Lighting: T5 vs Metal Halide???

[e46er]

Im fairly new to salt but from my reading on here people swear by both
both bulbs seem to last a year or so and replacements generally run the same cost.
6-$30 T5
or 2 -$80 MH (in my case)
t5 have more control over color and variation


i went with MH as i got a good deal on the fixture and i just love the shimmer


also depends on what you want to keep a fish only tank lights are for viewing purposes only and sps dominated tank your gonna need a good t5 fixture with good bulbs and a bunch of them
depth is a big part of the equation as light penetration is much better with MH as far as my understanding goes
anyone feel free to correct me if im wrong
