I have been trying to find a light fixture with a battery backup to use in a storm shelter. I would like to have a light that would continue to operate even if the power goes out. Does not have to be extremely bright because it is a small room, 6x6. I don't think it would be that difficult to make one, but would think there would be a off the shelf item available.
I assume I could take a 12v power adapter, a 12v battery pack and some 12v LED lights together and it would work, but It would be nice to have a manufactured version instead of a cluster of wiring mess.
So does anyone know of a light that I can use off of 110 until the power goes out, then it switch over to a backup battery?
