LED Lights Power Supply

LED Lights Power Supply. The information is on the label on the pics. I know nothing about how they work. We have 42. They were put new in a new construction and then removed before being used due to not being the correct ones. I can bundle up to 5 per package, if you need more you need to do 2 separate purchases and bundle again. I will ship it on the same day if the post office is still open. We iniatially paid $40 for each, asking $15 firm to try to get some of the money back.
