A buzzing sound may occur when Pulse is installed on a dimmer switch. If a dimmer switch is limiting the power being sent to the bulb, it will not operate as intended.
Additionally, LED bulbs are known to generate a “buzz” and FCC regulations dictate the acceptable levels of this noise. Pulse has been tested to perform well within the FCC’s limits. The noise level should not be noticeable from a distance of over 3 feet.
However, if you feel you have purchased a defective product, please contact our customer support team to help resolve the issue.
