I was browsing the interwebs today pondering light spectrums and bulb combinations (as one does), and I stumbled across the existence of a T5 bulb made by Korallen-Zucht that I hadn't seen before. It was called Great Barrier Turquoise. It has a very interesting spectrum to me, because it's peak in the cyan spectrum is missing in the vast majority of bulbs and fixtures that I've looked at.
I'm currently running Kessil a360x in a T5 hybrid fixture with some blue plus and actinic T5 bulbs. After watching some of the recent BRS lighting videos where Ryan brought up the spectrum usage of peridinin being in the cyan end of the blue spectrum, I've been messing with my lights trying to add more coverage to that specific spectrum range. While I was doing that, it made me realize how much closer my tank looked to underwater ocean photography, which is often drowning in cyan instead of the dark 'windex blue' of common reef lighting setups.
Unfortunately, the best that I could figure out to fill this bit of spectrum was to just crank up the green supplemental channel on my Kessils and hit the cyan where the main blue channel and the green channel overlap.
Which brings me back to this Great Barrier Turquoise bulb. It's spectrum seems absolutely perfect for filling in the cyan color band. Since my Kessils cover most of the same spectrum as my Blue Plus bulbs, I would LOVE to experiment with swapping the Blue Pluses for some of these in my T5 setup. Is there any chance you guys might decide to carry them in the near future?
It seems to me a video comparing the output of these bulbs to the "peridinin shoulder" that Ryan referenced multiple times would make for a great marketing opportunity to sell a bunch of these.
I'm attaching the spectrum chart for the bulbs that I'm referring to to save the curious a few clicks hunting it down.
