Advantages of LED slim vision chart light box:

1.       High brightness and light uniformly.Brightness contrast of each chart is uniform.

Make sure correct testing result.With red-green chart,astigmatism chart,honeycomb

chart and polarization chart.Test vision fast and correctly.

2.       Super power saving. LED photoelectric conversion efficiency reaches to over 80%.

The energy needed for the same light is about 10% of the traditional fluorescent lamp.

Even if the vision chart light box is working for 24 hours, power consumption is below 1 degree.

3.       Protect eyesight: DC drive, no flash(Normal lights are AC drive, it will inevitably

produce strobe).

4.       Health: Healthy light contain ultraviolet and infrared light, no radiation (ordinary

light contains ultraviolet and infrared).

5.       Green: no mercury,xenon or other harmful elements, and will not produce 

electromagnetic interference (ordinary lamp contains mercury and lead elements,

electronic ballasts will produce electromagnetic interference).

6.       Long life: life of up to 100,000 hours.

7.       Safety factor: safety voltage, current, and smaller, less heat, no security risk.

8.       Super slim,save room.
