Leviton. Designed for use with a wide variety of dimmable CFL light bulbs, the Decora CFL Slide Dimmer optimizes the performance of dimmable CFL bulbs. Unlike standard dimmers, which are not always compatible with dimmable CFLs, the CFL Slide Dimmer detects whether the bulb is an incandescent or a dimmable CFL, determines high- and low-end dimming capabilities, and adjusts the dimming range accordingly. The CFL Slide Dimmer helps eliminate problems dimming CFLs with standard dimmers, such as flickering or a small range of dimming. 800.323.8920. www.leviton.com.
