict codes for how often you need 120VAC outlets (quite often to prevent daisy chained power strips and similar unsafe behavior). The relevant code is from the International Building Code: "Receptacles shall be installed so that no point measured horizontally along the floor line of any wall space is more than 6 feet (1829 mm), from a receptacle outlet."

- darkarmani 14y agoYeah, that is a common building code requirement in most states. It's going to be more annoying when everything starts having USB plug adapters and charges off 5v.
