Hi,

Has anyone used a T5 overhead pendant light and how does it compare to a
metal halide system for similar? The metal halide system I am looking at
would be using 2 150w MH bulbs in separate units, the T5 unit I would
use would have 4 tubes in it.

I use interpet daylight plus T5s on my smaller planted tank at the
moment and really love the colour they give off, its a crisp white
colour which is brilliant. But I've seen large planted tank tropica sale
aquariums in aquatics shops, the one I'm thinking of uses 3 150w MH
bulbs and it looks incredible, I'm wondering if you can get that
shimmering effect from t5 lights? What do you guys think?

Thanks,

Neil

I've only ever seen that shimmer from metal halides. You need a point
source light to get it.
