The 295 g weight may provide advantages, such as increased durability. It may also allow for larger batteries, extending the runtime. A balanced flashlight has even weight. It can be more comfortable to hold for longer and reduce hand fatigue. The aluminum bodies can be anodized. This adds a protective layer and a wide range of color options for flashlight bodies. HAIII is a specific anodizing process. It creates a thicker and harder oxide layer than regular anodizing. This flashlight offers many color options. You can choose from a wide range of hues. They will suit your style and preferences.

Luminus is a US-based LED manufacturer. In the lighting industry, it has gained recognition as reputable. Color temperature is a characteristic of light. It is used to quantify the color appearance of light sources. Flashlights use the smooth reflector when long-range light is important. This includes searchlights and thrower flashlights. The AR coating on the lens maximizes light transmission. This makes the flashlight more effective in darker environments. The flashlight has electronic switches. They have many benefits and extra features compared to mechanical switches.

The 2400 lm output of FT03 SST40 provides great flexibility. You can adjust the brightness to fit different needs. 190000 cd represents an extremely high level of brightness for a flashlight. The throw distance is the farthest distance the flashlight can light an object. The cd/lm factor is the candela-to-lumen ratio. It shows how concentrated a light source's output is.

NarsilM firmware includes thermal regulation. It monitors and adjusts the flashlight's output based on temperature. The flashlight has mode memory. It remembers the mode you were using when the light was last turned off. It stays in that mode when you turn it on again. The light doesn't have predefined brightness levels or fixed modes. Instead, the ramping mode lets you adjust the light smoothly within a specific range.

The FT03 SST40 flashlight has a strobe function. It produces a rapid, repetitive flashing of light. The SOS signal is commonly used in outdoor adventures or survival scenarios.

The Astrolux FT03 SST40 flashlight is powered by 1 x 26650 Li-Ion battery. A battery indicator lets users see the battery status. It helps them decide when to recharge or replace the battery. A flashlight's USB charger can be very useful. This is especially true in emergencies. In such situations, access to power outlets may be limited. The Low Voltage Protection helps save the battery's capacity. It stops it from reaching a critically low voltage.

The built-in thermal control adjusts brightness output to prevent overheating. The "7" in the IPx7 rating shows that the flashlight can survive being submerged in water. It can withstand a certain depth for a limited time without getting damaged.

Accessories, package contents

Package contents2 x spare o-rings
lanyard

When gripping the flashlight with the lanyard around your wrist, it gives a more secure hold. It also gives a more stable hold. Replacing worn or damaged O-rings helps a lot. It keeps up the flashlight's durability and performance.

According to the ANSI/NEMA FL1 Standard, we measure the performance of the FT03 SST40 flashlight 30 seconds after switching on the light. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
