This E27 to B22 lamp base adapter converts a standard E27 screw socket to accept B22 bayonet bulbs, providing a simple retrofit for indoor fixtures.
Use it in table lamps, ceiling fixtures, or desk lamps to expand bulb options—LED, CFL, halogen and other B22-base lamps can be installed where only E27 sockets exist.
