what happened to plasma lighting?

Sorry, did I check up, and I ended up being wrong on that. They seems to be about equivalent. Found an interesting article comparing LED and LEP effect on coral growth and coloration.

Coral growth under Light Emitting Diode and Light Emitting Plasma: a cross-family comparison

With the advent of new technology, aquarists are able to customize light spectra with great flexibility. However, our knowledge of how light spectrum affects aquarium life, including corals, is still limited. Here, we show the effects of two light spectra, emitted by Light Emitting Diode (LED)...

It would suggest that the main issue about this tech is the acquisition cost and the spectrum (having an awesome growth on corals with washed out colors is less appealing to hobbyist than having a good growth with colorful corals).

Their conclusion is that this tech is great for aquaculture.

I can't believe they did all this work and accidentally swapped the acropora sample, making it impossible to draw any conclusions about acropora. They seriously should have repeated the acro trial.

Well after a year now, I can confirm that it definatelly grows SPS and does it very well.
Acropora humilis 1st pic 22cm across 2nd pic 9 cm ish across. So thats massive growth. From january 23, 2023 to this date

... and no algae at all in the system. Well done!
I love A. humilis. Thanks for posting the picture!

Tahnks, Yeah the lightrack is new thats why its still white, but yes other than corraline algae there is not much.Of course algae will grow very well under this light, but I have tangs, snails that take care of it
