A lighting cover adapter for glass globe covers attaches to a glass globe cover around a bulb receiving opening of the glass globe cover with an internal globe plate and an external globe plate to secure the glass globe cover to a light fixture. A socket adapter is installed around a lightbulb socket. The internal globe plate is inserted through the bulb receiving opening and fastened to the external globe plate outside of the glass globe cover in order to secure the glass globe cover between the internal globe plate and the external globe plate. The glass globe cover is positioned around the lightbulb and the internal globe plate is then secured to the socket adapter through a spacing adapter in order to mount the glass globe cover to the lighting fixture.
