Define success?Most likely true but their money source is coral and if the lights did not support their money source adequately then it wouldnt matter if they were free or not.
I'm not a big fan of my XR15 lights either. I give them a B grade overall but it is obvious that big time coral vendors have success with radion lights.
Color pop to sell coral? Or provide the best for long term coral growth and health?
I’m not saying they can’t do the job but the vendors give the big name the shops to use as advertising. They are then reviewed by the big name website owned by the company that owns the light company
New people see all this and think it’s what they need. Surprise happens to be the most expensive. Surprise 2. They are average
