So this week I switched to the wide angle 120˚ lenses on my Radions. After taking some PAR readings, I switched back to the standard 80˚ lenses as the PAR was so low on the wide angles, even at 100%. As I have 3 x XR15PRO's above my tank, the standard lenses do the trick and I get great coverage and now great PAR too!
Below are my readings/settings. Im running them at 70% right now, but you can see what sort of PAR range I have up to 100% intensity. Obviously there is some variation in the readings as you go further toward the back glass/front glass. But all these readings were taken within the 6" center of the tank (front to back). PAR readings on the Apogee MQ-200 actually read <2% low, according to the manual.
At 70% they are incredibly bright already! I really love the Radion's. Im getting good growth from my SPS and i've kept colouration on 95% of them, but still expect to see improvements in colour as my SPS settle in and light intensity/feedings increase.
