Before you even answer...what do you want? LEDs or halides?
What oral do you want?
You can have a great SPS tank with a 6x54 ATI Sunpower /TEK & ATI bulbs.
You can have a great SPS tank with a 2x250w halide, + 2 VHO, or 2/4 T5HO supplement is even better.
You can do a cheap reefbreeders/evergrow LED setup or whatever LED is similar,or pay a lot more for a better looking fixture with more bells & whistles etc.
I for one like halides...with or without VHO Actinics or T5HO. Although together I think it is best- the best SPS growth, brightest & best shimmer together (shimmer is better with higher wattage halides or without fluorescent supplement)
I also have an ATI Sunpower & know it has plenty of color options & has as more than enough power to grow big SPS tanks. Look and see, it also doesnt make the annoying shimmer lines on your ceiling & walls like other lighting.
There are Led tanks that are SPS dominate out there but I really believe it depends on the user & LED system in use.
Some people push their new lights so hard but don't have SPS dominate tanks & don't dose at all and say its awesome..dig deeper and find out if its the right lighting system for you, the only reason I even say this is because many LED fixtures & users may not be like you...a lot of led users struggle with it & go back to halide & T5HO. Research is key!
