However the 942 spec bulbs have a nice little spike in the UV range which is 'supposed' to stimulate resin production.
A lot of people seem to be really enjoying the agro spec bulbs though(3100k), I think it's going to be the new benchmark moving forward.

Yeah, those are much better than even mid-range LED in my mind. 450~ for 315w that can do better than 1gpw is hard to beat by any company

So when will be seing CMH with a deep red pontoon attached?

I almost bought some 315's but LEDs especially the COBs are a better fit for my grow area,growing one large plant scroged in 3x3 tents.
I would also like to see a 4000k CMH supplemented with 630 and 660 nm LED but I really think it's hard to beat the simplicity and quality you get from high end COBs.

Eh the sunsystem and cycloptics systems are super nice and probably the best bang for the buck.
Depends on how hb and plc set their prices at.

Wow, the arrogance of some people due to their own ignorance or dillusions of intelligence. How can you slam such an entrepreneurial venture? And how well is your light company doing, that's right, you don't have one. Hey, keep up the good work and good luck HB.

Hateraid flows freely I see. It's about choices folks. Just because something is good for you does not make it good for all. And quit with the keyboard cowboy crap.

We're hoping to see more manufacturers (and DIYers) reporting their fixture spectrum and output in PPFD (µmol*m-2*s-1). There's a push to establish a horticultural lighting label.
I couldn't find the spectral response of the Sun System PAR quantum sensor or the UPRtek spectrometer. Some sensors don't pick up the full PAR accurately and have to compensate. I typically see a swing of 5-20% in PPFD when I use different quantum sensors.
Also, the fact that the red peaks are lopped off raised a flag for me. They might not have calibrated the UPRtek spectrometer for each light. Those should be smooth peaks in the red.

So, what do ya want to see, a true side by side, cob vs hps in similar wattages? Well stay tuned, getting it laid out to fire up real soon...till then, keep smoking!

And I will be using Phantom Ballast's and Hortilux Super Hps bulbs, so no skimping on the hps side.

I will help to squash one way or another the hps vs led debate. At least one side of it. Have posted a heads up and will be looking forward to a good Ole fashioned shoot out!

You know what the great thing about science is? It's true whether you believe it or not.

I chose other. Blurple. Specifically older Mars 3 watters. 90% of the RIU crowd is just plain too stupid to be giving advice. So I went against the popular opinion on RIU.
Peace and love.

That's fine. Those are junk lights, and you've got reviews and opinions of people who have bought those in the past. I find it laughable that you'd call 90% of the RIU crowd stupid, as they've probably forgotten more than you'll ever know about this subject. 3W LEDs are a joke. Sorry if you don't grasp how full spectrum lighting is way more efficient than monochromatic diodes. But just because you can't or refuse to grasp the science, doesn't make them wrong or stupid. Quite the opposite, actually. I wish you the best of luck and hope that you're well off enough to be able to afford shooting yourself in the foot like that.
But what you just said there, is akin to walking into NASA and telling them they know nothing about rockets, and then investing in all of their old tech that is essentially obsolete. Have fun, guy.
