Metal Halide Bulb suggestions for 50 gallon

[hyndu]

I will be setting up a 50 gallon tank. It measures 36" x 18" x 19".

I have a 400 watt ballast that I will put on it and there will be a PFO parallel reflector behind the bulb.

I will probablly put one 3' actinic VHO on there later on.

My question is what MH bulb would you guys put on there?

I am considering putting a hamliton 14K; but I would like something with better PAR values.
