Bought 4 bulbs. NO worked in bathroom outlets. I ended up putting some solder on the pin as someone suggested in the review. It worked for three lamps but not one - I might damage it with a soldering iron. I contacted the seller and he sent me 4 new ones for FREE to replace the broken one. The new ones ended up with a bit more travel and ALL FOUR FOUND WITHOUT ANY ADJUSTMENT. Now I have 3 spares. All lamps are the same in appearance and color. I don't have dimmers so I can't criticize that aspect.
