That is pretty much what I did. I took a razor knife and scored the black coating, then it peeled right off in one piece. I have a 23watt CF light mounted to the back with a 24VDC fan running on 6VDC. I will be switching to a 13 watt here soon. The 23watt is a 4000K and I want a 13watt 6500K. But there is decent growth with the 4000K. Oh by the way, I just filled it with Chaeto and some other type of macro I cant remember the name of. I'll be trimming it tonight since it is packed in there now.
