The lamp base is made of sturdy metal

Approximately 16 (height) x 10 (width) in inches.

A metal plate was rolled in to make the body of the lamp base

It uses a standard light bulb - A15 LED bulb, which is about 3-inch tall and available at Home Depot, big grocery chains, and online. We DON'T recommend the incandescent bulb due to the excessive heat produced.

This durable desk lamp will last for a long time. And its quality is absolutely superb.
