the pictures there show exactly how I plan on wiring them, in series (right?).
I'm not sure exactly how many watts of power I need. It's going to be similar to the telescope dew...

I am trying to build a small circular heater (similar to a dew heater for a telescope) with resistors. Basically I have 22 gauge rated 300volts...
