Everyone has different motivators for lighting upgrades. For industrial users still living with T12 fluorescent and magnetic ballast technology, the government will soon be mandating your move to more efficient lighting.
Note: T12 fluorescents and their corresponding magnetic ballasts are largely considered antiquated technology. So much so, that effective June 30th of 2010, you’ll no longer be able to purchase replacement magnetic ballasts to support those T12 lamps. That means you have less than one full burn cycle in your existing T12 lamps to make the shift to electronic ballasts.
