Yes, how much difference does the 400-450nm segment make? I can see the absence of the huge blue spike potentially leading to less circadian disturbance. Maybe someone who already has one of the lower-CRI high-intensity setups could try this out, exchange which one is operating in which room, and see if they have a preference for one or the other. If the gradual color shift wasn't important, the setup would be very simple to trial.
A couple notes:
1. In regards to dimming, I have seen (fairly well-regarded) third parties saying that the CCT/tint stays pretty stable for the Optisolis under current-regulated dimming (as opposed to PWM), but I don't think Nichia themselves make... (read more)
The most 'natural light' LEDs I know of seem to still be too new to be commercially available in ready-out-of-the-box modules, but with a little time to engineer the setup I think one could assemble these into a usable thing. Significantly more deep purple wavelengths and less 'cyan dip' than the alternatives. Here is a quick comparison of spectra at 5000K, vs one of the Yuji 95CRI ones: https://i.imgur.com/6TFtPbt.png
Of course, these are not smart bulbs, so there's an obstacle to automation again. I think solutions from the indoor agricultural field probably exist, but I haven't found them in a quick look. Hard for me to say if the difference here is worth the requisite fiddling, but if there's interest I will take a harder look at what it would require.
Having not used them yet, I can't personally attest to the light being higher quality, but the custom flashlight community is pretty discerning and they seem to be quite taken with them.
That's a pretty good thread, and also reveals that there is an existing single-component solution for the scheduled dimmer potentiometer, from the aquarium sphere, which I hadn't thought of at all. A hundred bucks is a bit more than I was hoping to see, since you still probably need one for each room, but at the very least it simplifies things for the early adopters.
I thought the strips seemed pretty attractive for people making their own setups, since they can passively cool and are already somewhat diffuse. I do think the intensity is plenty high enough (20,000lm in a 56x26cm board), but these Bridgelux COBs the fellow mentions are 10-15% as expensive... (read more)
