I am looking into getting some new lighting for my 180 gal brick. I currently have 3 Aqua Medic MH pendants (11" wide) (have had them for awhile) with 250W 20K bulbs. Any suggestions as to something reasonable out there to check into?

Space-wise: I have about 12" space to work with from canopy top to water level.

Never been too good with lighting - so some suggestions would help me to look into different options. Mucho thanks
