440 watts of VHO over your 55 would kick butt in my opinion.
Here's a couple of options you asked about.
If you don't want control over the actinics and daylight bulbs, meaning you turn it on and ALL four lamps light at once - this is a pretty inexpensive route.
NM reef has suggested this lighting - he may be able to answer questions.
LN Electronic 4 bulb VHO kit - 440 watts total
Includes ballasts, wiring harness and German end caps.
$139.95
(1) URI 46.5" 110watt Actinic 03 lamp $22.90 each
(1) URI 46.5" 110watt 50/50 lamp $25.90
(1) URI 46.5" 110watt Aquasun lamp $26.90
You mix and match what bulbs you want to run.
I would think that you'd want at least one Actinic, and a mix of the others. Up to you what you want to keep under the lighting, and the appearance you prefer when looking at your tank.
If you DO want to have some control over when your lights come on and off - meaning a dawn/dusk effect by using a couple timers - another option would be;
PFO 4 bulb VHO kit - 440 watts total
Includes ballasts, wiring harness and German end caps.
$169.95
Same goes for choice of bulbs as above.
If you go with URI bulbs - you will not need a reflector.
They have internal reflectors inside the lamp - that direct the lighting down into the tank.
A full length reflector is not necessary - but certainly would not hurt.
First option all for around $240.00
Second option all for around $270.00 + $20.00 for timers = $290.00
