This isn't a techno solution nor one that will do anything other than create an ambiance and doesn't flog the horse. I suggest you eat some oranges/tangerines/mandarines and make oil lights with them, and/or buy some candles, and/or oil lamps. (Obviously with all the safety aspects adhered to). You don't need the lights on at all if you are on computers and you don't have to be in the dark without electricity. It can be most beautiful without. Folks managed for years without it. Keep the power for the techno machines and the beauty for yourself.
P.S. using orange lights, put them in a bowl of water, then they don't burn up at the end.
