I had no idea this cabinet had a light in it. It is so cool .The top section has the light which is very bright and the glass shelving goes in that area. It must be plugged in to work . When you open the door , the light comes on . Very unique.  I needed a small storage cabinet for my small bathroom . I did a video of it to post, I liked it so much. So far it’s working out great. We have high moisture in there at times so I’m hoping it will hold up to that . It seems very well made. Instructions were easy to follow. I would purchase again.
