Bulb recommendations? 14 bulb t5 Constellation fixture

[Oxymoron]

Hi There, I am looking for bulb ideas for a 14 bulb, 72" Constellation t5 fixture.

Features:

Unique aluminum fixture design allows the fixture to be placed directly on top of tank without dramatically heating the water or fixture.

48" fixture can hold up to 7 54W T5 HO lamps and 72" fixture can hold up to 14 39W T5 HO lamps

48" long, 14" wide, and 3" high / 72" long, 14" wide, and 3" high.

All fixtures come with 98% reflectivity Miro Silver full-length individual reflectors for maximum light propagation.

Quiet dual ball bearing fans on top of fixture help displace heat away from the tank.

All aluminum construction for a light weight and ridged design.

All fixtures are powder coated for extended fixture life.

Three switches on fixture for dusk / dawn lighting or for reduced lighting applications. One switch for 3 rows, another for 2 rows, and the last switch for 2 rows. Also, separate power cords for each of the switches.

Splash shield keeps the bulbs safe while also helping to keep the heat away from the tank.

On a side note I'd like to mention that I like more of a blue spectrum rather then the typical 10 k halide bulb. Also I really loved the fiji purples, so I would like to incorporate them as much as possible.

Any help would be muchly appreciated.

Thanks all.
