It's possible to lose power here during T-storms. To date the longest the power has been out was about six hours. We have had some bad ice storms that disrupted the power for longer terms but luckily not at my house. My approach to light is to have a lot of lights combined with a ton of spare batteries. But I also keep a crapload of beeswax tealight candles as well as a couple cases of liquid paraffin lamp cells (the 8 hour size). I've got a couple of UCCO Mini and Micro candle lanterns that will use the paraffin cells so I'm good on light.

As the torches go I have a fair number of hi lumen "tactical" type lights, a few hi power headlamps and them some lower lumen lights with better runtimes. All of my lights are LED. I have a Pelican Nemo that's only about 65 lumens but it runs for 50 hours of so off of 3 C-cells.
