White laser is an illumination technology that uses monochromatic laser to convert into white light, which has the characteristics of high brightness and high collimation. So, what is the difference between a white laser flashlight and the white light we commonly see LED lights?

A white laser is light produced by stimulated radiation, which is realized by the principle of free photons inducing electrons at high energy levels. Compared with the traditional LED flashlight, the white laser flashlight has a stronger range and clearer edges, and the light is more concentrated. The advantages of low power consumption, high brightness, small size, high efficiency and practicality can be widely used in national defense, military, mountain search, sea and field search, forest fire prevention, fire fighting, rescue, patrol, etc. In addition, the high conversion efficiency, faster response speed, low energy consumption, and lower brightness attenuation of the white laser flashlight are also used in military lighting, traffic lighting, medical and special lighting. The characteristics of white laser are good focusing, long transmission distance, high brightness, good collimation and good light uniformity.

LED white light is the light produced by spontaneous radiation, which is realized by the principle of electron transition from a high energy level to a low energy level. The characteristics of LED white light are light divergence, large irradiation area, low brightness, good light uniformity, low relative laser cost, and long service life. LED white flashlight is brighter than white laser flashlight, mainly used for lighting, and the light is diffused.

But the white laser flashlight is a high-power light source, which is very dazzling, makes the human eye look uncomfortable, and may cause health hazards to the human body. Therefore, it is necessary to take corresponding precautions when using a white laser flashlight.
