We could probably go further and say nothng at $200 is going to be good enough

If your fish were going to read a bedtime book they would probably strain their eyes

The one below may not be the best for SPS but it will be a lot more light (8600 Lumen) then Marineland's 1800 lumen light fixture.
Also this one below has OEM timer that can turn blue LED on first then whites, and turn Blue LED off last for dusk dawn effect.

However some people say that just Blue/White LED combo maybe not enough for corals (especially SPS) as they need full spectrum light available to them. From 420 nm or less, almost UV spectrum all the way up to 14k or even 20k whites including 450nm blue, red, sometimes little bit of Green, Warm White and Cool White. New LED fixtures are coming on the market now with full color spectrum adjustable features but they are pretty penny for sure. Maybe that is why you see some AI sol's for sale on here.

Example below will be most likely good enough for simple corals even SPS, but you may not get good color pop as with old MH HQI/actinic light.

Really? Mine seem to be "surviving" with blue and white only..

I grew sps under marineland reef brights

After I cut the fixture apart and replaced all the emitters with 3w emitters haha

But by the time you do that you might as well skip buying a freshwater capable light and buy a real led fixture
