About 4 months I'd say, then setup a frag tank with a led light and considering doing T5 or MH over that!brando how long did you have the LEDs hooked up for before you witched back
The thing about the leds even with the ecotech, my reds were brown, all my gorgeous acans under t5 turned brown or orange. LPS bleached, could never tune it to match teh colors of my old TEK fixture and the shimmer hurt my eyes.
my cousin has been running the AI light for around 8 months now and his tank is okay, but again his reds are orange, his acans turned brown/orange and his sps some bleached while others love the light and are growing great.
I think that we need a lot more research/time done to build a good fixture. Think about how many fixtures popped up in the past 2 years alone... I've been in the hobby for 3 years and when I started LEDS were never mentioned, then BOOM everywhere.
I think like everyone else said in another 2-3 years they will be great and useful, but still long way to go. Until then I'm sticking with my ATI fixture and a strip of blue leds to give that night moonlight effect at night! :grouphug:
