I like that spectrum, especially for tweaking white, but it doesnt seem all that effective. 50w per squarefoot and only 500-something ppfd? The 4000k version is a bit more effective but i would still expect more at those power levels.
If you like that type of redblue spectrum there are better ways of getting it: luminous horticulture range cobs are on mouser but a bit pricey. Cutter.com.au got something similar but a lot cheaper, also in a sorta cob form factor. And on Wish you can buy lights w the same spectrum for about 15$ 100w but driverless boards so probably even less efficient.
Id like to see this spectrum grow though...

Or how about the 95cri 100watt bridgelux cob thay can push 350watts max. What....

Check these out @Randomblame @Moflow @Rahz

They give full photometric datasheets snd everything. 10,000 lumen at rated voltage. 30v at 3.5a

Thats not a bridgelux COB. Maybe they use blue Blux diodes as the base in this COB's but thats not a Blux COB. Bridgelux has own CRI97 COBs like the Vero29 Decôr Series(100-140lm/w).
On the strips they seem to use Yuji's or Seoul's high CRI LED's, 90-100ml/w, based on purple diodes. The strip spectrum has a blue peak ~420nm. They could have used Nichia's Optisolis(CRI99, but up to 160lm/w) but they don't look like Optisolis. I don' like such wishi-washi.
Strips and boards are also 24v CV which means there is a current limiting resistor connected to each 7 LED's. Thats not the most efficient way to drive LED's. They are more for photographers, museums and galeries.
For plant lighting spectrum 'and' efficiency are key features.
1x 2' Red boards are far to big IMO. If you mix a 4k and a red board you would get pretty bad mixing effect and end up with a red and a white side and a small area in the center with the desired color mix. Red strips between 4k boards would make much more sense. 6 and 12" measurings are also pretty low.
The calculator tool is also useless for other LED's like their own. It would be more useful if you could choose different brand LED's, drive currents and such things. You would need 50 strips to get 40.000lm out of 420w net.; with 35$ per strip that's almost 2 fu....' grands!! If you plan to make a movie, yeah, pretty good! But for plant lighting there are much better siutable products. To me it looks like they just try to give their product a second foothold because the ultra high CRI market is not very big.

You crack me up sometimes, RB. LOLed at wishi-washi... I have looked at yuji, seoul etc and yes, not ideal... Optisolis ftw
Yes to all above and glad i never had to type that out on my phone.

Do you know if there are any Optisoli strips available retail? Seems like something I'd love to get my hands on

Yeah I'm not buying any. Jus came across them looking at other stuff. They have a horticultural section. With a flexible qb knockoff. That you can bend over and make a circle with. I was lookn at flexible strips to make a birdcage for partycup grow. That was how I found the web page. And I jus seen where it they said bridgelux top bin chips. And can be pushed to 350w. From a single cob.

The 99CRI strips are probably great for photography, or just making it seem like you're outside when you're inside, but even though I was an early adopter of 90CRI I don't consider CRI a useful metric for growing plants. :)

I like 3000K 90CRI cobs just fine for a full cycle/flowering spectrum and I know I can get it in the 55-60% efficiency range for a reasonable price. I would consider going straight monos if the price/performance is right. I think a 10% blue 90% 630-660nm lamp would probably be very low CRI.

Maybe 350w pulsed as a kind of camera flash light. But I don't believe you can run each 1w diode in this little 28x 28mm COB constantly with the full 350mA(10.5amps). It's still the cheapest COB base ever and many e3ay/alibaba scammers call the diodes Blux but none of them mentioned 350w maximum on a 100w COB.
Flexible boards are a nice gimmick and would allow new designs but heat sinking is more difficult. Also the resistors would cost efficiency. You can get flex stips without resistors from alibaba, all diodes connected in series. You only need to cut them into the desired length and choose a siutable driver. Simply calculate with 3v per diode.
You can also get them with LM561c or LM301b. Meizu, R2T or other fake QB suppliers should have them. @VegasWinner has used them and a few others too. You can also bent F- or EB strips slightly to create a bird cage. I've just added four 2ft. EB side lights to the little 150w veg area I'll use for the party cup comp.

280µmol ppf from 108W is not that bad, 2.59µmol/J https://www.waveformlighting.com/datasheets/CS_2020.pdf

Im sorry but then im calling bullshit on either the ppfd numbers or the ppf/w(more likely). It does not make sense that this efficiency gives such a poor ppfd. Id expect the double at least. Thats what we get from the Fotop boards /lm561c which are similar in size and efficiency. We get around 600 @12".

why not? it's quite a large board with wide spacing between the leds

The boards we work with, Fotop, are 1x3 foot. We push aprox 150w per board, or 50w per square foot of board. Efficiency should be similar as they lm561-Alibabas.
The ppfd of these boards is around 600 at 6 inches. We get that at about 12" with pur Fotop, while these boards drop to around 200 and change. Doesnt add up. You can also refer to @Moflow fotop growpanel thread for measurements but i think they are for 200w total, or 66w per squarefoot of panel.
Id be all over the redboost boards if i thought they were 2.59ppf/w. The best ive seen for this spectrum is luminous horticobs at around 2 @25C.

Well waveform is sending me one of their white 99cri 1' ×2' boards for free. To test. So we will see how they do. I emailed them and they said sure I'll send you one. Already got the tracking number. So why not it's free. If anything itll make a good veg light
