DiCUNO E39 to E26 Adapter, Mogul E39 to Standard E26 Screw Base Light Bulb | Mogul E39 to Standard E26 Base Light Bulb Socket Reducer Converter, Maximum 200W, 165℃ Heat Resistant, Lamp Socket Adapter

These seem strong and well made. These are holding up a giant 8” corn cob bulb horizontally. They do not seem to give at all to the weight of the bulb. The top of the ring makes contact with the bottom of the bulb to lock it down which makes the best fit for the socket that I’ve seen. I’ve purchased two other ceramic versions of this and both have broken from the weight of the bulb (while installing the bulb).

Works well

These are great! I was able to convert some antique street lights into really cool floor lamps.

These are a good value. They are not the fanciest adapters, but they work good. I have used lots of them and have had no problems.

Retrieved from my deceased great aunt, an old but lovely 4 socket pole lamp. 3 bulb sockets took regular incondescent or LED bulbs but the one in the middle contained the largest 3-way light bulb I had ever seen with 100-200-300 WATT options. The Dicuno adapter screwed in easily and my regular bright light LED bulb works perfectly.
