Product advantages:
(1) Energy saving: Electronic ballast for fluorescent lamps uses more frequency of 20-60 kHz to supply power to the lamp, so that the luminous efficiency of the lamp is increased by about 10% compared with the power frequency (according to the length of the lamp of 4 feet), and its own power consumption is low, so that the total input power of the lamp is reduced by about 20%, and the energy saving effect is better.
(2) eliminating stroboscopic light, making light more stable: it is beneficial to improve visual resolution and efficacy; Reduce the visual fatigue of continuous operation, which is beneficial to protect eyesight.
(3) The starting point is more reliable: after the lamp is preheated, the starting point is successful once, avoiding multiple starting points.
(4) High power factor: The power factor of fluorescent lamps above 25W that meet the national standards is higher than 0.95. It should be noted, however, that the national standard has set a higher harmonic limit for lamps below 25W, so that its power factor is reduced to 0.7-0.8.
(5) Stabilize the input power and output luminous flux: High-quality products have good voltage stabilization performance, and can keep the light source power constant and stabilize the illumination when the power supply and voltage are quite different, which is beneficial to energy saving.
(6) Prolonging lamp life: Constant power of high-quality products, reduction of lamp current and reliable starting point can prolong lamp life.
(7) Low noise: The noise of high-quality electronic ballast can reach below 35db, and people can't feel the noise.
(8) Dimming: For places that need dimming, such as places where incandescent lamps or tungsten halogen lamps were originally used for dimming, replacing them with high-efficiency fluorescent lamps with dimmable electronic ballasts can achieve a wide range of dimming of 2%- 100%.
It should be noted that only a well-designed electronic ballast can give play to the above advantages. Although they are all electronic ballasts, the electronic ballasts used for metal halide lamps are much more complicated than those used for fluorescent lamps, or almost completely different. If the design or manufacturing process is not in place, a small omission will lead to failure.

The above is the introduction of electronic ballast manufacturers and their advantages. If we want to distinguish whether an electronic ballast is qualified or not, we only need to measure the voltage at both ends. If it is found that there is no high-frequency AC voltage output at the voltage output end, it proves that the electronic ballast is faulty, but this method is only suitable for the older inductive electronic ballast.
