I'm playing with a Wien bridge sinewave oscillator and just characterised a small bulb to stabilise it. I was really surprised how sensitive the resistance was to applied voltage. I'm going to set the feedback resistor to 180R so everything should stabilise around 5V p-p. The opamp will peak at 10mA to drive it so everything should be fine.

The tungsten filament appears to have a temperature coefficient of 50C/mW so it will be running at around 200C.
