150 lm can provide a decent amount of brightness and be suitable for many everyday tasks, it may not be sufficient for certain scenarios or individuals with specific requirements. 628 cd can provide a reasonable level of luminous intensity for many everyday lighting tasks. The throw is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. The cd/lm factor (candela-to-lumen ratio) provides information about how concentrated or focused the light output of a light source is. A higher cd/lm ratio indicates that the light is more concentrated in a specific direction, while a lower ratio indicates a more diffused or spread-out light output.

The power source of the M20 flashlight is 1 x AAA battery, providing reliable and long-lasting energy for optimal performance. The M20 cannot charge batteries directly. You may need an external charger to keep your battery going. A protected battery is recommended as the light itself does not have low voltage protection (LVP). Flashlights without thermal protection may be more susceptible to overheating under extreme conditions, such as prolonged high-output use or exposure to high ambient temperatures. The "8" in the IPx8 rating indicates the highest level of protection against water ingress.
