The lights have been fully installed, perfect. This makes my bar look very atmospheric. I have purchased these lights multiple times, this batch includes 15pcs of 102 meter lights and another 4pcs of 12 meter lights. All the lights work very well. The seller recommends purchasing lights with transformers, which have a safe voltage below 36v and are safer to use. In addition, purchasing remote-controlled lights can be remotely controlled, making it more convenient to use. I will make another purchase.
