The first way: the old installation method is that there are springs on both sides. Push it aside a little hard and it will come out. The same is true when installing. Align the two terminals on one side of the lamp with the two holes on one side of the socket, and press hard to one side, and the lamp can be installed. The second way: torsion, that is, there are meetings on both sides. Put the lamp tube in the direction along that gap and twist it for half a week, and the lamp tube can be stuck.
