Is it a feasable idea to have a reading lamp powered by batteries?

A:
Certainly. You can buy battery-powered  LED reading lamps. It would be much less practical to do that with incandescent bulbs, because they require too much power. Fluorescent lamps are also a bit less practical because they require some additional circuitry.
