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.

The HA40 has mode memory. Mode memory means that the light will remember the mode you were using when the light was last turned off, and when you turn it on again. The HA40 is tactical strobe ready. The strobe light is disorienting to the person it is aimed at which makes it difficult for them to concentrate. It has the SOS beacon function for an emergency situation. The SOS flashes Morse code so you can signal for help when needed.

The HA40 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). The built-in thermal control automatically adjusts brightness output to prevent overheating.
