Verified Purchase(What is this?)
This review is from: Wanway B22 to E27 Socket Converter,BC to ES Extend Lampholder Base,Bayonet to Edison Screw Socket Adapter, for LED CFL Smart RGB Playbulb Music Light Bulb Speaker
The product does exactly what it says and works well.
It extends the length – of course — so the bulb may protrude.
It wasn't compatible with one of my lights because the adapter is a little wide, and my lamp has a long collar.
