This light is super cool looking and can change shape. We have used it for about 16 months and it is now not working in 2 out of the 3 layers. It is suppose to have 9000Hrs on it which I figured would be at least 3 years. I called the number on the install paperwork with no response. It seems to be a single persons cell number. Overall very disappointed for what we paid for it. I would not recommend it.
