I have also been looking at the HLG Scorpion Diablo here in the UK. They say it can be hung very close to the canopy. My concern is I have read on HLG website that when using their lights you need CO2 enrichment which I don't have. Do the CO2 bags work in a non sealed room(just intake and outtake fan)??

CO2 enrichment increases photosynthesis potential at all lighting levels, even low levels. If your scorpion is putting out more photons than your plant can handle based on your atmospheric CO2 concentration, then the answer is simple: dim the light down a bit. Easy peasy.

I'm looking for a new light too, found these three to be good: Mars Hydro FC 6500; HLG Scorpion Rspec; HLG Scorpion Diablo.

The Rspec is a 600 watt lamp and the Diablo is a 650 watt lamp - but I've read reviews saying the Diablo has hot spots and the Rspec is the better light. Does anyone know about this?

The FC 6500 is a 730 watt light and it gets great coverage.

Anyone have opinions or facts about these three?

If price isn't a factor the scorp diablo is the clearly superior light. I don't have one myself, too expensive for me.

Thanks PJ, I ordered my Scorpion Diablo yesterday.

It's going to get here just in time for my next bloom.

Congrats! It's a very efficient light, and a quality build, backed by a company with a great reputation for excellent customer service. I have some of their DIY fixtures, and have been nothing but pleased.

Don't waste your money, there have been plenty of growers here that have run tests, and they have shown that they don't work. One grower got more ppm just breathing in his room than what the bag was contributing.

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.
New grower. Got first Mephistos from Multiverse. I have a 4x3. Exhaust, filter, 6 inch fans. I have a total ac infinity setup. I have the Ionboard S24 200w light from ACI as well.
