The new QB 648 Diablo from Horticulture Lighting Group

So I pulled the trigger on 4x of these Diablo QB648's. This will be my first venture into building a light, but I do have quite a bit of experience with electronics and electrical systems. However, I want to make sure I am not going to either damage my new boards, or worse, burn down my grow room.. so hopefully you all can give some quick advice?

Does this power supply EUD-600S12ADT Inventronics 600W 12500 mA Constant-Current LED Driver work for safely powering the 4 boards I purchased? *NOTE: I have already paid for it.. but I suppose I could simply return it unopened and purchase the right one. I want 600w total, with dimming, and most important.. safe.

Does 18g solid core wire work for the connections? If not, what is better? I am also assuming it would need to be 18/2?

I am thinking of a copper sheet, attached to a diamond plate metal sheet on top, for the heat sink/frame. Boards will get attached to the copper plate, which should help dissipate heat into the diamond plate 1/4" steel.. and the air gaps created by the diamond pattern should also help with heat.

But again, this is new to me.. and you folks seem to have some serious experts hanging around in here. Any help is very much appreciated!

Yeah that'll work. Maxed out you'll be giving each board right around 3.125amps or around ~170w each, depending on forward voltage of the boards. I'd think that heatsink should be plenty to cool these.

For wire, I'm no expert but the thicker the better imo. I'd go with no less than 14g solid core copper wire, maybe 12g.

Thank you very much for setting my mind at ease.. can I ask about the gauge and wire? Is the solid core 18/2 what I need?

yeah I forgot and then re-edited that info in ^^ I have 2 rspecs running on a 320H-54A and went with the 14g for that. Pushing similar volts and amps and that works fine. Wire might get ever so slighly warm at max but nothing I'd even think of worrying about.

PPF by nm or nm range. Any sphere or gonio can give it. Or can be calculated with a PPF output and SPD chart. Up to the users to know what that data does for their intended crop.

CRI and CCT have ever been pushed as horticulture metrics.

Vendors can decide who they want to market to. And present the data accordingly. Guess it all depends on who they are trying to capture, as a market.

If the data is presented in readily digestable format that is universal, then it gets a whole lot easier to compare competing products. I like the your mention of PPF by nm or nm range. Bar chart would be good. (Once saw an example, that had some info presented in pie chart form. Cant remember whos product.)

A potential buyer should not have to come to a forum like this one, search for The Maths Behind thread and learn how to use digitizing software. Useful skills to have for sure, but that is the vendors/testers job.

PLC's Photoboost strips have a chart like that.


Looks more like a doughnut or a bagel though. Lol

No dog in this race. Only providing the info.
I generally recommend 90 cri white diodes but not for the cri in itself, plants wont care about what things look like to our eyes, but i do like the extra red and far red. To me it just seems simpler to have the extra red baked into the white spectrum rather than having a few red diodes turn on for flower. Or-gros sbs seems to confirm this. If i had to build a diablo-like light id go for 2700k 90 cri white and then a wide violet/uv/480nm on a separate channel.

Me neither, but I love canines. I feel chip level cri is probably more important than board level.

You mean a fully transparent cadillac test approach like this?

These are recommended standards for testing.
I'm talking about a universal set of standards for presenting consumers with the data (from those tests) in a readily digestable format.
Loads of vendors are doing well by listing stats. Just a little more info on spectrum/PPF, in say, bar chart format would be good.

What important effects do various combinations of spectra have? Ratios?

In that article by Magagnini, Grassi, and Kotiranta they also displayed ratios of blue/green, and red/far red. If vendors are going to market horticultural lights, what relevant and rapidly digestable information should they be displaying on spectrum?

I like the way Kotiranta's paymasters (Valoya) present it.

i don‘t think we are and we will not for a long time be at a point where one can say, with confidence, if i change that wavelength to x, y will happen.

It appears that some manufacturers are in a race to supply product based on efficiency. Good stuff.
But there are other manufacturers who are focused in trying to narrow down, and highlight qualities, other than efficiency. I guess we shall see.

as long as fixtures don’t allow a wider adjustment over the whole spectrum this is useless. you only get a product that is good for one outcome, if any. just look at salad and how many different light recipes are there for. it all depends on what a grower wants to achieve, and what kind of plant he is using. in the end, you will have one specific recipe for your very own cultivar after a long try and error process. IF you are doing proper AB testing. if not, its just playing around for fun. look what bugbee et all are doing, that‘s the status quo. anything going deeper than that ist just anecdotal stoner knowledge without any factual base. and you want the fixture manufacturers to make any substantial claims about their product? laughable...

where are the big led manufacturers with their own grow chambers doing any experiments? exactly.

Cannabis is a pretty unique plant. 8 week flower cycle indoors leaves lot of room for exploring. Maybe these big led manufacturers do work with select big customers. When you see commercial growers utilising expensive lab tools, you know anything they might glean is commercially sensitive and will be kept under wraps.

Theres miles of difference between manufacturers. Reporting Kelvin and CRI is better than nothing, but can be misleading. Different products with the same K temp and CRI can have different spectral quality/ratios. Not everyone uses LM301B as a base white.

Hey @hybridway2 have you had time to peruse the QB 648+ datasheet yet?

Section 2 (characteristics) a) (basic information) rated lifetime is >50,000 hours
and under "Remark" "L70B50" is shown.
Click to expand...
Are you serious?
That's freaking awesome!!!!!
Thank you @Stephenj37826
Pretty sure you know i am NOT knocking your board. Its bad ass i bet.
Constructive Criticism comes from me no matter what company it is. I also point out the good things. Often in a seperate post to stay on topic & not ramble.
Only trying to help. If you want me to reduce such talk or keep it between us i will. Just lmk.
Big Ups for posting the L/70, B/50 rating. That takes a man to do.

So the Diablo Board is rated by Samsung as having a max input wattage of 129.4W. HLG states the HLG650R as being 610W putting each board at 152.5W. Clearly that will raise Tc and drag down lifetime performance effecting L70B50.
