The emitter of 5L2 manufactured by Cree, a US-based LED manufacturing company. The 5L2 has a smooth reflector. The properly focused smooth reflector gives you a more cohesive hotspot and therefore throws better. It has an AR coated lens.
|Emitter||5 x Cree XM-L2 LEDs|
|Color temperature||6500 K|
|Lens||AR coated glass|
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 5L2 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 5L2 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 5L2 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. This light does not have temperature control feature.
|Battery||3 x 26650 Li-Ion batteries|
|Impact resistance||1 m|
The performance of the Ultrafire 5L2 flashlight is measured according to the ANSI / NEMA FL1 Standard 30 seconds after switching the light on. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
The specifications above are based on the official data published by the manufacturer, but we also take user reviews into consideration. If you found an error or something lacking in the specifications above for the Ultrafire 5L2, then don’t hesite and signal the problem to us.
