I have 3 Viparspectra over my 210, I would recommend Viparspectra over Phlison.
My experience was Phlison and marsaqua were pretty much identical except for the lenses.
Phlison that I tried, white channel was more yellow than Viparspectra. I just didn’t like the white channel color spectrum.
Alot of this, is just personal preference.
IMO… Viparspectra has a better light spectrum. I also prefer the digital readout on the Viparspectra.
Unless they have recently changed the design, phlison has dials to adjust.
Also, if this is your first led light fixture, your going to need a par meter to adjust them.
Adjusting to the eye, will just burn up corals.
These have a lot of punch, blue channel set @ 80% on my 210 (29” deep) was 130 par on sand bed, 300 middle and 800 on top.
I now have my blue channel set to 60% and white at 1%.
As I went up towards the top, par increased quickly.
Also get 120* lenses, I got mine from AliExpress. ~$10 per light, well worth the 10 bucks. Very much helps with light spread.
They come with 90* lenses, upgrade to 120*.
Easy to install.
