Silicone sealed solar lights one year update.

It's a year since I experimentally sealed some solar lights with a thin layer of clear silicone sealant. It's very easy to do, but it's best used on metal or chromed solar panel surrounds as the silicone can peel from plastic.
The technique involves putting a plob of silicone in the middle of the solar panel and then placing a square of polythene/polyethylene plastic over the top and then squishing the silicone into a layer that covers the panel and surrounding bezel. Once it's had time to cure (usually just a day) then the polythene will just peel off leaving a solid film of silicone over the solar panel.
A test before and after showed that the silicone did not reduce the output from the solar panel.
One year later, including an unusually hot (too hot!) summer and a fairly grim winter, and the silicone looks as though it has handled the extremes of UV, heat and cold well.

One light did stop working though, and it's that one that is featured in this video.

There are many ways you can ruggedise standard solar garden lights against environmental extremes to make them last a very long time.
