Actually I've had them, They are just shop lights that you can hang on the hood of your car or wherever when you are working on the engine. (shop lights)
I'm sure you can find them at somewhere like home depot, loews, etc.
Don't worry about the Ghetto Fab rig, you'll have fabulous results with it and then spend the money to get even better results only to figure out that no matter how much money you spend you will never match the results of your ghetto rig that you spent no money and little time on.
