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 EC4S 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 EC4S 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 EC4S cannot charge batteries directly. You may need an external charger to keep your battery going. This flashlight has a built-in low voltage protection (LVP) to prevent damage to the cell from over-discharge, so protected cells are not necessary.
