I wouldnt say that you need to move it out of the light. 175 is not normally too much light. I would simply try adjusting the flow first. I have several euphilias direclty under a DE250 and they do just fine. As a matter of fact, they seem to be doing even better under this lighting than under the indirect lighting that they were recieving from a SE 250.
Im not saying that at some point there cant be too much light. But if 175 is too much, then what can they take?
If you like its present location, just try adjusting the flow first and see what happens.
If it has never opened up, your lighting/flow conditions might not be the real problem anyways. It might have been in poor health when you got it, or it may not be happy with your water.
Hope that helps some,
