Here we go again. Do a General Search of the website under Odyssea or Aquatraders and you'll get additional info. My personal observations is that no one seems to like their halide systems for fear that they will catch fire. I own some of their 24" dual T5 lights that light up my 180 gallon and 265 gallon FW Discus tanks, and I like them. These are "look at the fish lights" only, nothing more, but they are aluminum cased with separate, removable, aluminum encased electric ballasts.
