We are sorry to hear that you are disappointed with the lights. When fully charged, the lights produce a decorative 9.7 lumen light output. If you require a bright light output, we would suggest low voltage lighting as an option. For optimal performance, the lights should be located in an area that receives full, direct sunlight for at least 8 hours per day. if you feel the lights are not operating properly, 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.
