In auto mode the 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. This is an important feature, as dimming varies by bulb manufacturer, type and rating.

Previously, most dimmers were designed to work with incandescent or standard bulbs, but dimmable CFL bulbs do not work well with these standard dimmers. Additionally dimmable CFL bulbs now available in the marketplace have not been received favorable performance reviews from consumers.

“After using standard dimmers, consumers often report such problems as flickering when they dim the lights to lower levels, not being able to turn the lights on when the dimmer is in a dimmed position and limited dimming range when using CFL bulbs with these dimmers,” says Leviton director of residential marketing James Sherman.

“With the new Leviton Decora CFL Slide Dimmer, consumers can continue to enjoy the energy-saving benefits of dimmable CFL bulbs, but with improved ambiance and lighting options.”
