My house lighting is all LED total wattage with all on is less than

coming up. Not worried about heat or the fridge, I have gas heater

backup and not enough in the fridge to worry about. Are there

approved ways of connecting in the UPS that does not involve adding a

transfer switch. I was thinking about doing this with outlets and

plugs so I could unplug the light circuit and plug it into the UPS.

The easiest thing to do is to run a low voltage lighting system using a

12vdc power system and battery charger. A relay to switch on the 12 volt

LED lights when the power fails is simple to implement and with a proper

low current fuse is quite safe. I bought a little 48 LED light panel

meant to replace an automobile dome light from Amazon to play with and

it and it puts out a surprising amount of light. The LED panel

measures 1-1/2" X 2-5/8" and has double stick foam on the back so it can

be mounted easily. I imagine you can make your own panel using 4 to 6of

them and light up a room very well. I haven't measured the current draw

on it but I found it is quite bright off a 9 volt battery. Low voltage

wire such as telephone wire installed with a stapler could be used to

wire rooms for emergency light using the little modules. ^_^



I think you'll find that telephone wire is probably not rated for use
in a low voltage lighting system in a house. There is NEC that
applies to those types of installations too.
