Fireflies E01 (2019) review
The Fireflies E01 (E01) released in 2019. It uses Luminus SST40 LED, TIR reflector and 1 x 21700 Li-Ion battery. The powerful emitter in this flashlight provides up to 2300 lm output, 40000 cd intensity, and a beam distance of 400 m.
It uses a TIR lens to form the beam pattern. The memory function is a nice feature, the light will remember the last used mode. It has a strobe function, which is one of the most effective self defense tools available.

The emitter of E01 manufactured by Luminus, a US-based LED manufacturer. A TIR lens works on the principle of total internal reflection. The TIR lens collimates the LED light into efficient, well-controlled light beams that maximize the usable lumens in the target area.

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 E01 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 ramping mode of the E01 is intuitive, and lets you seamlessly ramp the output up and down over almost the entire output range. The E01 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 battery indicator lets you know when the battery is low, charging, or fully charged. The E01 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. The built-in thermal control automatically adjusts brightness output to prevent overheating.
