So I use to have MH in my tank a decade ago, and also had T5s, decided to take the plunge and get LEDs when I got back into the hobby. Fast forward , and was scratching my head at my frog skin acro….kept messing with the light intensity because the light just looks a tad dim to me. Then it dawned on me that I bought a Par meter and it’s just sitting in the closet, it was the first thing I bought when purchasing my tank. Holly crap are these LEDs bright! Reading 400 par on the bottom of my tank, had to lower the intensity to just 46% to get to the 300 par on top and 150ish on the bottom. So lesson learned on LEDs and glad I bought a meter, a must have now for me, especially with these new LEDs and strongly suggest a light diffuser.
