Flashlights enable you to navigate in the dark, locate supplies, signal for help, or provide comfort and security in challenging circumstances.


Weight125 g
Length112 mm
Body diameter26 mm
Head diameter37.5 mm
Materialaluminium alloy with HAIII hard-anodized finish

This 125 g flashlight would be considered slightly heavier than average for a handheld flashlight, but it is still within a reasonable weight range. A shorter flashlight is generally easier to carry in a pocket, bag, or pouch, making it more convenient for everyday use or when you're on the go. Aluminium is a lightweight material, which is beneficial for E07 SST20 CW flashlight. Hard-Anodized Type III (HAIII) is a specific anodizing process that creates a thicker and harder oxide layer compared to regular anodizing. This flashlight offers a wide array of color options, allowing you to choose from a diverse range of hues to suit your personal style and preferences.


Emitter7 x Luminus SST20 LEDs
Color temperature6500 K
Switchelectronic side

The US-based Luminus is recognized as a reputable LED manufacturer in the lighting industry. Color temperature is a characteristic of light. It is used to quantify the color appearance of light sources, particularly white light. The TIR lens of E07 SST20 CW consists of a single-piece lens made of a transparent material, typically acrylic or polycarbonate. Electronic switches on this flashlight provide a range of advantages and additional features compared to mechanical switches.


Flux4500 lm
Intensity15000 cd
Throw245 m
CD/LM factor3.33

With 4500 lm, the E07 SST20 CW flashlight will provide an exceptionally bright and powerful beam of light. The E07 SST20 CW flashlight with 15000 cd has an extended throw distance, allowing you to illuminate objects or areas at greater distances. The throw distance refers to the maximum distance at which the flashlight can effectively illuminate an object or target. The cd/lm factor (candela-to-lumen ratio) provides information about how concentrated or focused the light output of a light source is.

A flashlight with a higher CRI can provide better color accuracy when examining objects or distinguishing between different colors in low-light or nighttime situations. The CRI of 66 can still be sufficient for many general lighting applications where color fidelity is not critical.


Mode memoryyes
Ramping modeyes

Anduril allows users to customize various parameters, such as mode spacing, mode order, and shortcuts. Mode memory means that the flashlight will remember the mode you were using when the light was last turned off, and when you turn it on again. The E07 SST20 CW flashlight with ramping mode has a user interface that enables you to control the brightness level by pressing and holding a button. The E07 SST20 CW is tactical strobe ready. The strobe light is disorienting to the person it is aimed at which makes it difficult for them to concentrate. The SOS flashes Morse code so you can signal for help when needed.


Battery1 x 21700 Li-Ion battery
Battery indicatoryes
Charger portno
Thermal regulationyes

The Fireflies E07 SST20 CW flashlight is powered by 1 x 21700 Li-Ion battery. The battery indicator lets you know when the battery is low, charging, or fully charged. The E07 SST20 CW doesn't have charger port. LVP (Low Voltage Protection) is designed to protect the battery from being over-discharged, which can lead to reduced battery life or even permanent damage. The built-in thermal control automatically adjusts brightness output to prevent overheating.

The IPx6 rating indicates that the flashlight has a protection against water jets. It has auxiliary LEDs which make it really nice looking.


Package contentsclip
spare o-ring

With a clip, you can securely fasten the flashlight to a reachable location, ensuring it is easily accessible whenever you need it. The lanyard prevents accidental loss of the flashlight. Regularly replacing worn or damaged O-rings helps maintain the overall durability and performance of the flashlight.

The performance of the Fireflies E07 SST20 CW 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.
