Noctigon KR4 3000lm In-depth review, Pros and Cons
The Noctigon KR4 (KR4) released in 2020. It uses 4 x Luminus SST20 LEDs, TIR reflector and 1 x 18650 Li-Ion battery. The powerful emitter in this flashlight provides up to 3000 lm output, 18500 cd intensity, and a beam distance of 272 m.
The KR4 is a powerful and reliable flashlight. With its impressive illumination capabilities and durable construction, it serves as an exceptional lighting tool for various situations and environments. TIR technology minimizes hotspots, dark spots, and irregularities in the beam of KR4. 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.

Noctigon KR4 (KR4) specifications
Unlike ambient or overhead lighting sources, flashlights allow you to direct the light exactly where you need it.
|aluminium alloy with HAIII hard-anodized finish
The KR4 is small, compact, and designed for ultra-portability. A shorter flashlight is generally easier to carry in a pocket, bag, or pouch, making it more convenient for everyday use or when you're on the go. The aluminium body of KR4 has excellent thermal conductivity, meaning it can effectively dissipate heat generated by the flashlight's components. The body of KR4 flashlight treated with a Type III hard-anodized, anti-abrasive ﬁnish. The KR4 flashlight is available in assorted colors: black, cyan, gray.
|4 x Luminus SST20 LEDs
The US-based Luminus is recognized as a reputable LED manufacturer in the lighting industry. Color temperature is a characteristic of light. It is used to quantify the color appearance of light sources, particularly white light. The TIR lens of KR4 can minimize light loss and achieve high light output by capturing and redirecting a significant portion of the emitted light. Electronic switches on this flashlight provide a range of advantages and additional features compared to mechanical switches. The rear switch of KR4 is typically operated with the thumb or finger, making it easily accessible and convenient to use.
With 3000 lm, the KR4 flashlight will offer a brighter and more powerful beam of light. The KR4 flashlight with 18500 cd has an extended throw distance, allowing you to illuminate objects or areas at greater distances. 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 flashlight with a higher CRI can provide better color accuracy when examining objects or distinguishing between different colors in low-light or nighttime situations. The KR4 flashlight with a CRI of 95 offers the most accurate and true-to-life color representation, allowing you to perceive colors as they were intended to be seen.
The Anduril firmware is an open-source firmware developed for flashlights. It is designed to provide advanced control and customization options. 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 KR4 is tactical strobe ready. The strobe light is disorienting to the person it is aimed at which makes it difficult for them to concentrate. The SOS flashes Morse code so you can signal for help when needed.
|1 x 18650 Li-Ion battery
The Noctigon KR4 flashlight is powered by 1 x 18650 Li-Ion battery. The battery indicator lets you know when the battery is low, charging, or fully charged. The KR4 cannot charge batteries directly. You may need an external charger to keep your battery going. When the flashlight detects that the voltage of the battery has dropped to a certain threshold, it automatically reduces or cuts off the power output.
The built-in thermal control automatically adjusts brightness output to prevent overheating. The "6" in the IP67 rating represents the level of protection against solid objects, specifically dust and foreign particles. The "7" in the IP67 rating indicates that the flashlight, can withstand being submerged in water up to a certain depth for a limited time without being damaged. It has auxiliary LEDs which make it really nice looking.
The clip is useful to keep the light secured in your pocket.
The performance of the Noctigon KR4 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.
