Bulbs are not replaceable on miniature battery operated lights but they will last around 4000 hours of "on" time. They produce much less heat than regular dollhouse wired bulbs but still should not be left on for long periods of time (many hours) because the small amount of heat they do produce can over heat some of the tiny wiring and damage the fixture.
Nice bright light
Works great for what I need!
