Your friends will turn green with envy, that's for sure!

I already spent some time on the live configurator of led tech, I Went on a base of 10% deep red 660 nm
and 2% maximum of far red 730nm of the total power.
After the tests I think ~ 7 % 660 nm, the far red 730 nm will be limited to 2% of the maximum power to avoid trouble.
So 4 Zeus XT boards 3500k
~ 2a = 308w
~3a = 473w
gives us 20w / 33w of 660 nm oslon ssl150 hyper-red at 350ma (6%~7% according to the bin)
and 6w / 9w far red 730 nm ssl 120 at 350 ma I don’t want run the board 3amp but I can always add extra boards or strips to save leds in time and get more efficiency, with 2 extra Zeus boards 2a I am ~ 462w

here are some pictures of the material.

2020 profile 10x1000mm + 2x255mm

the frame is currently 1040 x1000mm, I think to enlarge to 1120x1000mm to have the possibility to add strips


Here are the two drivers, I thought to make two small frames and I changed my mind for a single larger, here I am with an elg-240-c2100a so I do not need it...
Led tech recommends a hlg480h-42a with four parallel boards max( I have to ask them why four boards max).My first choice was wiring four boards in series with a CC driver ... which are, I find much easier to use and I'm always scared by these stories of thermal bottling. I still followed the manufacturer's recommendations.
(led tech answered, no problem for 6 boards at 1.9a, I did not see why not 6 or not 10 ^ ^ but I prefer to be sure)

boards Zeus XT 3500k. the blue ones are the first versions

I still have to add UV and red / far red. with 4 boards rated current 2a (77w) I have 860μmol / s, I do not use CO2, I target ~ 1200μmol / s for about 833 PPFD in 4x4 Space (~ 4 boards 2.8a) .I'm planning to add some strips / boards to preserve the leds.
Boards take a lot of space and are expensive..I think about the construction cost between extra boards Vs strip.
If I use the strips (Q series) I have to enlarge the frame, what add about thirty euros to the construction cost
(the frame will be the right size to accommodate the strips, I'll have to think of it from the beginning ^^).
there is also the additional driver costs that can be added...

I have to keep in mind that I need about 2x10cm for UV.

I will surely have saved a few(lot of xD) euros by thinking my fram with leds strips bought from digikey ^^. I thought there was a customs fee, shipping costs ^^. what is done is done ^^

Strips in CRI90 does not exsist, at least not with LM301b or 561c. Only Bridgelux has the Vesta series in CRI90, which is a two spectrum doulbe row strip. One side is 2700°k(129lm/w) and the other side is 5000°k(135lm/w). Each side is driven seperately on an own driver which allows to mix the spectrums. Unfortunately Bridgelux used their smd2835 gen.1 diodes and for this reason they only reach EBgen1 efficiency.

hello,
thank you it is very interesting.
I am from Europe and they are high shipping costs. Customs fees and additional taxes can still push up the bill.
Can you confirm me that they are strips 3000k 90Cri 190lm / w?

Nope, the description is too superficial and leads to wrong assumptions!
Cree J-series 3000°k/CRI90 is ~143lm/w at 65mA, according to the datasheet you get 24-26lm per diode and typ. forward voltage is 2,8v.(0,182w)
Only 3000°K/CRI70 is 190lm/w, CRI80 ~176lm/w.
The strips have 112 diodes in 16s7p, at 0,49mA each diode gets ~70mA and the strips are probably tested at 25°C.
IMO, same range like Bridgelux Vesta series, maybe just above but not much...
But I don't know which binnings are used. This is based on typ. numbers.. maybe there are better bins available(C5 for CRI90, D3 for CRI80, ...) I don't know..

Would be nice if you mention the used binnings(voltage and flux) in the description.
I would like to see them with LM301b or 561c in CRI90, 160-170lm/w...but that remains probably a dream ..!

Can one even get them in CRI90, Mark?

Because a HLG-480 has up to 550w and each board max out at 150w or just above that. And you don't need to worry about thermal runaways. The maximum voltage of the driver(45V)prevents them from drawing too much current.
Also if you drive LED's directly with Meanwell CV/CC drivers and stay in the constant current range(21-42v) they are driven in CC mode. Only above 42v or when you use secondary LDD drivers the run in constant voltage mode.
860μMol/s/m² is with HLG-480 fully ramped up? Sounds a bit low for 550w.. should be ~1200.

