Body
Weight | 156 g |

Length | 143 mm |
Body diameter | 25.4 mm |
Head diameter | 40 mm |
Material | aluminium alloy with HAIII hard-anodized finish |
Colors | black |
This 156 g flashlight would be considered slightly heavier than average for a handheld flashlight, but it is still within a reasonable weight range. This weight range is often found in smaller and more compact flashlights designed for everyday use or portability. 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 bodies can be anodized, providing a protective layer and a wide range of color options for flashlight bodies. Anodizing enhances the corrosion resistance, hardness, and scratch resistance of the aluminum, while also allowing for a variety of attractive finishes. 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 features a captivating black color.

The emitter of Ci6 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 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 on the lens maximizes light transmission, making the flashlight more effective in darker environments. The Ci6 uses multiple switches. Depending on the placement and design of the switches, a multiple switch configuration can allow for one-handed operation. This is particularly helpful in situations where you need to hold or manipulate objects with one hand while using the flashlight with the other hand.
The Ci6 utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches. The Ci6 has mechanical switch. Mechanical switches often offer tactile feedback, allowing users to feel a distinct click or resistance when the switch is pressed. This feedback helps users confirm that the switch has been activated or deactivated, providing a reassuring sense of control and awareness. The placement of the rear switch at the end of the Ci6 flashlight facilitates a secure forward grip. This grip allows for better control and handling of the flashlight, especially in situations where precision and stability are important.
Performance
Flux | 440 lm |
---|---|
Intensity | 9000 cd |
Throw | 190 m |
CD/LM factor | 20.45 |
If you mainly need a flashlight for basic tasks like finding keys, navigating in dimly lit areas, or occasional use around the house, 440 lm can be adequate. With 9000 cd, the Ci6 flashlight provides a noticeably brighter and more intense beam of light. It can illuminate objects or areas with greater clarity and visibility, even at longer distances. 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. Flashlights with a higher cd/lm ratio typically excel in long-range throw and focused beam applications, while flashlights with a lower cd/lm ratio may provide a wider and more evenly distributed beam for closer-range illumination or general-purpose use.
Software
Modes | 5 + 5 modes |
---|---|
Mode memory | yes |
Ramping mode | no |
Strobe | yes |
SOS/Beacon | yes |
Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The Ci6 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 Ci6 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.

The Nitecore Ci6 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 Ci6 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.
This light does not have temperature control feature. The Ci6 flashlight with IPx8 rating can withstand being submerged in water beyond 1 meter for a prolonged period, typically specified by the manufacturer. Auxiliary LEDs are typically designed to consume less power compared to the main lighting source, such as a white LED. This energy-efficient feature allows for extended battery life, ensuring longer usage time before needing to recharge or replace batteries. Infrared photography or videography can produce unique and artistic results, capturing scenes with a surreal, otherworldly appearance.
