Commonly called "Jelly Jars" due to their distinctive glass enclosure shape, Vapor Jar Lights are specialized fixtures designed to protect internal components from moisture, dust, and corrosive vapors. They are typically constructed with a heavy-duty metal housing (often cast aluminum) and a thick glass or polycarbonate "jar" that screws into a gasketed base, creating a hermetic seal.
If you notice water pooling inside your jar, the seal may have failed. While some users drill small drainage holes to prevent electrical shorts in failing units, this voids the "vapor tight" rating.
