Compatibility Chart

Leviton is proud to be a leader in the electrical industry by using the latest technology to develop products that
enhance daily living and help save energy. Sharing our knowledge and experience with you is an important part of
our brand promise to put our customers at the center of everything we do.
This report was developed to help you understand how to best pair today’s LED bulbs with Leviton dimmers so you
can locate the best combination to meet your lighting needs.
LED vs Incandescent Bulbs
Incandescent bulbs are rapidly being phased out in favor of longer-lasting,
more energy ecient LED bulbs. Because their circuitry is more complex,
not all LED bulbs will dim smoothly, and some may present other
inconsistencies such as flickering, slow start-up, limited dimming range
or inconsistent illumination.
Compatibility is Key
In order to achieve the best performance, it is important to ensure that the
LED bulb and dimmer you select are compatible when used together.
Existing dimmers in older homes are likely “Incandescent only” dimmers –
installed before LED bulbs became mainstream. Incandescent dimmers are
not rated for use with LED bulbs. Leviton recommends only using LED bulbs
with dimmers that are rated to control an LED load.
Testing for Compatibility
Leviton is dedicated to providing our customers with the best experience when using
Leviton dimmers. We work closely with LED bulb manufacturers and have a dedicated
team in our in-house lab that conducts ongoing testing of the latest LED bulbs/fixtures
with our LED dimmers to determine the best combinations.
This test program is designed to meet or exceed the latest testing criteria for evaluating performance of
LED bulbs with Leviton dimmers. We measure a number of factors including dimming range and irregular
functionality such as flickering or shimmering, slow start up, noise (humming/buzzing) levels and inconsistent
illumination. The testing is ongoing and results are updated regularly in our user friendly LED Compatibility
Selector Tool available at Leviton.com/led.
Understanding the Rating System
Our ratings will help you determine which bulbs/fixtures have been tested and approved as compatible with
Leviton LED dimmers. All results listed within this report are deemed compatible. The bulbs that display an
asterisk (*) after the model# are those that had exceptional performance and compatibility beyond our criteria.
