I'm an electrician. These lights are not safe. I installed 4 bulbs in the kitchen, I had to build a junction box as it was not included in the kit. After installing I followed the sync steps with T and they never showed up. So I started playing around with the wires and noticed they were very hot 10 minutes after I flipped the switch. I'm glad I cleaned all the insulation because I'm sure the house would have caught fire. I quickly removed them and sent them back. I wouldn't buy it, not worth the insurance claim.
