Using 18650 lithium ion rechargeable battery, the strong light flashlight enters the strong light mode when it is fully charged, and the initial illumination at the center of the spot 5m away from the light source should be greater than or equal to 180 1x. Its chromaticity coordinates should comply with the relevant provisions of white chromaticity area in GB/T8417-2003.

10. Strong light illumination time

18650 lithium-ion rechargeable battery is used. When the flashlight is fully charged, it enters the strong light mode and illuminates continuously for 300min. The illumination value of the center of the spot 5m away from the light source should be greater than or equal to 1001x.

11. Initial illumination of weak light

Using 18650 lithium ion rechargeable battery, the strong light flashlight enters the weak light mode when it is fully charged, and the initial illumination at the center of the spot 1m away from the light source should be 120 lx-~ 1801x.

12. Frequency of strong light explosion

The flash frequency of strong light flashlight should be 8Hz ~ 10Hz.
