Use the right dimmer (ELV) to eliminate all buzzing
Reviewed in the United States on December 12, 2017
Great bright lights. Used 4 of the 4000K whiter lights in my kitchen to provide the equivalent of 400 watts. Looks and function perfectly. However, I tried the recommended dimmers in these reviews (and as noted on the box as compatible), but found only the "ELV" type to completely remove buzzing. I used the Lutron DVELV-300P.
ELV's look the same as others, but cost more (~$70 vs ~$30), and have an active line to electronically compensate for the buzzing that is otherwise evident in all conventional dimmers to varying degrees (by design concept).
It’sworth the extra cost for silence.
