I'm participating in an art show soon in which I am making "sculptural light paintings" of which require a few 12v LED strips. They're the kind that work in aquariums and car's taillights and whatnot, and look like this;
I have about 3-6 lights being used per sculpture. So far my idea is to solder each one of them to an individual battery pack (so 3-6 battery packs per sculpture) that holds an A23 12 volt battery, and then connect each battery pack to a communal switch to turn all lights on and off at a whim to conserve energy. The LED strips vary in length (despite all being 12v) ranging from 20 inches long to 6 inches long.
As this is an art show, I prefer to not have any kind of outlet going into the wall as it really takes away from the look of the work, hence the battery packs. That being said, i also need the LEDS to be reliably powered for 2 weeks and active from 9-5 each day. Do you all think that this may be possible or will a different energy source be more efficient?
So far i have a test led strip lit up via 12 volt A23 battery that has been going for about 2 days now with no problems, but that's my only finding. I'm quite lost as I know this will all work in theory, but I'm not sure it's reliable in duration.
