Thinking of changing my MH lights...I need some suggestions.

[Rippin]

Hi all,

I currently have the Coralife Aqualight MH 150w 36" over my 50g tank. The tank is only 18" high so I think light penetration is good for what I'm keeping (softies and LPS). But because this fixture only has one MH bulb in the center, the sides are lacking good light.

I'm considering a new lighting setup but I do like the Coralife configuration - all-in-one MH, Actinic and Moonlight LEDS with separate switches and power cords, AND it looks good and comes with stand legs.
I'd love to keep this configuration but have two 150w MH bulbs.
Are there pre-configured canopies out there like what I just described?

Will two 150W MH bulbs be too much light/too hot for my shallow 50g tank?

Suggestions appreciated!

Help me Obi-Wan-Kenobe, you're my only hope...
