I have just started a plant tank with my eclipse 37 gallon show tank. dimensions: 30 inches long by 23 or 24 inches height. Right now. my plants are not getting suffecient lighting. They are getting long without any leaves at the bottom (only leaves at the top) and some, such has my cambodia is thin and "whispy". I plan on tearing out the existing lighting and replacing it with either flourescent bulbs or tubes. I've read using several different types of bulbs is best; so maybe I'd combine daylight bulbs, full spectrum, and plant gro lights all in the same set up; trying to get around 100 watts. Am I along the right track? Any suggestions?

You could look into T5 power compact lighting.
You could get a 2x55 Watt fixture which is only 22 inches long so would fit inside any existing hood you may have. This should give you plenty of light for your plants!
There is an example of such a system here
It is about a quarter of the way down the page and has various lamps to choose from.
I believe that power compacts produce a lot more lumens per watt then standard fluorescents, so perhaps 110 watts would be too much for your tank? Hopefully somebody here will know more about power compacts than me! Very Happy

PC's put out a lot light than a NO fluorescent not per watt but over length.
Talking in lumens is very deciving a 6400K bulb(55W) puts out more than a 5300K bulb of the same wattage.

Having 110W of PC's on a 37G tank seems very appropriate, I had 55W PC + 20W NO on my 29G which is 4" shorter. When you add it up it's about 3wpg, if that counts for anything.
I would use a 6500K and a 10000K bulb, for best visual appeal (IMO)

Look at AH Supply for a DIY kit.
