The GT3 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. The memory function is a nice feature, the light will remember the last used mode. It has a strobe function, which is one of the most effective self defense tools available.

Lumintop GT3 (GT3) specifications

Brand	Lumintop
Name	GT3
Type	GT3
Rating	★★★★★ Rated 4/5 based on 1191 user votes.
Launch	2020
Form	flashlight

The GT3 flashlight enhance personal safety and security. It allows you to illuminate dark areas, identify potential hazards, or deter threats by shining light on them.

Body

Weight	475 g
Length	130 mm
Head diameter	68 mm
Material	aluminium alloy with HAIII hard-anodized finish
Colors	black

This 475 g flashlight is quite heavy for a handheld flashlight. The increased weight can provide advantages such as longer runtime, enhanced durability, and the ability to project a brighter and farther-reaching beam. 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 body of GT3 has excellent thermal conductivity, meaning it can effectively dissipate heat generated by the flashlight's components, such as the LED or battery. 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 GT3 flashlight is offered in a stylish black color.

System

Emitter	3 x Cree XHP70.2 LEDs
Color temperature	5000 K, 6500 K
Reflector	SMO
Lens	AR coated glass
Switch	electronic side

The emitter of GT3 manufactured by Cree, a US-based LED manufacturing company. Cree is a well-regarded LED manufacturer known for its high-quality products and innovation in the lighting industry. 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 GT3 has a smooth reflector. The properly focused smooth reflector gives you a more cohesive hotspot and therefore throws better.

The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. This can increase the overall brightness and efficiency of the GT3 flashlight. The GT3 utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches.

Performance

Flux	18000 lm
Intensity	85600 cd
Throw	585 m
CD/LM factor	4.76

The GT3 flashlight can produce 18000 lm output. Flashlights with very high lumen outputs demand a substantial amount of power. Ensure you consider the battery capacity, runtime, and rechargeability of the flashlight. 85600 cd represents an extremely high level of brightness for a flashlight. The throw is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. Candela per lumen (cd/lm) is a measure of a flashlight's beam intensity relative to its total luminous flux or output. It quantifies the concentration of light emitted by the flashlight in relation to the total amount of light produced.

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 GT3 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 advantage of the ramping mode is that it offers precise control over the amount of light emitted by the flashlight.

The GT3 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	4 x 18650 Li-Ion batteries
Battery indicator	yes
Charger port	no
LVP	yes
Thermal regulation	yes
Protection	IP65
Impact resistance	1 m
AUX LEDs	no
Magnetic	no

The Lumintop GT3 flashlight is powered by 4 x 18650 Li-Ion batteries. The battery indicator lets you know when the battery is low, charging, or fully charged. The GT3 cannot charge batteries directly. You may need an external charger to keep your battery going. 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 built-in thermal control automatically adjusts brightness output to prevent overheating. The "6" in the IP65 rating represents the level of protection against solid objects, specifically dust and foreign particles. It indicates that the GT3 flashlight, is fully protected against the entry of dust and other solid objects. The IP65 rating indicates that the GT3 flashlight has a protection against water jets. The impact resistance of a flashlight can vary depending on its design, construction, and intended use.

The performance of the Lumintop GT3 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.
