The best lighting bang for your buck is the following:

Use what is called a T-5 5000 kelvin lamp/fixture. There are four high output t-5 lamps controlled by two ballasts. This is great for energy conservation as you can wire a two switch controller and bring in two switch legs to operate either two or four lamps depending on the need for light.
you can most likely get by with one on either side of the car and one in the front. If your bays are side by side, use one on the left, one in the center and one on the right.
Put in the appropriate number of fixtures at the front of the car depending on your needs.

They put out huge lumens and will take care of your need for "extreme" light when it gets dark.
I install these all the time and they cost about a hundred bucks each. A little pricey, but man, will you be happy!!
Leave me an email if you would like more info.
