Which statement is FALSE with respect to compact fluorescent lamps?

The statement that two-pin compact fluorescent lamps (CFLs) can be dimmed is considered false. Typically, standard two-pin CFLs are designed to operate at full brightness and are not compatible with dimmer switches. Dimming capabilities generally depend on the design of the lamp and the ballast.

In contrast, four-pin CFLs sometimes have the capability to be used with dimming ballasts, allowing them to be dimmed under the right conditions. However, many integrated CFLs, which are self-contained and usually come with a specific ballast, do not allow for dimming regardless of their pin configuration. Thus, the assertion that most integrated CFLs cannot be dimmed aligns with common characteristics of these lamps.

Overall, the emphasis on the limitations of two-pin CFLs in relation to dimming is what makes that statement the false one.
