Honestly I dont understand why so many people are pushing the use of metal halide lighting. These lights consume a tremedous amount of energy, put off tons of heat and are flat out too strong for many LPS
and Soft Corals. With the advances in Compact Flo., VHO
, and T5 lighting I just dont see why hobbyists are still quick to opt for halides.
On the other hand Halides provide the shimmer effect many people love and are great for keeping light heavy SPS
corals. Although T5 and Compact Flo. lighting would allow you to keep a wide, wide variety of species. Clams and even some SPS
corals can be kept under this lighting. More important then the light type is the wattage and spectrum and with T5 wattage is less important because of the type of output.
For the price you are paying for that Halide fixture from Aqua Traders you could easily afford a nice top of line Current or Coral Life fixture that would perform likely better.
