Bulb Advice Please!

Ok... I'm thinking about upgrading my lighting. Tank is 60 long x 24 high x 18 wide. I currently have an outer orbit fixture with 2 250w MH bulbs (electronic ballasts) , no name provided and 4 x HO strips (2 x 460nm blue slimpaq superbright blue and 2 x 420nm actinitc blue softer purple). Would there be any benefit in upgrading either the MH or HO bulbs? If so what brands/models would work well? Thanks in advance!

Stock fixtures usually come with lower end bulbs if you replaced both sets of bulbs I'm sure you would see a drastic difference for the better. I'm not a metal halide guy but all my mh buddies use either 20k radiums or 14k Phoenix!

Yeah that's pretty much what I figured. The lfs's around here have a huge selection of bulbs and I'm trying to figure out what bulbs/combo would work best... Anyone have reccomendations? Thanks1
