Fireflies E07 SST20 NW (2019) review

2019

7 x Luminus SST20 LEDs

3500 lm output

7106 cd intensity

1 x 21700 Li-Ion battery

The Fireflies E07 SST20 NW (E07SNW) released in 2019. It uses 7 x Luminus SST20 LEDs, TIR reflector and 1 x 21700 Li-Ion battery. The powerful emitter in this flashlight provides up to 3500 lm output, 7106 cd intensity, and a beam distance of 169 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.

System

The emitter of E07 SST20 NW 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.

Emitter	7 x Luminus SST20 LEDs
Color temperature	5000 K
Reflector	TIR
Lens	TIR
Switch	electronic side

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.

Flux	3500 lm
Intensity	7106 cd
Throw	169 m
CD/LM factor	2.03
CRI	95

Software

The E07 SST20 NW 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 E07 SST20 NW is intuitive, and lets you seamlessly ramp the output up and down over almost the entire output range. The E07 SST20 NW 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.

Firmware	Anduril
Mode memory	yes
Ramping mode	yes
Strobe	yes
SOS/Beacon	yes

Features

The battery indicator lets you know when the battery is low, charging, or fully charged. The E07 SST20 NW 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. It has auxiliary LEDs which make it really nice looking.

Battery	1 x 21700 Li-Ion battery
Battery indicator	yes
Charger port	no
LVP	yes
Thermal regulation	yes
Protection	IPx6
AUX LEDs	yes
Magnetic	no

Accessories

The clip is useful to keep the light secured in your pocket. The lanyard prevents accidental loss of the flashlight.