With an ELG-240H-C2100B you need 3 parallel strings to drive Q-strips at 700mA. Nom. they are driven at 450mA and max. current is 900mA per strip(180mA per diode). You have 119v to play with, so either 2pcs 4ft. strips or 5pcs 2footers and this 3 times in parallel. Way too much for your frame if you still plan to use deep and far-red.
H-inFlux series also use LM301b but L09 is for instance a 2ft. double row strip with 128 diodes. 2S2P with this strips would work. 2 in series two times in parallel would be ~90v @ 2,1Amps ~190-200w. 1050mA is just above nom. current(1000) you would get ~175lm/w at 47-50w per strip.
10x L06 strips (5s2p) instead of 4 L09 (2s2p) is also interesting and more efficient.(less current per diode) and with 5 strips in series you would use 112v, that's at least 235w. But I don't think there in enough space.
It depends on how many strips you can attach to the frame. There is not much space left but 4pcs 2ft. L09 should work. They come with aluminum PCB and reach 55°C at 1A. You just need to glue them on an aluminum sheet for more rigidity and screw them on the frame. Double sided thermal tape is cheap, the blueish ones from am4zon/e3ay work very well. But you can also screw them without a TIM* if you want; strips and boards don't need that. Just make sure that they have good contact to the surface.

(live configurator system) 860μMol / s / m² with HLG-480h / 42a, four boards, 2a per boards ~ 308w,
with 3a per board I am ~ 1300μMol / s / m². Max board current is 3.5a.
I have about 40 / 44cm of free space between the boards.(16/20cm) are for Uv.
the width of the Q series is 1.8 cm, I will look for the H-influx series, it should pass ^^.
the goal is to preserve leds, I can already get the desired power as it is. I intend to use these lights for many years, I need flexibility. I am still on red / far thinking,
I do not like the modules,I think there is not enough space between leds,
I thought about 20/25 led 660nm, 6/8 led 730nm .
Of course if lm301b / 561c are available in 90cri I'll go with lol.
The price boards is not excessive compared to the Q series with material.
I am not looking for the Max ppfd but the most pleasant light for plants, efficiency is for the bill^^.
(I keep in mind the possibility adding vero Cri90)

I thought run boards as low as possible to preserve the led,
but I would not add extra light if you think it's useless.
If I can fully run the 4 boards on the 480H-42a it is enough for me, especially the boards do not heat that much.
58.8C ~ 3.5a/140w at an ambient temperature of 29C
and stress test is
65.8C ~ 4a/160w at an ambient temperature of 29C).

This will allow me to concentrate on improving the spectrum with Uv and red / ir.:wall: :joint:

Yes thats a fair point, working on a new web site so the data on the current web site is kinda legacy, the new site will be much more detailed. The energy requirement to convert higher red based phosphors is higher than blue based phosphors so will never see eff numbers like the the 70 and 80 CRI parts(never meaning today) We stock the 2700k 90 CRI in C3 bin and the 3000k in 90 CRI in C4 bins, our 80 CRI are all D3 bins, for premium 80 CRI our Nichia strips are P12 flux bins in V2, we expect this month delivery of V3 P12 bins, 5-8% improvement over V2, these are 36-42 lumens and sit right on the same level as LM301B, these will be 80 CRI

We can assist with the custom fee/taxes, 90 CRI are not 190LPW, lower due to the higher Red content, LPW is typically 145LPW

I should note we dont stock them but the new Nichia V3 in 3000k 90 CRI are in fact 165LPW?

Tse, seems I'll have to bite into the bullet and pay shipping / custom fees this year. Wish sometimes I lived in "down under" ... Gold, Opals, Nichia V3... Sounds like a paradise!
Maybe I give myself some for xmas, lol!

Yeah, the HLG-480 with 4 boards is more than adequate for a 4x 4'. It's not needed to drive them lower to increase it life time they last already 50.000h. You could glue a few alu U-channels on the boards backside to increase cooling surface. Every 10°C less case temps you can expect ~2-2,5% better efficiency. That's a lot and a few higher fins(30-40mm) on the backside would even lower the temperature by more than 10°C, after all, you would treble the cooling surface this way.

Hi Random, we have ways to avoid those nasty custom surprises, so I should embed opals in the skins, wow the colours under lights would make the skin a real jewel. Would love to have your business

Hehe! Solskins are already jewels and with the choice of possible diodes they are even unique. I've been keen on solstrips with Nichia's and XQE's since the first day you posted a few pics in the solskin thread. But then I had already gotten my 20 F-strips and my new light was almost finished.
This year I have to have some because with v3's they are just more desirable :hump:
and if we find a way to lower the custom fees that would be great.

Construction evolution :


Fram 104x100cm
construction cost ~ 70 euro




41 cm free space between boards
Boards are 10cm from walls.


I just received the 2x39w for UV
the drivers will be integrated to the frame

I will fix lights and drivers when my space will be free.
I still have a few days before the Goji ends. the elg240 will serve for the veg / pm space. I do not know yet how I'm going to add reds^^ (Cree90 - 660 / 730nm - Cri70 2k ...), I think quietly ^^

I would see some solskin on lol
