Need help setting up lighting

I've been out of the hobby for over a decade but I ended up with a
great deal on a huge acrylic tank (79.5x18.25x24) that I just couldn't
pass up. However, I've never dealt with an acrylic tank before and
noticed that there are two "holes" cut out of the top piece for
lighting hoods (I'm assuming). These are 23x7. I am planning on setting
up a planted aquarium in this tank and need a lot of advice/help on
selecting the proper lighting. Is it even possible to provide enough
lighting using these two openings for a planted tank? If so, does
anyone have any suggestions on what I should get? Is there a pre-made
kit that would fit my needs? I've read in a couple of sites that I
should be using a combination of compact flourescent and metal halide.
Is this accurate? I'm not very knowledgeable about lighting and would
appreciate any help/advice anyone can give.

Thanks!
