I recently acquired a mature aquarium with a Maxima clam, large bta and several soft corals as well as a green slimer. The 150w metal halide bulb is a few years old and want to replace it.
This is probably a dumb question, but what is the difference between a $14 14k bulb like this http://www.amazon.com/CBConcept%C2%AE-Double-150Watt-14000K-Aquarium/dp/B0050JC88S/ref=cm_cr_pr_sims_t
and the $59 14k bulbs sold through sellers like Drs Foster and Smith?
