We are sorry to hear that you are having this issue. Please make sure that the bulbs are screwed in completely and that the wiring is connected correctly. Also, make sure that the light is not connected to any type of dimming switch or remote. If the light is connected to a dimmer, the bulbs may flicker because the included bulbs are not dimmable bulbs. If the issue persists, please call Hampton Bay customer service at 1-855-HD-HAMPTON (1-855-434-2678) and one of the team members will be able to get more information to help troubleshoot and resolve the issue.
