After the low-quality energy-saving lamps are powered on, the brightness reaches a peak value, and the brightness is low and the light color is blue, which is pale and weak. A good energy-saving lamp will only reach normal brightness gradually after being lighted for a few minutes, while a high-quality energy-saving lamp will be bright and pure, and it will feel bright and fresh. Can use clean white paper near the lamp to block the light, see through the light color: poor quality energy-saving lamps are often very heavy blue, gray, purple and other variegated, generally good energy-saving lamps, lighter colors, top quality energy-saving lamps, white light is Very pure white, yellow is a very pure yellow, can not see the noise.
The darker the black end of the lamp tube near the bottom of the molded case, the smaller the range, the better the quality of the lamp. If a new lamp is dark, it will often affect its life.
