All products have a service life. Even the stubborn substance, plastic, can be degraded for one hundred years, so we must pay attention to its service life when using a standard light source box, especially the life of its light source. We learn by Knowing that the light source is the core of the standard light source box.

The service life of ordinary fluorescent lamps ends when the lamps are not lit. However, due to the internal structure of the standard light source tube, which is different from ordinary fluorescent tubes, when it is used for 2000 hours, the color temperature, color rendering index, and brightness begin to decrease. At this time, although the tube can still light, it cannot be used as a standard light source. It must be replaced in time.

When the lamp tube is used overtime, the two ends will become black and aging. Replace the new lamp tube. After replacing the old lamp tube, reset the original use time to zero. Use a screwdriver to reach the CLR center hole and press the key.

Extend the service life of the lamp: within 1H of daily use, if you need to use it multiple times, please do not close the light box and turn it on again (because the lamp is turned on once is equivalent to 1H continuous use of the lamp). If you do not use the light box for a long time, please turn off the power (try to avoid repeatedly turning it on to extend the service life).

In fact, the life of the light tube of the standard light source box is not complicated, but it is different from our usual definition of the life of the light tube. Therefore, manufacturers must pay attention to this when using the light box, and do not wait until the light tube is off. The detected color may not be standard, and the loss may not be as small as replacing the standard light source box tube.
