Astrolux FT03 SST40 (FT03SST40) specifications

Brand	Astrolux
Name	FT03 SST40
Type	FT03SST40
Rating	★★★★★ Rated 4/5 based on 1246 user votes.
Launch	2019
Form	flashlight

This Astrolux flashlight is designed to be compact and handheld, making it easy to carry and maneuver.

Body

Weight	295 g
Length	170 mm
Body diameter	34.5 mm
Head diameter	69.5 mm
Material	aluminium alloy with HAIII hard-anodized finish
Colors	black blue green

The 295 g flashlight would be considered moderately heavy for a handheld flashlight. The weight may provide advantages like increased durability or the ability to house larger batteries for longer runtime. The length of a flashlight can also impact its balance and weight distribution. A well-balanced flashlight, where the weight is evenly distributed, can be more comfortable to hold for longer periods and reduce hand fatigue.

The aluminium bodies can be anodized, providing a protective layer and a wide range of color options for flashlight bodies. Anodizing enhances the corrosion resistance, hardness, and scratch resistance of the aluminum, while also allowing for a variety of attractive finishes. 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	Luminus SST40 LED
Color temperature	5000 K, 5700 K, 6500 K
Reflector	SMO
Lens	AR coated glass
Switch	electronic side

The emitter of FT03 SST40 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 smooth reflector is typically used in flashlights where long-range illumination is a priority, such as searchlights or thrower flashlights. By minimizing light scattering and maximizing light directionality, the smooth reflector can produce a tighter and more concentrated beam that reaches greater distances. The AR coating on the lens maximizes light transmission, making the flashlight more effective in darker environments. The FT03 SST40 utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches.

Performance

Flux	2400 lm
Intensity	190000 cd
Throw	872 m
CD/LM factor	79.17

The 2400 lm output of FT03 SST40 provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. 190000 cd represents an extremely high level of brightness for a flashlight. 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. Flashlights with a higher cd/lm ratio typically excel in long-range throw and focused beam applications, while flashlights with a lower cd/lm ratio may provide a wider and more evenly distributed beam for closer-range illumination or general-purpose use.

Software

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

NarsilM firmware includes thermal regulation to monitor and adjust the flashlight's output based on temperature. This helps prevent overheating and ensures optimal performance and longevity of the flashlight. The FT03 SST40 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. Instead of having predefined brightness levels or fixed modes, the ramping mode lets you adjust the light intensity seamlessly within a specific range.

The FT03 SST40 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 26650 Li-Ion battery
Battery indicator	yes
Charger port	USB Type-C
LVP	yes
Thermal regulation	yes
Protection	IPx7
AUX LEDs	no
Magnetic	no

The Astrolux FT03 SST40 flashlight is powered by 1 x 26650 Li-Ion battery. The battery indicator lets you know when the battery is low, charging, or fully charged. USB rechargeable flashlights have become increasingly popular in recent years due to their convenience and sustainability. 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 FT03 SST40 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 "7" in the IPx7 rating indicates that the FT03 SST40 flashlight, can withstand being submerged in water up to a certain depth for a limited time without being damaged.

Accessories

Package contents	2 x spare o-rings lanyard

When gripping the flashlight with the lanyard around your wrist, it provides a more secure and stable hold. When using spare O-rings, it's important to follow the manufacturer's instructions and guidelines for proper installation.

The performance of the Astrolux FT03 SST40 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.
