There are a couple of things that can happen depending on the coral species. In the case of photosynthetic SPS varieties, you might see less polyp extension which may or may not affect the corals speed of growth. I have some Acros that I hardly ever see the polyps and it grows really fast anyways.

The worst thing is bleaching, which some hard corals can recover from, but it generally kills them. So it's safer to start out with the LEDs either dimmed if they have a PCM driver, or shade the corals with something at first, then gradually expose them to the stronger light.

Mushrooms will extend a bit smaller at first as they realize they don't have to hang it all out to get enough light density for their algae. Some soft corals like Xenia will extend shorter, again as a result of not having to reach for the light.

My LPS corals seem to not care one way or the other.

Great thank you!

Okay sweet thank you. Do you like the lights? How does it look with both on? And are they dimmable?

How far from your tank do you have them hanging? Mine came in today and I hung them quickly before work. It's about 14 in from the tank for now. It's a 20 gallon (not sure how deep but is 24" in length and not a 20 long if that helps)

That should work. Mine are 7" in a 180g (24" deep) and I still bleach stuff. Clams are on sand bed and a sps still growing.

Yeah, depends a lot on the depth of the tank and coral placement. I will vouch on them being super strong though. In a 55 gallon (19" deep) and 11" above the surface I still need a layer of window screen over the lights and my softies and LPS on the bottom to avoid bleaching.

I'm starting to have really good coral growth though. I think the corals just needed a long period of time to adjust to the light.

Mine took a long time to adjust, then took off.
