This lamp came with a large semi circle piece of glass that was supposed to sit on the inside of the shade to diffuse the light from what may be a harsh lightbulb but the semi circle piece of glass did not sit secure inside the shade. My husband was devastated but loved the lamp so much he didn’t want to go through the hassle of returning it and then reordering so we just kept it as is and use the lamp without the insert over the lightbulb. It’s not too much light and it seems to be fine. Also it’s worth noting that the head of the lamp (the shade) does not swivel 360, it simply tilts up and down
