(1) Energy saving. The electronic ballast of the fluorescent lamp is used to supply the lamp with a frequency of 20-60 khz, so that the luminous efficiency of the lamp is increased by about 10% than that of the power frequency (by a length of 4 feet), and the power consumption is low, so that the total of the lamp The input power is reduced by about 20%, which has better energy saving effect.

(2) Eliminate stroboscopic light and make the light more stable. It is beneficial to improve visual resolution and improve efficacy; reduce visual fatigue in continuous operation and help to protect eyesight.
(3) The starting point is more reliable. After starting the lamp, the starting point is successful and avoids multiple starting points.
(4) High power factor. Fluorescent lamps above 25W that meet national standards have a power factor higher than 0.95. However, it should be noted that the national standard specifies a high harmonic limit for lamps below 25W, so that its power factor drops to 0.7-0.8.
(5) Stable input power and output luminous flux: High-quality products have good voltage regulation performance. When the power supply and voltage deviation are large, the light source can maintain constant power and stabilize the illumination, which is conducive to energy saving.
(6) Extend the life of the lamp. The constant power of the high-quality products and the decrease in the lamp current, as well as the reliability of the starting point, can extend the life of the lamp.
(7) Low noise. High-quality electronic ballasts can reach noises below 35db, and people can't feel the noise.
(8) It can be dimmed. For places where dimming is required, such as the original dimming of incandescent or tungsten halogen lamps, high-efficiency fluorescent lamps with dimmable electronic ballasts can be used to achieve large-scale dimming from 2% to 100%.
It should be noted that only the well-designed electronic ballast can exert the above advantages. Although they are all electronic ballasts, electronic ballasts for metal halide lamps are much more complicated or almost completely different than those used for fluorescent lamps. If the design or manufacturing process is not in place, a very small omission will cause a malfunction.
