As other reviewers noted, the tube didn't fit our lamp. There are raised triangles at two corners of the nest. The original tube had cutouts that allowed the tube to go all the way in, but the replacement tube doesn't have those cutouts. I solved the problem by opening the top of the lamp and removing the locking triangles with needle nose pliers. It's pretty easy since the triangles are hollow. Note that the original tube can still go in, so removing the triangles doesn't affect how the pins go into the socket.
