Well, it's good to find out what conditions it came from. I think that their light range is broad as long as they are acclimated. They can be down on the sand bed or on the rock stack. Safest is to start low in your tank and get them used to your lighting. Then if you want to mive up just do it gradually.
I have my chalice and echinos mid to sand bed.
