I’ve seen several examples of this, but each time the directions read to glue the light to the top of the jar.
Eventually the bulb is going to burn out – then what?
By Velcro-ing the light to the top of the jar you can replace the Solar Light when needed or just remove the Velcro and use the jar for it’s intended purpose.
Also, many people frost the inside of the jar, I highly suggest that. Just remember to leave a square at the top, the size of the solar panel, to let light in ….. or you know, it won’t work.
I didn’t frost the container because I wanted to take a picture of the inside of the jar, from the outside
