Why do some lights flicker first before completely turning on?
In: Engineering
Yes the fluorescent tubes need ionised vapour or gas to operate….
It’s like electricity starts to conduct between two sides of tube but suddenly stops because the population of ions fall off….
The ionised gas upon conducting electricity gives some charge to fluorescent coating on the tube and we get light….
Till there is continuous replenishment of the charge the tube keeps on flickering….
And the choke and starter make sure the charge electricity and energy is continuously replenished to get light.
This involves little heating as well
