It depends on the lamp:

• If the lamp has a built-in light source, it is always included.
• If the manufacturer includes bulbs with the lamp, this will be stated in the product description at the bottom of the product page.
• If nothing is mentioned, the lamp does not come with a bulb or light source. However, we do sell bulbs separately, so you can find the perfect match for your lamp. Our recommended bulbs for a given lamp are listed on the product page. Find the bulb you need here.
