1, cut off the power supply, hold both ends of the lamp tube at about 10 cm with both hands, and turn it clockwise for about half a turn.

2. Put two copper needles into the gap at one end of the lamp tube, so that the two clamping needles are on the same plane with the clamping plane. Pull gently with a little force to pull the two needles out of the gap, and then the other end can be pulled out.

3. The old electronic ballast has no gap, but it is elastic. Hold the plastic head on the right with your right hand, and push the lamp about 1cm to the right with your left hand. At this time, the needle on the left side of the lamp came out, and at the same time, the left hand went down away from the lamp holder, and then the left hand pulled the lamp to the left.

4. If it is an LED integrated fluorescent lamp tube (the bracket and the lamp tube are made into a whole), this means that there are two elastic clips to clamp the bracket, so it is necessary to break the elastic clips of the clips on the bracket base with a little force by hand, and then pull down the fluorescent lamp bracket with a little force.
