No, a fluorescent light cannot work without its igniter. The igniter is an essential component in the operation of a fluorescent light fixture.
The purpose of the igniter is to provide the initial high voltage needed to start the electrical discharge in the fluorescent tube. When you turn on a fluorescent light, the igniter sends a high-voltage pulse to the electrodes at each end of the tube, creating an arc of electricity. This arc ionizes the gas inside the tube, allowing it to emit light.
Without the igniter, the electrodes in the fluorescent tube would not receive the necessary high voltage to initiate the arc, and therefore, the tube would not produce any light. The igniter is specifically designed to provide the required voltage and timing to start the fluorescent light properly.
If the igniter of a fluorescent light is faulty or damaged, it will need to be replaced in order for the light to function correctly.
