Lumintop GT3 specifications

The GT3 flashlight allows you to light dark areas. It helps you find hazards or stop threats by shining light on them.

Body, materials, weight, colors

This 475 g flashlight is quite heavy for a handheld flashlight. A balanced flashlight has even weight. It can be more comfortable to hold for longer and reduce hand fatigue. The aluminium body of the GT3 has excellent thermal conductivity. This means it can effectively dissipate heat generated by the flashlight's components. The HAIII process makes a hard and wear-resistant surface on the aluminum. This makes it more resistant to scratches, abrasions, and impacts. The GT3 flashlight comes in a stylish black color.

System, LED, lens, reflector

Cree is a US-based LED manufacturer. It is well-regarded for its high-quality products and innovation in lighting. Color temperature is a characteristic of light. It is used to quantify the color appearance of light sources. The GT3 has a smooth reflector. The right reflector focuses light well. It gives you a better hotspot, and it throws better. The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. The flashlight has electronic switches. They have many benefits and extra features compared to mechanical switches.

Performance, flux, intensity, throw

Flashlights with very high lumen outputs demand a substantial amount of power. 85600 cd represents an extremely high level of brightness for a flashlight. The throw is the distance in meters at which the flashlight produces a light intensity of 0.25 lux. The cd/lm factor is the candela-to-lumen ratio. It shows how concentrated a light source's output is.

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 ramping mode has an advantage. It offers precise control over the light amount emitted by the flashlight. The GT3 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 Lumintop GT3 flashlight is powered by 4 x 18650 Li-Ion batteries. A battery indicator lets users see the battery status. It helps them decide when to recharge or replace the battery. The GT3 cannot charge batteries. You may need an external charger to keep your battery going. The flashlight detects when the battery's voltage has dropped to a certain level. Then, it reduces or cuts off the power. The built-in thermal control adjusts brightness output to prevent overheating.

The "6" in the IP65 rating shows the level of protection. It's against solid objects, like dust and foreign particles. The IP65 rating indicates that the flashlight has a protection against water jets. This flashlight has an impressive impact resistance rating of 1 m. It is built to endure accidental drops or impacts.

According to the ANSI/NEMA FL1 Standard, we measure the performance of the GT3 flashlight 30 seconds after switching on the light. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
