Can a bare bulb lampholder light fixture be installed outdoors?
Tuesday, June 26, 2018
Most people don’t know that those inexpensive porcelain or plastic light fixtures for a bare bulb are called lampholders. We occasionally see them used as an exterior light fixture, like in the photo above, but there are three reasons why exterior installation is not acceptable or safe:
- Although lampholders are UL-approved, it is only for interior installation. They are not rated for exterior weather exposure.
- Most bulbs that fit the socket of a lampholder are also not rated for exterior use and may explode when wet.
- Some cities and counties have ordinances that do not allow bare bulb exterior light fixtures.
