FAQ's Frequently asked questions

Will this adaptor change the type of bulb I can use?
It changes the bulb fitting so you can use a different bulb base. It does not change the voltage or wattage requirements of your light fitting.

Can I use this adaptor with any light fitting?
The adaptor is suitable where the existing socket is E40 and you want to use a E27 bulb. Always check that the bulb's wattage and dimensions are suitable for your light fitting.

Does the adaptor make my light taller?
Yes, the adaptor adds approximately 40mm to the height of the socket. This is worth considering if space around the bulb is limited.

Why don't you sell B22 to E27 adaptors?
We don't recommend B22 to E27 adaptors because converting a bayonet fitting to an E27 screw fitting can create a polarity issue. For safety, we recommend changing the lampholder rather than using an adaptor for this conversion.
