How do you know if you are using too much light?

Typically they will start to bleach and turn white
 
I have radions that ramp up and down throughout the day. If I recall correctly the highest reading during the day is in the 40,000 range.
 
Ok well that's what I have in a maze brain coral. Maybe I need to move that guy a little.
Posting a pic could help us know for sure but yea, if its starting to bleach it is probably getting too much light.
