duhhhhh ~ why didn't I think of this one........
I have a friend who used her solar lights inside at night when her current was off during the hurricane. She stuck them in a jar or bottle and said they gave off plenty of 'free light'. She put one in each room and would put them back outside in the daytime and bring them in at night as long as the current was off. They are safe to use and cheaper than batteries. Bring in a solar light one night and test it.
Due to a thunderstorm, we lost power for about 5 hours. We were scrambling around in the darkness, looking for matches, candles, flashlights, etc. We looked outside, and noticed our solar lights shining brightly all around our patio, stairs, dock, etc. They were beautiful. My wife walked outside, and brought several of the solar lights inside.
We stuck the solar light pipes into plastic drink bottles containers and they made the nicest, brightest, safest, lighting you could ever imagine.
We put one in the bathroom, the kitchen, the living room, etc. There was plenty of light. There are all types of solar lights available. We bought ours at Harbor Freight. We put them all around our yard. They look nice and they do not attract flying bugs like the outdoor lights around our doorway.
The lights we have fit into the small (20 oz) water bottles and they also fit into most of the larger liter bottles. If you need a weight in the plastic bottle to keep them from tipping over, you can put a few of the pretty colorful "flat marbles" that they put in aquariums, and vases. (you can also use sand, aquarium gravel, etc., whatever you have available).
The lights we have were perfect inside our home. They burn all night long if you need them.
The next day, you just take your solar lights back outside and they will instantly recharge and be ready for you to use again any time you need them.
Perfect for power outages, hurricanes, etc.
I never thought of it, and now you don't have to. -----
