WebNot having ground should not be a problem as GFCIs measure the power output from the hot to the input from the neutral lines. When the input is within a certain amount it then trips and shuts off the circuit. This then causes the GFCI to trip because of a short. If you replaced the switch then it may be a short in the fluorescent fixture. WebCold Cathode Fluorescent Lamps (CCFLs) are sealed glass tubes filled with inert gases. When a high voltage is placed across the tube, the gases ionize creating ultraviolet (UV) light. The UV light, in turn, excites an inner coating of phosphor, creating visible light. CCFLs have many desirable features, including: Excellent white light source.

Web14 oct. 2024 · The starter switch remains open. Once the gas inside the tube will get ionized by the kicked high voltage from the ballast when the starter switched off, all the current will start flowing through the glass tube of the Fluorescent lamp.
