If the explosion-proof lamp tube flickers or does not work, it should be replaced in a timely manner. The specific replacement steps are as follows:

1. Firstly, cut off the power supply to prevent sparks from the replacement project. Remove the lampshade of the explosion-proof lamp and check whether the circuit or lamp tube of the explosion-proof lamp is damaged.

2. If the explosion-proof lamp does not work due to damage to the lamp tube, install this size to purchase a lamp tube for replacement.

3. To replace the lamp tube, first gently twist open the snap ring that fixes both ends of the lamp tube, remove the lamp tube, and replace the new lamp tube. The method is similar to when removing it. Align the two ends of the lamp tube with the place where the power is connected, and then fix the snap ring.

4. After replacing the lamp tube, clean the dust attached to the outside of the lamp body to avoid affecting the heat dissipation of the explosion-proof lamp and burning out internal electronic components.
