I purchased a 4000 quantum board on ebay..
It is almost the same specs as spider farmer and uses the same samsung diodes and meanwell driver for a bit less money and a US seller. So far it has been a great addition to my grow room. View attachment 15174 View attachment 15175 I'm also augmenting with a couple of extra ABI red 660-670mn spectrum clip ons lights during flower. There are so many great options out there. Good luck on your search.
Almost 70 now. But if hot that's not overly good on the leds lowers life. Put a fan on top blowing at it to help cool down. Poor heat sink design.I came across this for $20 so I decided to try it out: (not sure if code still works but message me if interested)
Looks good in my 2x2, only thing is the top of it gets really hot like an incandescent light. Is this normal for grow lights?
I'm currently using led shop lights and they are very cool to touch (minus a 3" section)

Great lights. I awaiting for delivery today for 2 more and exhaust fan.Cola, I've done some comparing and I'm taking your advice. I'm bidding on a Viperspectra P600 on E-bay right now. If I don't win it I'm gonna buy one anyway. Will use it in my new 2x2 veg tent. Sounds like the perfect fit, a great light and price like you said.
