I am really thinking on taking the plunge into LED's but haven't personally seen great growth on SPS from fellow reefers tanks around me that are using LED's. I know the Par rating, cooler running temps, and energy saving is all their but is the growth??? I'm have a SPS dominate display running MH lighting with great growth would love to see some before and after pics of SPS displays with LED's. I would need 4 AI fixtures to properly light my 120 Display and need a little reassurance before taking the $2000 plus plunge. Thanks all and can't wait to see some pic's.
