A Houseworks innovation has fine-tuned the concept of battery-operated dollhouse lighting! It's 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.
