There wasn't a consensus on the growth of LED vs. T5. Jake said he's had successful SPS growth in an LED tank. From my experience, I have T5 and a reefbrite 24" strip (blue). The PAR of an ATI blue + is around 2-3 times more than the reefbrite. With that being said, it's not an apples-apples comparison as the LED has a different look & spectrum than blue +. An actinic T5 and reefbrite LED are comparable. The LED blues are royal and regular blue, each is a little different and each LED fixture has different combos, i.e. white & blue mix. some have different colors. The meat of the talk can't be summarized as so much was covered. My takeaway is what it boils down to is LED has a lot of options and types of fixtures, you can't easily lump all LEDs together and categorize them. Jake felt strongly that the future of reef lighting was LEDs and MH & T5 are on the path to obsolescence. Hope we're not derailing the thread too much. I'm looking forward to getting Reefbrites in a BAR LFS.
