Review on Efficient E11 E26 E27 Candelabra Converter: Simplify Your Bulb Socket Conversions by Robert Ryokan

Actual length is closer to 3 inches or 76mm than 56.5mm as shown in one of the detailed images. The E11 fitting is usually designed for halogen bulbs, not decorative candelabra or night lamps. The difference is almost 10% Now the difference between e26/27 is also 1mm like e39 and 40 but they are usually interchangeable as the percentage difference is insignificant. A lot of the bad reviews are from those who bought because they thought that all sockets for candelabra are the same. Yes , it is longer than shown but in my case it is good.
