If you want more light to temporarily hold you over, do what I did:
Go to Wal-Mart or a local hardware store and buy a single-to-dual light socket splitter (found in the hardware department for just a couple bucks).
Then go over to the light bulb department and get two 100-watt equivalent fluorescent standard socket bulbs like these:

You'll be using less electricity with twice the output of one standard 100 watt bulb, and the light will be cast more uniformly in the garage since they face opposite directions.
