It does not come with a bulb despite the description. I brought this up with Wayfair and the rep said they would send me a bulb. However, Wayfair later cancelled the bulb delivery saying it’s not supposed to come with a bulb despite the description.  It has a 3-way switch so if you buy a 3-way bulb, it will switch from low, med, high and off. As others have complained and as shown in the pic, you can easily see the bulb from the top. It’s an A19 bulb in the pic.  You can try a lower profile bulb like an A15 which may help a little.  However, I was not able to find an A15 with 3-way capability.
