The E27 to B22 light bulb adapter lets you use B22 bayonet bulbs in fixtures with an E27 screw socket. It converts the E27 inner thread to a B22 outer bayonet, enabling more bulb choices without changing lamps or fittings.
Use it in table lamps, ceiling fixtures, floor lamps or for temporary testing during bulb selection. Suitable for DIY lighting swaps and situations where replacing the fixture is impractical.
