Fireflies E07 SST20 CW (E07SCW) specifications

Brand	Fireflies
Name	E07 SST20 CW
Type	E07SCW
Rating	★★★★★ Rated 3/5 based on 1093 user votes.
Launch	2019
Form	flashlight

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

Body

Weight	125 g
Length	112 mm
Body diameter	26 mm
Head diameter	37.5 mm
Material	aluminium alloy with HAIII hard-anodized finish
Colors	black gold gray silver

This 125 g flashlight would be considered slightly heavier than average for a handheld flashlight, but it is still within a reasonable weight range. This weight range is often found in smaller and more compact flashlights designed for everyday use or portability. The length of the E07 SST20 CW flashlight can affect its portability. 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. It involves subjecting the aluminum to a higher voltage and a sulfuric acid bath, resulting in a dense and durable coating. 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.

System

Emitter	7 x Luminus SST20 LEDs
Color temperature	6500 K
Reflector	TIR
Lens	TIR
Switch	electronic side

The emitter of E07 SST20 CW manufactured by Luminus, a US-based LED manufacturer. Luminus is recognized as a reputable LED manufacturer in the lighting industry. They are known for producing high-quality LEDs with excellent performance and reliability. Color temperature is a characteristic of light. It is measured in units called Kelvin (K) and 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. Its shape and internal geometry are designed to achieve specific light distribution patterns, such as flood or spot beams, by manipulating the behavior of light rays. The E07 SST20 CW utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches.

Performance

Flux	4500 lm
Intensity	15000 cd
Throw	245 m
CD/LM factor	3.33
CRI	66

With 4500 lm, the E07 SST20 CW flashlight will provide an exceptionally bright and powerful beam of light. It can illuminate large areas, outdoor spaces, or even act as a temporary spotlight in certain situations. The E07 SST20 CW flashlight with 15000 cd has an extended throw distance, allowing you to illuminate objects or areas at greater distances. This can be advantageous for outdoor activities, search and rescue operations, or scenarios where long-range visibility is required.

The throw distance refers to the maximum distance at which the flashlight can effectively illuminate an object or target. The stated throw distance typically indicates the point at which the brightness falls below a specified threshold, such as 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.

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. This can be beneficial in certain tasks or activities where color discrimination is important, such as identifying wires or reading color-coded information. The E07 SST20 CW may not provide the highest level of color accuracy. The CRI of 66 can still be sufficient for many general lighting applications where color fidelity is not critical.

Software

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

Anduril allows users to customize various parameters, such as mode spacing, mode order, and shortcuts, to tailor the flashlight's behavior to their specific needs and preferences. The E07 SST20 CW has mode memory. 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. It has the SOS beacon function for an emergency situation. The SOS flashes Morse code so you can signal for help when needed. The SOS signal is recognized as an international distress call and is used to indicate an urgent need for assistance.

Features

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

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. A charger port is a designated connection point or interface where you can plug in a charger to recharge the flashlight's battery. 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 E07 SST20 CW has thermal protection feature. The thermal protection mechanisms are designed to monitor and regulate the temperature of the flashlight during operation. This feature helps prevent overheating, which can be detrimental to the flashlight's performance, battery, and overall safety. The IPx6 rating indicates that the E07 SST20 CW flashlight has a protection against water jets. It has auxiliary LEDs which make it really nice looking.

Accessories

Package contents	clip lanyard spare o-ring

The clip is useful to keep the light secured in your pocket. 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.

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 Fireflies E07 SST20 CW, then don’t hesite and signal the problem to us.
