I have the first lights you posted with the 90 degree lenses and different colored LED's. I bought them on ebay and paid $253 shipped. They are nice lights, seem to be good quality, I have only had mine for about 3 weeks now. My LFS uses them over a few of their reef tanks along with a few employees there and they all said nothing but good things about these lights. I think they are a great deal considering you can put whatever type of coral, clam, whatever you want under them.

Oh BTW, they are really 120watts, not 165...even though some places advertise them as 165w.
