Overdriven fluorescents are truly impressive; one thing to remember, however, is that overdriven lamps produce much, much more heat than standard fluorescent bulbs. For this reason, it will be necessary to include in the aforementioned list of materials to purchase a fan, perhaps one like this

Failure to adequately cool your bulbs may lead to premature ballast failure and decreased bulb life. Otherwise, it's a great option.
