Received 2 "versions". They are the same except the way the 5050 led is driven and the shape of the pcb.
Round pcb is connecting the 3 led's inside in series and the square in parallel. This makes a lot of difference in power consumption. Series one is about 0.15W@12V and the parallel one 0.5W@12V without extra light output.
The one with the round pcb (not the square as in the pictures) is a lot better.
Just have to be lucky what will arrive.
