Thank you so much, that post should be stickied somewhere...

OK so we are looking at a considerable addon of power... The 300W unit you chose is quite convenient as that is about what I use over my 2x4 trays.
So we are looking at 300+25+50... = 25% additional power draw. Do you think the gains is worth more?

I do intend selling them though

Well I want to sell the light and FR/UV functions separate.
The design of my light makes it easy to clip on more stuff

Yeah, it's pretty easy to combine 2 or 4ft strips and UVB bulbs because of the same lengths. Add deep- and far-red to one or 2 additional c-channels/heat sinks and they can be added in the same way.
Easy and comfortable.. That's exactly what growers need.

Do you have the company already founded officially? ...with tax number and such? If not you could still say it for private usage and if you start to sell them officially sometime you can still import them commercially. As company you can also get better deals especially if you order them more often. These Prolight Opto diodes are pretty interesting because of their price/performance and you can may get them directly from Prolight.
Below are two datasheets...
The PKxx-xxxx-HSD diodes is their brightest deep-red diode currently and performance wise close to Cree's XP-E High Efficiency series from last year. There is maybe also something new or an even better bin when you contact them directly.

Nice. Any prices?

Looks like maybe their website data is off. The bottom crimson is defying physics lol but I think they may just have used a different bin for the top one or something. Has anyone tested these?

Yeah, the datasheets are a bit strange.
These two are different series. The HSD is newer and more efficient but I don't know if top bins are already available. Q and R bins are maked with(!) and you have to contact them to make sure you can order them. I've this datasheet since a around a half year so they probably yield enough top bins meanwhile.

They use probably the most efficient flux bin and a mid voltage bin...
I've seen PK2N-3LME-HSD deep-reds mounted on 10mm PCB's on e3ay for 1,80€ a piece. But can not say which binning it is. They mention 175-2,35v min./max., 100-700mA, 122-780mW, 0,673µmol/s - 4,30µmol/s and 3,85µmol/J - 2,61µmol/J efficiency. At 350mA that should be between 400 and 410mW typ. so its maybe Q bin. I've contacted the seller because of the binning but got no response till now.

Nice! If there is any diode one could use cutter seem to have them!
And it seems to be an even newer generation...
Q bin would be better like XPE2 or at least on par(450mW typ.) but below Cree's new XPG3(525mW). But still very good!
Do you know if he also sells them mounted on star PCB's?

Not sure if they do or not. I bought two of the strips. They seem to perform well, but I have nothing to compare to.

Yeah, I'll for sure make some testings and show how it works. For 25 bucks its really cheap.
Solarmeter is a well known brand for UVA, B and UVI measuring devices and they are pretty good but their meters cost at least ~200 bucks and a combo meter measuring both UVA and B cost even more.
@Randomblame
I can also figure out a lux to UVB factor for those having exact the same 12% Arcadia bulb and a lux meter.

Finally almost done and all is ordered but for blue 420-450nm ish on strips hopefully any suggestions?
Do I need them with solocure and Hlg UVA with tiny bit of blue I suppose?
There is the 5000k strips with 48 samsung diodes so that is alot of fringe blue I guess?
Also wondered if you knew drivers for the the strip HGL18 with the reds?
Max 2100mA 24+ VDC is what it says on strips.
Looking for single driver that will max out strrip on a 2 inch wide 1/8" think aluminium strip 36" long aluminum with eye bolt each end to make basically a single red light out of each.
I should be able to start soon I hope just waiting on shipping.

The study I read is easily 10-15 years old and I can't find it anymore. The question is answered easily enough; let the plants tell us!

It's certainly not worth quibbling over. I'm looking forward to the chance to play with it, myself.

My plant told me HLG's UVA strip does help with smell
hopefully THC increase corresponds.
It is quite odd indeed, everything else must be in order too though, VPD, Temp'

Nice!
What ya driving those with?
Will a Mean Well HLG240H-C2100B drive 6 in parallel?
Or perhaps a Mean Well GSC40B-1400 drive just one?
Make a nice supplement light on its own heatsink.
Add some UVB-A and white light 2700k and 5000k look out they will be killer I bet.

I've only got two and no heatsink, so I have them on a meanwell HLG 60-24A. I'd really like to add 6 more.

Having white light isn't really helpful on a research light for precisely regulating spectra and building precise light recipes. White light is a very practical and sensible for us as regular growers.

I disagree,
There are whites there if you look close enough
Seems both soft white and cool white are there they are just off.
Kinda like a huge light bright for plants, it will be extremely effective vers "full spectrum" white.

Yeah, UVB bulbs also have some light in the PAR range(blue) but only 1,5-2μMol/s. This below is an Agromax PureUV bulb(75/25% UVB/A) and Solacure bulbs should have a little more cuz they have more like ⅓ UVB and ⅔ UVA.
Agromax 18".jpg


The 430-450nm range is already covered by the white strips and I'm pretty sure the Solacure bulb has also a little blue like the Agromax bulbs even if you can't see it on the Solacure spectrum chart(SPD). They're only on for a few hours but I don't think you need extra diodes in this range.

