IV. Let’s make things better
Unplugging the tube for replacement
Be Careful - IT'S HOT
Current tube technology requires high internal operating temperatures. As a result, the glass part of the
tube can reach temperatures as high as 250 degrees. Always allow your AX4B-533 Tube to sit switched off for
several minutes before you touch the tubes.
Incorrect ways of pulling up the tube:
1. Never hastily pull out the tube while lights is still
on: The fuse inside the tube could still be red with
high temperature when the power was just being
cut off. Therefore, if you pull out the tube
immediately right after power off, the possibility is
that you might not only be burnt by the high
temperature, but also caused a broken fuse by
violent shaking, and there goes the tube.
