UV Inhibiting lens

I need to know. How important is a UV inhibiting lens for coral? Will my Acropora suffer without one? I'm not worried about my family because the my canopy is enclosed except at the back; which is nearly against the wall.

The only bulbs that absolutely have to have one are the double ended halides ( HQI )

I run moguls fine without a protective lens
