Wow, great link, i've looked for those par ratings for a LONG time. I ran a 175 on my 55 as an LPS tank. I found it worked fine, i had a couple sps frags growing close to the light, everything else did well. There's some nice tanks out that use the cheapo's too, like the site said, you have to know that they're in the bottom 1/3 of par ratings. But, if you know that you can always throw another bublb across the top for some overlap, and if your tanks shallow shouldn't be much different imo.
For the record, i'm using xm 10K's now, and coral growth is FAR better... but new tank etc, so lots of variables thrown in.
