I did received my Ray 2 DS, for a 36" X 18" X 24" deep tank.
Ancient setup : Beamswork led fixture 10000K 2400 lumens (low light if alone).
With a Fluval Glo T5HO single (Life-Glo tube).
I was not satisfied with light, bacopa caroliniana was struggling, showing eviden signs of etiolation.
I did install the Ray 2 DS (8 hours a day) and removed the Fluval Glo for now. According to the graphics, at 24" deep, I should have 40-44 PARs at the bottom. For my eye, it is not showing that bright, but human eye is subjective. I will see how the plants react.
I hope being able to grow ludwigia repens or cabomba furcata (red plants).
About the Fluval Glo, I could use it again later and put a better tube. Life-Glo is not great for plants I think. I could put a Giesemann midday later, or an ATI tube.
The Finnex ramp is sleek, I could put 5 or 6 over my 18" wide tank, but one think i dislike is the flimsy plastic supports.
