Glad you're tagging along.
I may stay current with whatever new LEDs come out but I would reconsider your premise that new technology will make existing LEDs obsolete.
That concept holds with computer systems because they have to be fully integrated and new software wont be compatible with old systems, or will require more memory or processing speed than old systems can provide etc. Here we're just talking about lights. There's nothing it necessarily has to integrate with so provided that it meets a threshold that it provides enough light today for the tank, anything that comes out in the future is just potentially a more efficient, more powerful, or more feature laden light. It doesn't make anything obsolete b/c the old version still turns on, still provides light for your system. For instance I have the old version of the AI LEDs as well That's still a good light (that I should find a use for since I only have 1 tank set up at the moment).
Now i do have my AIs hooked up to my Profilux controller, but they work together (and it's not necessary that I use both together --though i would always try to do that).
anyways -- people have gotten very used to saying "the technology is improving" -- and it is! but that doesnt mean that the right system cant do the job already.
The cool thing about LEDs is that they are so easy to control digitally... which makes for lots of possibilities. Many of those I already take advantage of with the Profilux controller, but who knows maybe someone will come out with something in the future that is a feature i just have to have! Outside of that, I think the only thing I would get a new light for is a different color spectrum with more purple. AI chose 470 nm for their blue. I would like it if i could get something closer to 420 nm.
If i continue to see good results though, I would not be in any rush to change my lights if new ones come out. the only thing i'm wondering now that the nem seems to do well w/ LEDs is is there a way to get my Pearlberry to color up -- which may be more related to the tank owner's inexperience with SPS, considering it's my first, but who knows!
