One thing have to remember LED will never look as bright as MH or T5 to the human eye, but it still packs a punch as far as PAR and foot candles. I found this out the hard way when my Marineland LED fried my green birdsnest.

Yea you got me excited because I did not know about the S series, but after reading I found out it wasn't up to the P standards plus you have to buy a power supply ($86) so the excitement went away. I see your up in Lubbock but Louis at Elegant Reef can get "P" for you. The "S" is not out yet.
