The other day a spring storm came through around 4pm. Lots of thunder and lightening which scares my son. I OTOH enjoyed it from the comfort of my hot tub out back. Hot water sloshing me on the outside, warm bourbon sloshing me on the inside.
I walked in about 30 minutes after it started and my son had collect a half dozen flashlights, a brick of 50 tea lights shrink wrapped, and his PERSONAL stash of chem lights from his room (about 8), and put them all on the kitchen table in case the power went out.
We are prepared for no lights.
Also a quick tip. I don't mind buying those larger, plastic, cheap 6 volt block batteries you find at the check out at big box stores. I have found that if you use them, then let them sit, they drain. So when not in use, turn the battery over or add a cardboard shim to cover the coils, and put a piece of blue painters tape over the lens & write that the battery is good just disabled and depending on the technique you used how to put it back into service. It will save you some grief.
