I just litter flashlights around the house - they range from 300 to 3,000 Lumens. I was going to light up the stairs with string lights but decided not to. We don't have any outlets in the hallway nor on the stairs. The other headache was the Ileostomy bag which I had to hold with one hand which meant that I couldn't use the railing.
The head lamps are good at freeing up a hand. I have an older one that has been very useful on occasion ... like going up into the attic.
