I bought a total of 40 spots in 3 orders. 30x 9W and 10x 12W. 2 spots were missing in the first delivery. So I had to order 10 extra pieces. I needed them quickly so I paid for them myself. 1 spot flickered and 5 spots were immediately defective when I connected a drill to the circuit. So I had to swap these spots too. So in the end I paid for 40 pieces but I could only use 32. Quality equals price. Wires very thin. Brightness good.
One was damaged - let’s see
I am losing the LED spots one by one after 1-2 month - they are getting too hot & after a while they turn off / are damaged .
