Luminous flux, light decay and light effect:

Luminous flux, luminous decay and luminous efficacy reflect whether an energy-saving lamp product has the effect of saving energy and whether it can meet the parameters stipulated by the national standard.

Because the energy-saving lamps use high-efficiency three-color phosphors, it is better to use water-coated powder coating technology, and its light efficiency can reach more than 60 lumens per watt. The 2000-hour light decay is controlled below 10%. Poor energy-saving lamps use what we often call halogen powder tubes. Because the halogen powder tubes use halogen phosphoric acid phosphor powder and organic powder coating technology, because its exhaust technology, raw materials, equipment and technical means are very backward, many of them are difficult to surpass. 1000 hours, according to the sampling inspection of some national mapping agencies, the initial luminous flux of a 9W halogen powder lamp is only 248Lm, and the luminous decay of 100 hours is as high as 23%; while the national standard stipulates that the luminous flux of compact energy-saving lamps can maintain 2000 hours The efficiency cannot be lower than 78%, and a high-quality energy-saving lamp has an initial luminous flux of 560 Lm, and after 5000 hours, it still maintains a luminous flux of 431 Lm.

Color tolerance, color rendering index, and color temperature consistency across batches:

Color tolerance, color rendering index and the consistency of color temperature of the whole batch of products reflect an important indicator of the light parameters of the energy-saving lamp capillary. From these indicators, we can see the purity of the manufacturer's tricolor phosphor, its technological level, and its technical level. The national standard stipulates that the color rendering index of energy-saving lamps with a color temperature of 6400K for tri-primary fluorescent lamps should be greater than 78, and the color tolerance should be less than 6; the color rendering index of energy-saving lamps with a color temperature of 2700K should be greater than 80, and the color tolerance should be less than 6; this level. Poor energy-saving lamps use poor phosphors and inconsistent processes, so the color tolerance of energy-saving lamps produced by them is greater than 15, and the color rendering index is less than 50. It is difficult for some commercial lighting to meet the requirements, especially in some large-scale In the occasions where energy-saving lamps are used, because of its low color rendering index and poor color temperature consistency, it looks almost dazzled.

Differences in raw materials and manufacturing processes of electronic ballasts:

Energy-saving lamps are very good because of their materials, processes, equipment and quality control methods. When we turn on the energy-saving lamps, we can see that the circuit board components are arranged in an orderly manner, and the appearance of the components is very good. Then look at the solder joints of the circuit board. It is consistent in size, full and glossy, and there is no phenomenon of solder joint virtual welding, false welding, and circuit board swaying. The circuit board components of poor energy-saving lamps are crooked. Due to the poor quality of the components, the appearance is not good.
