Compact vs. VHO, Which way do I go?

I have a 90gal freshwater planted aquarium (24x48x18 HxWxD). I have 5
40watt NO T-12's, disabled down to three tubes. One of my
2-tube-ballasts has gone bad. It's a complete 2-tube Coral Life
system, so the ballast looks difficult/dangerous for me to change out.
Since I've never been happy with my watt/gallon ratio, it's time to do
some thinking...

Here's a decent price on a 3 VHO system:

In going from 40watt NO to 110 VHO, do the lumens change in the same
4:11 ratio? Is the 330 watts of VHO light equivalent to 330 watts of
NO light? Or am I putting out seriously more/less lumens per watt?

On the CF issue, I could go with four 65watt tubes using the DIY kit
at the same site:

It's a bit more pricy going this route. So what do I get with CF vs
VHO? Longer tube life? Less heat? More lumens per watt? I'm not
looking for space savings, I have a roomy slatted wooden hood with the
ability to install clips for any of the tubes I select.

The CF ballast indicates it can do 55 or 65 watt tubes. If I do CF,
how do these comparisons work:
200 NO watts vs 330 VHO watts vs 220(or 260) CF watts

Am I baking my plants at either of the VHO or CF configurations?

My plants are OK right now. I'd like to see them do a little better.
Fish are healthy. Algae under control. Pressurized CO2 system
running at a slow trickle.


Thanks for reading this far.
Bill.

P.S. I have access to sheet metal bending equipment. I can make my
own reflector to accomodate any tube configuration.
