UL-listed: The e39 to e26 adapter has earned the UL Listed Mark. The adapter is made of metal and high-quality fireproof ceramic (unlike some cheap adapters made out of cardboard and bakelite). You can feel free to use it.

Application: Are you worried about not finding the right bulb for your antique fixture? This converter can solve your troubles！This socket converter can be used to convert a standard E39 Mogul size lamp to a lamp suitable for any medium (E26/E27). It fits any E26/E27 standard medium bulb.

Max Wattage: The maximum wattage is 660 watts and the voltage is 250V, allowing you to use a high wattage bulb. The adapter will not convert the voltage. If you have 110V, it will keep 110V. Likewise, 220V will not change. This adapter is only suitable for physical dimensions.

Easy to Install: The bulbs fit into the adapters very easily and each one of ours fits securely. Doing this enabled us to replace the old CFL's we had with something that is non-toxic and uses less electricity.
