Hi all Bros

Have been thinking of changing to Metal Halide lighting for my 5x2x2 tank. After some read up I believe 2 x 150W should be sufficient. Also notice that most of the MH lighting comes in pendant form. Thus making installation difficult as it is ceiling mounted.

1) Has anyone seen those tankover type? What is the pros/cons?
2) Any recommendation of a reliable MH? Which LFS carries them?

Million Thanks in advance
