Lumintop GT Nano 450lm In-depth review, Pros and Cons
The Lumintop GT Nano (GTNano) released in 2020. It uses Osram KW CSLNM1.TG LED, SMO reflector and 1 x 10180 Li-Ion battery. The powerful emitter in this flashlight provides up to 450 lm output, 23400 cd intensity, and a beam distance of 306 m.
The GT Nano flashlight is an essential tools for emergency preparedness. In situations like natural disasters or blackouts, when electricity is unavailable, a flashlight becomes crucial for navigating dark areas, locating supplies, or signaling for help. Instead of having to cycle through multiple modes to find the desired setting, mode memory of GT Nano ensures that the flashlight starts in the mode you prefer or need.
The strobe function of GT Nano produces a high-frequency flashing light pattern that is designed to disorient or distract potential threats or aggressors. The USB charger port allows you to charge your flashlight using alternative power sources, making them even more suitable for outdoor adventures or emergency situations where access to electricity may be limited.

Lumintop GT Nano (GTNano) specifications
Flashlights are compact and lightweight, making them highly portable. They can easily fit into pockets, backpacks, or glove compartments, allowing you to carry them wherever you go.
|Body diameter||14 mm|
|Head diameter||24 mm|
|Material||aluminium alloy with HAIII hard-anodized finish|
This 17 g flashlight would generally be considered lightweight and easy to handle for most people. 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. Aluminium body of GT Nano is known for its durability and strength. It offers excellent resistance to impacts, scratches, and corrosion, making it suitable for rugged outdoor use or in demanding environments.
The HAIII process produces a hard and wear-resistant surface on the aluminum, making it more resistant to scratches, abrasions, and impacts. This improves the overall durability of the flashlight body. The GT Nano flashlight is available in black.
|Emitter||Osram KW CSLNM1.TG LED|
|Color temperature||6500 K|
|Lens||AR coated glass|
Osram LEDs are known for their high performance, energy efficiency, and reliability. They provide a range of options in terms of brightness, color temperature, color rendering, and beam characteristics to meet different lighting requirements. The choice of color temperature depends on the specific lighting application and personal preferences. With the smooth reflector of the GT Nano, the beam tends to have a well-defined hotspot at the center, which provides a concentrated beam of light for long-range applications.
This flashlight has an AR coated lens. This Anti-Reflective coating is a thin optical coating applied to the surface of the lens to minimize reflections and improve light transmission. The GT Nano has electronic switch. Some flashlights with electronic switches have programmable features that allow users to customize the behavior of the flashlight. This may include setting specific modes, configuring brightness levels, or enabling unique functions according to individual preferences.
450 lm can provide a decent amount of brightness and be suitable for many everyday tasks, it may not be sufficient for certain scenarios or individuals with specific requirements. The GT Nano flashlight with 23400 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 is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. The cd/lm factor (candela-to-lumen ratio) provides information about how concentrated or focused the light output of a light source is. A higher cd/lm ratio indicates that the light is more concentrated in a specific direction, while a lower ratio indicates a more diffused or spread-out light output.
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 GT Nano 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 ramping mode of the GT Nano is intuitive, and lets you seamlessly ramp the output up and down over almost the entire output range.
Strobe mode on GT Nano flashlight produces a rapid, repeated flashing of light. It can be used for signaling purposes, self-defense, or attracting attention in emergency situations. SOS mode of the GT Nano produces a specific sequence of long and short flashes to signal distress or emergency situations. It is commonly used in outdoor adventures or survival scenarios.
|Battery||1 x 10180 Li-Ion battery|
|Impact resistance||1 m|
The GT Nano flashlight utilizes 1 x 10180 Li-Ion battery as its power source. The GT Nano has a battery indicator. A battery indicator is a feature that provides information about the remaining power level of the flashlight's battery. It helps users monitor the battery status and estimate how much runtime they have left before the battery needs to be recharged or replaced. This flashlight can charge the battery with an integrated charger, and it works with a USB power source.
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 "8" in the IPx8 rating indicates the highest level of protection against water ingress. The impact resistance of a flashlight can vary depending on its design, construction, and intended use.
|Package contents||10180 battery|
2 x spare o-rings
With an included battery you can immediately use the flashlight for your desired applications, saving time and allowing you to focus on your tasks or activities. When gripping the flashlight with the lanyard around your wrist, it provides a more secure and stable hold. Having spare O-rings allows you to replace them as needed, ensuring that the flashlight maintains its water-tight seal and remains protected from moisture or water ingress.
The performance of the Lumintop GT Nano 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.
