I have some G24 LED lamps, and have a problem with two types of\nsockets, the socket is not deep enough for the bulb to seat.\n\nThe bulbs are G24D, the sockets are G24Q , if that makes any\ndifference. One batch of sockets had a small post inside which I\ncould break off to allow the bulb to seat, the other socket wasn't so\neasily modifiable. The tail on the bulb measures about 22.5 mm. I\ncut the tail back to 18.5 mm and it works with the sockets.\n\nDo I have bad bulbs, sockets, or luck? Is there some standard\ndimension for this portion of the bulb?
