Performance
| Flux | 5100 lm |
|---|---|
| Intensity | 180600 cd |
| Throw | 850 m |
| CD/LM factor | 35.41 |
With 5100 lm, the TK75 flashlight will provide an exceptionally bright and powerful beam of light. It can illuminate large areas, outdoor spaces, or even act as a temporary spotlight in certain situations. 180600 cd represents an extremely high level of brightness for a flashlight. 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.
