Okay, I bought a 75w under the counter light from Walmart and the package says it is a "grow light" which is 75w output and uses 17w of energy. The only specks I can see for it are that it is rated 120V 60Hz 17W 300mA. So what I am wondering is would this work on my 37g tank and would I consider this as 2w per gallon and have enough to grow some plants in the tank?

What you bought is a 17W PC bulb/fixture whose output is roughly equal to that of a 75W incandescent bulb. Get another one lust like it and you'll be at ~1w/g. Start out w/ lowlight plants (Java anything, HM, Najas to mention a few).
The 2 watts per gallon guidline assumes you have flourscent lamps of some kind.
The 75W on the packet indicates it will replace a 75w incandescent lamp, but you have a 17w lamp there.
If it has the right tube (5,00 - 7,000K), and you get a couple more, then you are in the plant growing range.
