Are dimming ballasts available for both fluorescent and HID lamps?

1. True

2. False

3. Only for fluorescent lamps

4. Only for HID lamps

The correct answer is: True

Dimming ballasts are indeed available for both fluorescent and HID (High-Intensity Discharge) lamps, which makes the statement true. The technology has advanced to allow for various types of dimming solutions tailored to specific lighting applications. For fluorescent lamps, electronic dimming ballasts provide flexibility in controlling light levels while maintaining efficiency and performance. Similarly, there are also specialized dimming ballasts designed for HID lamps, allowing for control over brightness levels, which can enhance energy efficiency and provide better light management in different environments. The availability of dimmable options for both types of lamps ensures that users can choose lighting solutions that fit their needs while also improving energy savings and extending the lifespan of the lamps by reducing output when maximum brightness is not required.
