LED For SPS?

[dmStewy]

I am looking at upgrading the lights on my 90 sps tank to LED. Currently this tank is running 2x250 MH and 4x54 watt actinic T5s. I am trying to gage how many watts of LEDs I will need to accommodate this tank and make the transition smooth. Also any thoughts on the growth rates and coloration of sps under LEDs would be appreciated.
Thanks

What's the dimension of your tank? You'll probably just need 2x 160w LED like my tank.

About growth rates and coloration, read here:

You could probably do a 90 with 48 LEDs, 72 if you want to go nuts. So 150-220w assuming 3w LEDs.

i went with AI's. I didnt want to blow anything up due to my faulty wiring on my part. I like the AI's because they are very clean and easily upgradable once new technology is invented
