These arent new and the lum/w is not really representative of their ppf/w which os pretty much similar to standard gen3 90 cri strips, if anything a little less. This achieved by using narrow band red phosphor over a standard 80cri phosphor; the added red is in "spikes" rather than a solid "bump". Ive not seen this spectrum grow but i know the GLA boards use a similar type diode (same type of phosphor for added red) in order to boost red around 630nm which is a choloropeak. The reasoning why: 630nm diodes are fairly in efficient. The GLA board of course adds some 660 red aswell.
Heres some specs measured by led-tech.de:
Comes out as very similar to gen 3 tests that are here:https://www.rollitup.org/t/bridgelux-eb-strips-gen-3.980457/post-15502216

Id wouldnt rule them out, f ex if you where to do some red supp 660nm with your 90cri these may be a better fit. However a red supped 2700k 90cri may need to have some extra blue or uv on tap.

I had a look at the narrow band Bridgelux offerings lately. Their was something about them that really put me off of them for horticultural applications. I can't remember if it was the electrical specifications or if it was something with the emission, but something about them was a hard no for this application as far as I was concerned. Just my opinion. Rocket Soul definitely outranks me in this arena, I will concede.
