Review on LE LED Flush Mount Ceiling Lights: Dimmable 10 inch Brushed Nickel Fixture, 1200lm 16W (120W Equivalent), Ideal for Kitchen, Bedroom, Laundry, Living Room Hallway - 4000K White by Tiffany Smith

What I wasn't aware of when I bought this device is that once the battery runs out, the device has to be completely replaced. I had it installed by an electrician who does other work in my house, so I didn't know until I asked him if he needed a lightbulb for it. It's wasteful for me and I wouldn't buy it if I knew about it. Supposedly this takes quite a long time, but at the end of its time the entire block will still be in a landfill somewhere. It works well and is very bright, which I really appreciate. However, I wouldn't buy it again due to possible extravagance.
