I've seen many corals do fine under PC lighting. For God's sake, if PC lights couldn't handle corals, why would anyone make or buy them? And there are certainly a lot of companies making them, and a lot of people buying them. As for T5s, they're really just glorified PCs, so I don't know why people think they're so much better.
