Don't get me wrong, the Coralife or Aquatraders lights do not "need" to be upgraded. They are fine for softies and LPS and even some SPS. My corals grew well under these lights for 6 or 7 months. My tank is now mostly SPS so thats why I did the upgrades and they have definitely benefitted from the brighter light. For example my pink birdsnest went from a peachy color to bright pink with purple polyps with the new lights. The growth was always there but not the color. All I'm saying is there is higher quality fixtures available, and depending on what corals you end up keeping, you might find yourself needing something better.
