It will provide an unparalleled level of brightness and visibility, capable of illuminating objects or areas with exceptional clarity even at very long distances.
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.
Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The T21 has mode memory. Mode memory means that the flashlight will remember the mode you were using when the light was last turned off, and when you turn it on again.
