How to Wire Instant Start Fluorescent Fixtures
Instant-start fluorescent fixtures use what is called an "instant start ballast" to cause fluorescent light bulbs to light immediately upon flipping the light switch without the delay experienced when using traditional fluorescent fixtures. Instant start ballasts work by sending an initial current to the bulb that is much higher (almost eight times higher) than the bulb's normal operating voltage of 120 volts. As long as you take proper electrical safety precautions, wiring an instant start fluorescent light fixture shouldn't be too difficult. Does this Spark an idea?

Connect the wiring in your instant start fluorescent fixture by matching the colored wires from your fixture to the colored wires coming from your home's electrical box. There should be a black, white, and a green wire coming from your home's electrical box and from your fluorescent fixture. Connect the black with the black, the white with the white, and the green with the green. You will need to use wire nuts to connect each pair of wires. Make sure that the wire nuts you use are the right size for the gauge and number of wires that you are using. Sometimes there is no green (ground) wire coming from light fixtures. When there is no green wire present you will need to connect the green (ground) wire from your home to the metal housing of the light fixture using the ground screw provided on the fixture itself.
