Performance
The throw is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. The candela per lumen (cd/lm) ratio can be used to determine if a flashlight has a spot or flood type beam. Well-focused spot beams can be over 100 cd/lm, tactical flashlights are typically between 20-100 cd/lm, and work lights are less than 10 cd/lm.
