Jennifer, I am not a expert on grow lights. I do use them. The light should state whether it is Full Spectrum and list the amount of Kelvin it has. My florescent bulbs are T5 High Output w 6400K. The full spectrum will cover most of the colors within light to assist with growth and vegetation. As I said I am not an expert and will not delve into the science of light.
The High Output florescent lights do come in a "pig tail" form also and not just 2', 4' tubes.
There are many different lights available, so check out yours first before spending any more money. A plane heat lamp will not give the right light.
