Ok, so you see now what I'm talking about how "brightness" means something different when discussing LEDs. It is "bright" but not the same way as CFLs because they leak a lot of light and the eyes see their light differently than LEDs. I was very skeptical initially when I saw them, though I too agree with your conclusion about the build quality. I have always used CFLs and over the years my eyes just became acclimatized to the way they shine light everywhere, all the time, direction nonspecific. With these, you get the PAR the same as you would with a CFL but without as much light leakage. I guess ultimately the proof is in your tank's results. I can't wait to see that CO2 bubbling away!!
BTW, IWANNAGOFAST - it's nice to see you around these days!!!
