I have not heard of any personal experiences with any of these exact fixtures but from the specs they all should be able to handle lighting a reef no problem. The quality of the leds I'm unsure of though along with what optics they use (may have missed it in the ads). With your tank being 3ft you'll need to raise the fixture a little higher since they are best for 2'x2' but that's not a bad thing as it could make it much easier to keep a mixture of light requirement corals in your tank. You could keep your softies on the edges with high light lps
in the middle directly under the fixture where your light will be most powerful.
