I'm OCD about house lighting, mainly because I get, "Did you hear that sound?" from MrsWD just before she dives the covers and holds a pillow over her head.
The biggest thing for me is keeping the lights in designated places so I can find them in an emergency. I try to keep the NEBO rechargeable plugged into the charger on the kitchen counter all the time. (I don't have a lot of luck with that.) It's strong enough to let me see the chicken coop 75 yards away. The little Fenix PD 35 is small enough to keep in my desk drawer and is strong for its size. The contacts need to be cleaned every few months though. It takes 123 size batteries.
I've tried a couple of headlights and like this "Coast" brand from the hardware store best. It uses 3 AAA batteries that last about an hour at full power. I keep an extra set of Eneloops on the battery maintainer and swap them out when they get weak. I like this better than the rechargeable headlamp I have because when its battery is dead I'm dead in the water until it is charged.
We have motion sensing lights in every room. We have plug-ins where there is an appropriate outlet and some are battery powered ones for places there is no outlet.
Our biggest problem is location discipline. I'd railed and railed to MrsWD about the putting the damn flashlights back where they belong, and I still find myself searching for one when I need it.
