We can all guess but the only way your going to know for sure is to check with a par meter. Do you have a local lfs or club that can loan you one for a day?
I use an Apogee but there are others like the seneye that are lower in cost.
That is the one major downfall of leds. You can tweak them so much but your not really getting anywhere without knowing what is actually happening in your tank.
Or you can do what I did and ditch the controllable led's. I could never leave them alone. Always making changes until I said ok it's time to reevaluate what my corals actually need verses me just playing with light settings endlessly ha. I ran metal halides back in the day so I decided to switch over to kessils/t5 because they are both set to the spectrum your corals need to thrive. Of course I have Orphek OR2 120's being delivered today. Hoping to replace the t5's and be done with bulb changes forever.
If you look at most online retailers setups you quickly realize that most have shallow tanks under led's. The reason is they can get much greater par that way. Then once you get home and place it in your tank you have probably cut their par in half. Imagine living off half the calories a day you currently take in. Now your body will adjust eventually just like the corals but you/it won't be too happy.
Bottom line is you need a par meter, ha!
