Try an LED flashlight. Bright, and several of mine are 4+ years old, and STILL running on the original generic AAA batteries they came with...
They may not be ready for prime time as HOUSEHOLD lighting, but as flashlights and book-lights, they’re outstanding now...
We got one for a gift. It is not as good as our regular flash lights. We threw it in the back of the junk drawer so we didn’t get it confused with the good ones.
