Microwave transformer ballast
I recently got a working microwave transformer for free, it has unknown wattage, though.
What's the best way to ballast it? Some people use lightbulbs, I'd rather not use lightbulbs cause that's almost as dangerous as the lightbulb it's self (I'm comfortable with the transformer, I'm not comfortable with a 500 watt lightbulb, ironic?)
No saftey speeches, please, lol.
