These lanterns are amazing and the dinner is bright. The only issue I had was the quarter twenty screw that attaches the lights to the brackets loosens and the lights wobble. I fixed it by removing the plastic cover covering the screw head. Then I pushed the screw all the way into the housing and applied a large bead to the screw head with Gorilla Clear Glue. The adhesive will self level and make the screws very strong after 24 hours exposure.
