Which statement is FALSE with respect to fluorescent lamps?

The statement that is identified as false is that the life of fluorescent lamps is not affected by the number of times the lamp is started. In reality, frequent starting can significantly impact the lifespan of fluorescent lamps. Each time a fluorescent lamp is turned on, it undergoes thermal and electrical stresses. This process can lead to a decrease in the number of operational hours the lamp will ultimately achieve.

Frequent starting can cause increased wear on the electrodes, which can lead to premature failure. Therefore, lamps that are turned on and off frequently will typically have a shorter life compared to those that are turned on and left to operate continuously. This makes it crucial to consider usage patterns when evaluating the expected lifespan of fluorescent lamps.

In contrast, the other statements regarding life being unaffected by ambient temperature, dimming, and line voltage are more accurate. While extreme temperatures can affect performance and dimming may alter output but not necessarily lifespan, the general consensus is that these factors pose less direct risk to the overall longevity of fluorescent lamps than frequent starting does.
