I ordered 2 of these “B” grade Growcrafts. As expected, they are flawless. You have to really knit-pick to find the scuff. Nice light output paired with 4 chilled logic pucks. Worth every $.

Would it be more cost effective to upgrade my current light or just buy another? My light if upgraded would need two new bars to make it wider to make room for more lighting boards. Then there’s the cost of the light boards and then the driver.I’m running an X3-500 whats after that?

Amazing quality, no idea where my defect is as my bars looks spotless.

When it showed up I had a hard time finding and dings or marks that would make this “ b” grade. When I did find the mark it was small and I would have easily assumed it happened during shipping.
