When I had my issue they sent me the wrong driver too. Then they ended up not having any more in stock and sent me a while new light. Both came in a couple of days thoughI finally got a new driver from Mars Hydro. It came from China and took three weeks of emails to get it done. Guess what ? The new driver was dead on arrival. The old driver is a MOSO, the new driver is Mars Hydro branded. It is just dead. I will see what Mars wants to do now. Hopefully, it will not be another three week ordeal
