For personal lighting, we are spoiled for options these days. LED headlamps are great for moving around the house. They put light exactly where you need it, rather than trying to illuminate every room. You can find 2- or 3-packs of them at any big-box store (Walmart, Lowes, Home Depot etc). Ditto for LED lanterns; every big-box store sells them. They can often run 24-36 hours on low mode. You can pay top dollar for a full-featured camping lantern, or get some cheap ones and buy a few for redundancy. LED puck lights are handy to stick in closets or other places you need a little extra light during a blackout (i.e. bathrooms, closets, circuit panel). The cheap ones are touch-activated, the nicer ones are motion-sensing. For all of the above, there are often rechargeable versions that you can charge with USB (the same way you charge your phone). The nice thing with this, is that you can keep all of that stuff (and your phone) topped off with a USB power bank, instead of fishing around for spare batteries. I would pick 20000mAh for the power bank. For reference, a 10000mAh power bank will charge an average smartphone from empty to full twice. We have a mix of all of the above, with batteries we buy in bulk from Costco or Amazon every so often.
