We have a pendant light in our shower stall - it had a cheap off-white plastic cover that protruded about 1.5 inches below the ceiling surface and was translucent so the light was diffused. . This cover is easy to install, sits flush with the ceiling and the glass lens instead of a cheap opaque plastic diffuser is cool - it gets more light through, looks sleek and is easier to clean as it sits flush (my wife keeps coming back to it knocked the old cover, which protruded below the ceiling line and cracked). Old piece of shit - this stylish and attractive upgrade.
