Hello! I just recently upgraded my 33g to a 65g. The 33g had a single XR15 over it, this 65g has a single XR30 (minimal rockscape so the spread covers the rock area perfect). I basically copied over the exact same schedule, intensity and everything, but I noticed the XR30 seemed A LOT brighter. My question is... do the xr30s output more par than xr15s with the SAME schedule and SAME intensity? I assumed they didn't but this has me second guessing, so I'll probably get a par meter from my LFS to verify, but I turned the intensity from 70% down to 50% for now JUST INCASE. If anyone has some insight I'd greatly appreciate it. Thank you
