About this product


  • Converts Bayonet lampholder to Edison Screw
  • Black bakelite moulding
  • 250V AC

Product overview

• Converts Bayonet lampholder to Edison Screw
• Black bakelite moulding
• 250V AC
• Max 60W

To ensure full compatibility please check your lampholder before purchase, this adaptor converts a standard E27 bulb to work in a standard B22 light fitting. This product is not compatible with bayonets that have a safety feature which do not allow powering on without a bulb in place.

Rated 5 out of 5 by from BR TO ES ADAPTER BK70 I have been looking for these for two weeks and apart from ones dispatched in China with a 2 to 3 week wait I finally tracked them down in Maplin. Rang the store, had four put aside and collected same day. They fit perfectly, work perfectly and now mean I don't have to buy bayonet bulbs. Instead I can now use the ES LED bulbs I bought for decorating my ceilings for my outside lights when they go. Extremely pleased all round!!!

Rated 1 out of 5 by from Did Not Work Will not work with bayonets that have a safety pin that prevents switch on without bulb in place. No mention if this in description .

does this convert BC3 to screw? Or do you have a BC3 to B22 adaptor?

Asked by: bigwad00
On this occasion Maplin do not stock a product that exactly meets your requirements, or indeed anything close enough to offer you as an alternative.
