Ok...I found an cheap aquarium hood for my 20 gallon aquarium. I don't know if it includes a light. Does it?
Here's the pic and info:

That's not a lighting hood, it's a piece of glass that you put on top of your tank to slow down evaporation. The lighting hood goes on top of that.
Here's the section for lighting: http://www.drsfostersmith.com/product/pe t_supplies.cfm?c=3578+3733
Look for a 24" model, because 20 gallon tanks are 24" across.

Aquarium Limited Resources

It is ruinous, but this is not an inexpensive hobby. What you need to understand is that you have to stay within your resources. Because you have little funds, you need to be realistic as to what you can do and what you will be able to keep. Many of the gadgets and the kit we use are built especially for aquariums, and because of low volume sales, prices be biased to be higher. However, there are short cuts you can take, such as using equipment from other industries that can filch things a little bit cheaper.
For example, your reef aquarium lighting . You will be hard-hearted pressed to keep much in the way of corals with only one light. You will need at least two regular create fluorescent tubes, and even these will limit what you can keep to the hardier, less light-yearning species.
Doing things cheaper often means being superior to improvise, and sometimes you need to build your own equipment. In your case, you could acquire a simple 2-foot shop light fluorescent appendage for about $25, which you could suspend over your aquarium. Adding some light shades would point the light downward as opposed to all over the room.
For a better understanding the full aquarium lighting article explains that a watt is simply a measurement of energy NOT light output or even quality. Even comparable lumen output at the lamp is no longer a good measure of lighting parameter performance due to focus and restrike (as well as PAR & related useful light energy); a good example is a modern LED (such as the Aqua Ray ) which has a vastly higher useful lumen output than a comparable wattage CFL (such as a Current USA Compact Fluorescent) at 20 inches.
Another note with freshwater plant light requirements is that the 3-4 watts per gallon general rule applies to medium to high light plant requirements, not low light such as Java Moss, or in the case of Reef Aquariums stony corals such as Acropora.
Important Parameters to consider when choosing a light for your aquarium (not a complete list):
• Watts per gallon, • Lux, I generally only consider this parameter in deeper Reef and occasionally deeper planted freshwater aquarium to determine if I am getting the proper light where it needs to be.
Although still a popular measurement, the watts per gallon is part of the lighting equation as stated above is highly inaccurate when taken by itself. Taken together, the first FIVE points are the most critical (which does include watts per gallon), but no one of these should be a sole determiner of the lights.
As an example of the inaccuracy of the watts per gallon so-called rule, please consider these comparisons for an assumed 25 gallon aquarium: *20 Watt New Generation LED with an adjusted Kelvin temperature of 6500 K.
The T12 is going to be about 75% (or often much less) of the PAR of the LED with a lumens per watt output of 40 lumens per watt compared to 80 lumens per watt, the LED has at least 20% less wasted light energy to the yellow/green spectrum and finally the LED has 166% more focused lumens actually reaching the aquarium.
