This well designed, high-quality brass/metal lamp has a smaller battery case which unscrews to access a smaller battery. The 3V lithium battery which is included is replaceable with #2300. The 3V lithium battery will last approximately 50 hours. The LED is not replaceable but will burn for about 4,000 hours and put out much less heat than traditional bulbs. The Bentham Tulip Table Lamp has a nickel finish base with a frosted glass shade.
