To answer the question, Yes they can bleach in high light. The Pigment given to non photosynthetic corals serves as a type of sun block. If exposed the coral can sustain life without getting hurt by the sun. However if the light source is too intense and the coral does not get the proper amount of shade that it requires then it will indeed bleach.
To be more exact the type of lighting that would be bad for them would be as an example 150W MH lighting on an aquapod or cube, exposed as you would photosyn corals. Far too intense for a non photo coral long term, it may take a while but in time it will indeed bleach.
