The picture on the right looks like a Palythoa to me.
As fort384, technical reviews on the Marineland "Reef Capable" LEDs indicate they really aren't (reef capable). I did see a tank with TWO of those units on it in That Fish Place that looked to be sustaining / growing some LPS
That aside, I have to think they are brighter than an old 15W T8 bulb. Zoas are a little finnicky IME when it comes to almost any change. You could try screening the new light (place a screen under the light to dim it). If they were established, I'd bet they open back up in a couple of days. If they are new, you might try relocating them to an area with more or less flow.
