4 Pack Solar Powered Mason Jar Lights - 30 LED Fairy Firefly Starry String Lights with Hangers, Waterproof Outdoor Hanging Lanterns for Garden, Patio, Wedding, Table Decor & Party Lighting

In my experience Mason jars had just a few major uses. Of course they were for canning fruits and vegetables, and in some places for drinking sweet tea or lemonade. As a kid we used them to hold lightning bugs for a while on a warm summer night. Now we use them for garden lanterns. What I like about these lights is that they are portable and bright enough to make them handy as lanterns to light up dark places when a flashlight isn't nearby. We keep one hanging near the doorway to light up the lock for our keys when the porch light is off. I gave Mom a set to hang from low garden hooks to light a pathway kept in shadows by other lights in the buildings around her yard. These are much brighter than the cheap stake-type solar garden lights. Each jar has a tightly bundled string of mini LEDs with a warm white glow--not that harsh cold LED white on other sets. You need to stretch the lights out and bundle them up into a loose ball to get them distributed evenly inside the jar. They look really nice hanging randomly around the garden too. I wished I had bought more than 4 because I kept finding spots I wanted to hang another one.The lights, jar lids , solar panels and battery compartments are separate from the glass part . If the glass cracks or breaks you should be able to get a standard Mason jar to replace it. Keep them in a place with enough sun to allow them to fully charge. If not in the right spot they'll slowly run down the battery. They automatically come on when the ambient light fades and shut off automatically when it increases. That means other lights nearby can make it so bright the jar lights will fail to come on or shut off too soon if you flip on a porch light or outdoor security lights.The only down side I found was a minor one that I hope was a fluke--one of the battery covers was missing. Fortunately the AA rechargeable battery fits tightly without it, so it was not a big issue.
