I looked into Sunritek pretty extensively and they seem like a good choice. But...
Just get a Meijiu. I don’t know if it’s the best but it’s by far the most consistent based on my research. More people on this board have ordered from Meijiu on alibaba than any of the the other vendors. The most common Alibaba issues are things like not getting the diodes you paid for, different drivers than what’s listed, shitty quality, stupidly delayed shipping, product doesn’t work out of the box, order is for the wrong product, etc. In over a year of research LED grow lights, alibaba in particular. I’ve never once seen a user here complain about any of the above. There have been a few times where an customer received a broken product on delivery and Meijiu immediately sent a replacement part and payed return shipping. In one situation, Meijiu just let the customer keep the broken light. He ordered a new driver and it fired right up. I’ve also seen posts where the driver failed a few months after purchase and Meijiu sent a replacement driver ASAP. Lastly, users here have independently tested their lights with a PAR meter and they were as good or better than the claimed testing done in house.
If I had to do it again, I’d likely order from them. The other vendor id consider is umol technologies. I’m currently using their supplemental bars and have a friend using their 8 bar light. Waiting on him to get them tested.
if you give me your budget and an idea of what your setup is like,, I’d be happy to give you some specific suggestions.
You really need to be running a sealed room environment to have it worth much.
