Body

Weight	2600 g
Length	318 mm
Head diameter	135 mm
Material	aluminium alloy with HAIII hard-anodized finish
Colors	black

The BLF GT94 flashlight is a bit heavy, its weight is 2600 g. It's important to consider the intended use and personal comfort when choosing a flashlight of this weight. The ideal length of a flashlight depends on personal preference, intended use, and the specific features and functionality you're looking for. Aluminium is a lightweight material, which is beneficial for BLF GT94 flashlight. Hard-Anodized Type III (HAIII) is a specific anodizing process that creates a thicker and harder oxide layer compared to regular anodizing. It involves subjecting the aluminum to a higher voltage and a sulfuric acid bath, resulting in a dense and durable coating. This flashlight comes in a sleek black color option.

System

Emitter	4 x Luminus SBT90.2 LEDs
Color temperature	5700 K
Reflector	SMO
Lens	AR coated glass
Switch	electronic side

The emitter of BLF GT94 manufactured by Luminus, a US-based LED manufacturer. Luminus is recognized as a reputable LED manufacturer in the lighting industry. They are known for producing high-quality LEDs with excellent performance and reliability. 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 smooth reflector is typically used in flashlights where long-range illumination is a priority, such as searchlights or thrower flashlights. By minimizing light scattering and maximizing light directionality, the smooth reflector can produce a tighter and more concentrated beam that reaches greater distances. The AR coating of the lens helps to mitigate these reflections by altering the refractive index of the lens surface. The BLF GT94 utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches.

Performance

Flux	20000 lm
Intensity	1500000 cd
Throw	2449 m
CD/LM factor	75

Flashlights with high lumen outputs are often larger and heavier due to the increased number of LEDs, advanced cooling mechanisms, and larger battery requirements. Consider the size and weight of the flashlight and whether it aligns with your intended use and portability needs. 1500000 cd represents an extraordinarily high level of brightness. The throw distance refers to the maximum distance at which the flashlight can effectively illuminate an object or target. The stated throw distance typically indicates the point at which the brightness falls below a specified threshold, such as 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. Well-focused spot beams can be over 100 cd/lm, tactical flashlights are typically between 20-100 cd/lm, and work lights are less than 10 cd/lm.

Software

Firmware	NarsilM
Mode memory	yes
Ramping mode	yes
Strobe	yes
SOS/Beacon	yes

NarsilM offers various customization options, allowing users to tailor the flashlight's behavior to their specific needs. This can include adjusting ramping profiles, configuring mode groups, setting shortcuts, and more. The BLF GT94 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 BLF GT94 flashlight with ramping mode has a user interface that enables you to control the brightness level by pressing and holding a button.

The BLF GT94 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	8 x 18650 Li-Ion batteries
Battery indicator	yes
Charger port	no
LVP	yes
Thermal regulation	yes
Protection	IP65
AUX LEDs	no
Magnetic	no

The Lumintop BLF GT94 flashlight is powered by 8 x 18650 Li-Ion batteries. The battery indicator lets you know when the battery is low, charging, or fully charged. The BLF GT94 doesn't have charger port. A charger port is a designated connection point or interface where you can plug in a charger to recharge the flashlight's battery. 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 BLF GT94 has thermal protection feature. The thermal protection mechanisms are designed to monitor and regulate the temperature of the flashlight during operation. This feature helps prevent overheating, which can be detrimental to the flashlight's performance, battery, and overall safety. The "6" in the IP65 rating represents the level of protection against solid objects, specifically dust and foreign particles. It indicates that the BLF GT94 flashlight, is fully protected against the entry of dust and other solid objects. The IP65 rating indicates that the BLF GT94 flashlight has a protection against water jets.
