To my understanding:

R1 is some kind of current limiting resistor. probably due to a to high voltage.

in the first stage, T1 is disabled, this means that T2 is enabled and current flows thru the lamp.
R2 and C1 form some kind of statupdelay.
when hitting a certain point T1 will flip over and switch of the lamp until the switch is pushed
