Leviton LED Dimmer & Bulb Compatibility Test Results

Leviton's LED Dimmer & Bulb Compatibility Test Results — an ongoing testing program that measures dimming range and checks for flickering/fluttering when popular LED bulbs are paired with Leviton's universal dimmers.

Testing and Compatibility

Leviton runs an ongoing program testing LED bulbs for compatibility with its universal dimmers, measuring dimming range and checking for abnormal flickering or fluttering. Bulbs are tested in quantities up to eight, since performance can vary with the number of bulbs being dimmed — ratings represent an average of observed readings and a reasonable expectation of real-world performance.

For consistent performance, use the same model and wattage of bulb when dimming multiple bulbs together. Mixing different bulb models/wattages can cause varied dimming levels, color shifts, and other undesired effects. The most current compatibility listings are maintained online at www.leviton.com/universal.

Understanding the Ratings

• Minimum Brightness Level — the lowest percentage the dimmer can reach with that bulb. Lower is better (wider dimming range).
• Performance — Better: Bulb will dim; some flickering may be present but is not significant and diminishes with manual slide adjustment.
• Performance — Best: Bulb starts at a low brightness floor with a dimming range similar to incandescent, with no observable flickering.

If a rating is not shown for a particular bulb/dimmer combination, it indicates inconsistent results or that testing data isn't yet available. The chart is updated regularly as new bulbs and dimmers are tested.
