This was one of the reasons why we liked the Sun Jar hack. The low cost of creating the lights, plus the fact that you could decide on what exact color the lights would shine, makes made this a no brainer. The other great thing about creating your own Sun Jars was that you could choose the shape of the Mason Jar. We suggest frosted jars.If you don't feel comfortable about doing this hack yourself, then check out these Sun Jars. They are made by Mark Feldstein & Associates and they cost $11, which is once again half of what the original Sun Jars cost. There are also special types of solar lights that require less work for you when you want to simply assemble your own Sun Jar. These lights can be found at any hardware store. The Westinghouse solar lights have a self-contained solar unit, which requires less work than before. Other brands will do as well, but you need to make sure that the solar unit is self-contained and that there aren't any wires going off into the rest of the light. All that's required is to glue this unit to the lid of an IKEA SLOM jar. The SLOM jars are inexpensive and quite compact, so they work very well. That's basically it. Naturally, you still need to apply frosting to these jars, but you can quickly see that many different kinds of jars will work with this hack.
