Review on 💡 CFL Spring Lamp - TCP 28942H41K 150W Equivalent (42W Actual) Cool White (4100K) Spiral Light Bulb with MOGUL Base by Christine Eads

The product was ok but my base was too narrow. Users should be aware that the diameter of the piston increases rapidly just above the bottom itself. This poses a problem with the vintage lamp, which was designed for a longer, thinner lamp shaft. In other words, the ceramic sleeve directly over the actual thread base prevented the male thread base from seating in the female portion of the bushing. So I need to use a mogul to medium base converter and switch to a medium base lamp. The company's customer service was helpful and quickly approved the return for me. They also carry basic transducers.
