there are two types of tube lights
1) with starter
2) without starter

1)for "with starter" the connection diagram is connect the
upper two pins of tube with two pins of starter and the
from lower two pins one is connected to the neutral wire
and the other is connected to the phase wire through choke.

function of choke is that when current changes due to
starter it produces a high voltage in 1000v range to ionize
the gas inside the tube according to the eq.
V=Ldi/dt