It's not comfortable to power every single strip separately and also not very efficient because smaller drivers are usually less efficient.
An HLG-40H-24A or B has ~1,65A and is enough to run one strip at +40w. For 2 of them in parallel you could use an HLG-60 or 80H-24A or B(2,5 or 3,35A). Each strip would run with 1,25 or 1,67A and you would have ~60 respectively 80w out of 2 QB18's.
For 4 in parallel use an HLG-120 or 150H-24A or B(4x 30 or 37,5w) and for 6 of them use an HLG-185H-24A or B(~192-200w total, min. 32w per QB18.

To max out one strip you would need one HLG-60H-24A or B per strip. This driver has 2,5A and we actually need to set a voltage limit to not overpower them. But these Meanwell drivers come always with voltage poti set to 24v. This means you have to do nothing else as to check it with a multimeter. Is the voltage higher like 24v reduce it to exactly 24v. The voltage also limits the current flow and with voltage set too 24v the strip can only use 2,1A even if the driver has 2,5 or even more current. Even an HLG-240H-24 could be used to power one single strip. As long as the voltage limit is set to 24v the current flow is limited to 2,1A.

You can also use cheap 24v constant voltage no name drivers because the strips have a series/parallel circuit. But for dimming you would need a different dimmer. Those with 12/24v and up to 4A would be okay and because they use PWM tech you can use the cheap remote dimmers.

Thats a 50w no name driver, 24v/2,1A you can find on e3ay for 10-15€...

... and that's the according dimmer.(no dimmer wires on the driver, you have to connect them in series with the LED strip)

For plant researcher figuring out different spectra for different plant species and stages monochromatic light is more important. They can mix any type of white light they want by just mixing blue, green and red. If they have found the best veg and bloom spectrums working with all species they could create a white phosphor diode accordingly to create a veg and a bloom light. Osram has already done it with the horticulture Duris S5 and S10 series. To make it short, its a warmwhite CRI90+ and a coolwhite CRI70/80 spectrum.

Point is even if plants all use sunlight you can manipulate different species differently by creating a certain spectrum.
For leafy greens its for instance super effective to mix blue and deepred with yellow. Other taller plants(with intercanopy) rather like more green combined with blue and red(like tree's).
White diodes mix all these colors to a natural looking white light and compared to monochromatic diodes it's 3-5 times cheaper to just use white instead a combination of blue, green and red diodes.
Pretty sure such a Phytofy fixture costs at least 2 grand (or more) and has maybe only 200 or 400w in the best case.
It's a researcher light and for sure not the best solution to grow MJ.
Lets look at it from another POV..
We know a 3000°k spectrum is almost as efficient like a blue/deep-red combo with same efficiency. You can add lets say 50w deep- and far-red to 300w white to create an even better spectrum and a higher PAR output but you can also add 50w of white light and the final yield would not be much different.
The light with added deep red is probably a little more efficient and because of the far-red a little faster like 3000°k/CRI80 but in the end the difference would only be a few grams and if you use CRI90 white the run would be finished in the same time.
So in the end it only depends on how much are you willing to invest and which degree of optimization you want.

Great info. !
I need some zzzz's and go over it all again ..but.

I do have a HLG-240H-C2100B likely here by weekend, also
two Mean Well GSC40B-1400, one each for the strips that will be detachable if really needed (two bolted on frame)
one Mean Well HLG-320H-48B
half dozen rapid LED drivers
bunch of other stuff
four HGL18's @ 2100 mA 24 + VDC that at each have a combination of
6- red-far
8-deep red
4- far red diodes
so hence QB18
I can use plug in driver right into strip with the Mean Well GSC40B-1400.
Also have the HLG 36 UVA LED , same mA and VDC so I wondered can tht strip and the Red QB18 all go on the HLG-240H-C2100B ?
If I do that I have the option of three remote smaller drivers-mini light for side lighting in red's etc
as needed during a grow.


The 430-450nm range is already covered by the white strips and I'm pretty sure the Solacure bulb has also a little blue like the Agromax bulbs even if you can't see it on the Solacure spectrum chart(SPD).

I need to go over this again with fresh eyes.
It is exactly info I needed but you are way above my skill set but I am slowly getting better LOL
Good to know about blue I may still try a few strips while I am at it then I know for sure.
Will read stats om drivers so I get how you selected them,

I could have never tried to build this without your help(and others)!
Excuse my slow manner building it has be hard to get everything here where I live at a reasonable price.
I gave up keeping track of cost , just wanna get done , so far the results are frigging amazing.
If I have repeated myself I have not slept, not high...well yet anyways.
Thanks
