Why flurocent tubes flicker?
Ever wondered why this happens when you turn a flurocent tube on and when its about to blow?
Fluorescent bulbs are gas filled tubes, the gas is excited by electric pulses and in turn creates visible light; the device responsible for exciting the gas is called a ballast. Ballasts send pulses of electricity through the gas, rapidly turning the light on and off.
