I don't think there's too much light at all.
I would just give them a few weeks to settle in, but from what I can see from your pics they don't look unhappy enough to move them down. Zoas can handle a wide range of par and thrive.
A good rule of thumb is to place any new coral on the sand bed and move it up a bit every few weeks to slowly acclimate it to your type of lighting. I lost a ton of corals when I first started from placing it too high or moving them too frequently.
