WebA fluorescent lamp works by striking an arc between the two electrodes at the end of the tube. This arc passes through the gas that is filled inside the tube. The emissions from the arc hit the fluorescent coating on the inner surface of the tube to produce light. A high voltage is required to strike this arc. This is produced by the choke. http status 502: proxy errorWeb(i) A fluorescent lamp should start up with little blinking. Blinking indicates a defective starter, low voltage or a defective tube.
