Wavelength of that Photo Red looks good. Always wanted a HDS Hyper Red but it was out of reach. This might fill the gap
That wavelength is really interesting--I had not noticed that until you pointed it out.
That's a deep red! Not the normal orangey 620-630 color that passes for red in the LED world.
However, that means a significant reduction in perceived brightness. This part of the wavelength is so far out on the edge of the visible curve that you have to put in a lot more milliwatts to get out the same number of lumens. I am actually pretty surprised that they can get 100 lumens out of it, the same number that they have been getting from their 620-630 red. If you look at the curve for weighting the various wavelengths when you move from radiant flux to luminous flux, you can see that there is a really steep drop-off right around this range. (I won't put in links, but just check the Wiki page on Luminous Flux).
I have played around with this a little bit with the 5mm LEDs used in Photon lights. Moving from the stock 620 to a 660 wavelength produced a huge drop off in apparent brightness, like I would say a factor of four or more holding current constant. How is Zebralight doing it?
Still, the reds in that region really are gorgeous. I hope they can pull it off, and I will buy one.
