Body, materials, weight, colors

The flashlight weighs 17 g. It is lightweight and easy to handle for most people. A balanced flashlight has even weight. It can be more comfortable to hold for longer and reduce hand fatigue. The aluminium body of the GT Nano has a reputation for being durable and strong. It offers excellent resistance to impacts, scratches, and corrosion. The HAIII process makes a hard and wear-resistant surface on the aluminum. This makes it more resistant to scratches, abrasions, and impacts. The GT Nano flashlight is available in black.

System, LED, lens, reflector

People know Osram LEDs for their high performance, energy efficiency, and reliability. The color temperature choice depends on the light's use and personal taste. The smooth reflector creates a well-defined hotspot at the center. This hotspot provides a concentrated beam for long-range use. The coating is thin and applied to the lens surface. It cuts reflections and boosts light transmission. Some flashlights with electronic switches have programmable features. They allow users to customize the behavior of the flashlight.

Performance, flux, intensity, throw

450 lm can provide a decent amount of brightness and be suitable for many everyday tasks. The GT Nano flashlight has 23400 cd. It can light objects at greater distances. The throw is the 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.

Software, user interface, modes

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 GT Nano's ramping mode is easy to use. It lets you smoothly change the output over its whole range. The GT Nano 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.

Features, battery, protections

The GT Nano flashlight utilizes 1 x 10180 Li-Ion battery as its power source. 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. This flashlight has built-in low voltage protection (LVP). It prevents damage from over-discharge, so it doesn't need protected cells.

The GT Nano has thermal protection feature. These mechanisms track and regulate the flashlight's temperature as it operates. The "8" in the IPx8 rating means the highest level of protection. It is against water ingress. This flashlight has an impressive impact resistance rating of 1 m. It is built to endure accidental drops or impacts.

Accessories, package contents

The included battery lets you immediately use the flashlight for your desired applications. It saves time and allows you to focus on your tasks or activities. When gripping the flashlight with the lanyard around your wrist, it gives a more secure hold. It also gives a more stable hold. Instead of searching for matching O-rings, having spare O-rings allows quick fixes.

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