The Nitecore Ci7 (CI7) released in 2019. It uses 4 x Cree XP-G3 LEDs, 4 x SST10 IR LEDs, SMO reflector and 1 x 18650 Li-Ion battery. The powerful emitter in this flashlight provides up to 2500 lm output, 19500 cd intensity, and a beam distance of 279 m.

The Ci7 flashlight provides instant illumination at the touch of a switch. This immediate response is particularly useful in emergency situations or when you need instant visibility. This light has 5 + 3 modes of lighting. The mode memory of Ci7 eliminates the need to cycle through different modes every time you turn on the flashlight, providing convenience and saving time. The strobe function can be utilized as a self-defense tool, providing a non-lethal means to deter or disorient attackers

Nitecore Ci7 (CI7) specifications

The Ci7 flashlight enhances safety by illuminating potential hazards and improving visibility in low-light conditions.

Body

The Ci7 generally comfortable to hold for extended periods and easy to carry in pockets or bags. The ideal length of a flashlight depends on personal preference, intended use, and the specific features and functionality you're looking for. Aluminium body of Ci7 is known for its durability and strength. It offers excellent resistance to impacts, scratches, and corrosion, making it suitable for rugged outdoor use or in demanding environments.

The HAIII coating can also enhance the visual appearance of the flashlight. It offers a uniform and attractive finish, often available in different colors, giving the flashlight a sleek and professional look. The Ci7 flashlight is available in black.

System

Cree is widely regarded as a reputable LED manufacturer and has a track record of delivering high-quality and innovative lighting solutions. Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. The primary function of the smooth reflector (SMO) is to precisely focus and project the light emitted from the light source into a defined beam pattern. The smooth surface allows for greater reflectivity and light concentration, resulting in a more focused and intense beam with a longer throw distance.

This flashlight has an AR coated lens. This Anti-Reflective coating is a thin optical coating applied to the surface of the lens to minimize reflections and improve light transmission. The multiple switch configuration on the Ci7 flashlight can be a useful option, providing additional versatility and convenience in operating the flashlight. The Ci7 has mechanical switch. Mechanical switches are known for their durability and reliability. They are typically built with robust construction, making them resistant to wear and tear, and capable of enduring various environmental conditions. The rear switch of Ci7 is designed to be rugged and durable, capable of withstanding harsh conditions and repeated use.

Performance

With 2500 lm, the Ci7 flashlight will offer a brighter and more powerful beam of light. This higher output can be advantageous in various situations where you require enhanced visibility or need to illuminate larger areas. The Ci7 flashlight with 19500 cd has an extended throw distance, allowing you to illuminate objects or areas at greater distances. This can be advantageous for outdoor activities, search and rescue operations, or scenarios where long-range visibility is required.

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 higher cd/lm ratio indicates that the light is more concentrated in a specific direction, while a lower ratio indicates a more diffused or spread-out light output.

Software

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The Ci7 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 strobe function on the Ci7 flashlight is a feature that produces a rapid and repetitive flashing of light. It is designed to create a disorienting or attention-grabbing effect.

Features

The power source of the Ci7 flashlight is 1 x 18650 Li-Ion battery, providing reliable and long-lasting energy for optimal performance. Having a battery indicator on a flashlight is beneficial as it allows users to monitor the battery status and make informed decisions regarding recharging or replacing the battery. It helps prevent unexpected power failures during critical situations and ensures that the flashlight is ready for use when needed.

The Ci7 cannot charge batteries directly. You may need an external charger to keep your battery going. When the Ci7 flashlight detects that the voltage of the battery has dropped to a certain threshold, it automatically reduces or cuts off the power output to prevent further discharge. This helps to preserve the battery's capacity and prevent it from reaching a critically low voltage level. The built-in thermal control automatically adjusts brightness output to prevent overheating.

The "6" in the IP68 rating represents the level of protection against solid objects, specifically dust and foreign particles. It indicates that the Ci7 flashlight, is fully protected against the entry of dust and other solid objects. The "8" in the IP68 rating indicates the highest level of protection against water ingress. IR light falls outside the visible spectrum, making it invisible to the human eye under normal conditions.

Accessories

The package includes a holster to safely store your flashlight. When the flashlight is clipped to a suitable location, it can be angled or positioned to provide hands-free illumination. The lanyard of Ci7 helps protect the flashlight from accidental damage by preventing it from falling or hitting the ground. Having spare O-rings allows you to replace them as needed, ensuring that the flashlight maintains its water-tight seal and remains protected from moisture or water ingress.

The performance of the Nitecore Ci7 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.
