One other thing that should be pointed out is this: That little motor when given 12 volts, unloaded and running freely, draws about 54 or 56 mA, well within the max collector current of the small transistors, as you've shown. But at initial startup it will draw more, maybe a lot more, maybe enough to blow or stress the little transistors. Ditto if the motor is heavily loaded or stalled. The initial startup surge will be over quickly once the motor is running at speed so the transistors may survive even if the peak current is over their "absolute max" rating.
The surging you see in your video could be caused by a number of things but my first guess would be the power supply sagging. I'd also change the transistor just on spec.
You will find either mosfets, or BJTs inside the typical compact fluorescent bulb. I've seen both, and same brand bulbs may use either circuit. You can experiment with either type in this present motor circuit. You will usually find at least 4 diodes of the 1n400x variety or equivalent, the two transistors, a big electrolytic cap and some smaller film caps. I usually don't bother with the resistors or inductors in the CFL circuit but they too can be scavenged if you really need them for something. Be careful not to break the glass, there is a tiny amount of mercury inside.
