Cold light drive also has several advantages as follows: (1) energy-saving. Its low power consumption, the decline in the total input power of the lamp line, better energy-saving effect. (2) the elimination of the strobe light-emitting more stable. It will help improve visual resolution, improve efficacy;reduce visual fatigue of continuous operation, help protect eyesight. (3) The starting point is more reliable. Once the starting point for success. (4) stable input power and output luminous flux: high quality products, good voltage regulation, power,voltage deviation is large, the light source constant power to maintain stable illumination conducive to energy conservation. .
