First of all, remember that after you buy back the lamps, you should not be busy installing them. You should carefully look at the labels of the lamps and read the installation and application copy sheet, and then install and use the lamps according to the rules of the copy sheet, otherwise risks may occur.
Secondly, timely replace the aging lamp tube according to the light source parameters provided by the sign. If the two ends of the lamp tube are red, the lamp tube is black or there is a shadow, and the lamp tube cannot light up when it jumps, the lamp tube should be replaced in time to prevent the burning of the ballast and other unsatisfied phenomena;
Third, during clean maintenance, care should be taken not to change the structure of the lamp, nor change the parts of the lamp at will. After the clean maintenance, the lamp should be installed as it is, and no missing or wrong parts of the lamp should be installed;
Fourth, when using LED lamps, try not to switch them repeatedly, which will greatly shorten the service life of LED lighting.
