Nitecore CU6 440lm review. Is it worth it in 2023?

The Nitecore CU6 (CU6) released in 2014. It uses 1 x Cree XP-G2 R5 LED, 1 x 365nm UV LED, SMO reflector and 1 x 18650 Li-Ion battery. The powerful emitter in this flashlight provides up to 440 lm output, 9000 cd intensity, and a beam distance of 190 m.

This flashlight has a wide range of applications across various domains. It is an indispensable tool for outdoor activities like camping, hiking, or night-time exploration, offering guidance and safety. This light has 5 modes of lighting. Lack of mode memory means you need to manually adjust the flashlight's settings each time you turn it on to get the desired mode. The strobe function can be utilized as a self-defense tool, providing a non-lethal means to deter or disorient attackers

Nitecore CU6 (CU6) specifications

The CU6 flashlight offers precise and focused illumination. Unlike ambient or overhead lighting sources, flashlights allow you to direct the light exactly where you need it.

Body

The CU6 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. The aluminium body of CU6 has excellent thermal conductivity, meaning it can effectively dissipate heat generated by the flashlight's components, such as the LED or battery.

The HAIII coating often has a matte or textured finish, which enhances grip and provides a comfortable feel in the hand. This can be particularly useful in situations where a secure grip on the flashlight is essential, such as in wet or slippery conditions. The CU6 flashlight is offered in a stylish black color.

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.

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 CU6 flashlight. The multiple switch configuration on the CU6 flashlight can be a useful option, providing additional versatility and convenience in operating the flashlight. The CU6 has electronic switch. The electronic switches may have a higher likelihood of standby drain compared to mechanical switches since they require a small amount of power for operation.

The CU6 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 CU6 is designed to be rugged and durable, capable of withstanding harsh conditions and repeated use.

Performance

440 lm can provide a decent amount of brightness and be suitable for many everyday tasks, it may not be sufficient for certain scenarios or individuals with specific requirements. With 9000 cd, the CU6 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 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

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The strobe function on the CU6 flashlight is a feature that produces a rapid and repetitive flashing of light. It is designed to create a disorienting or attention-grabbing effect. The CU6 has an SOS signal mode. The SOS code consists of three short signals, followed by three long signals, and then three short signals again.

Features

The power source of the CU6 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 CU6 cannot charge batteries directly. You may need an external charger to keep your battery going. When the CU6 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. Flashlights without thermal protection may be more susceptible to overheating under extreme conditions, such as prolonged high-output use or exposure to high ambient temperatures.

The "8" in the IPx8 rating indicates the highest level of protection against water ingress. Having separate auxiliary LEDs in a flashlight eliminates the need for additional lighting devices or filters. UV light is known to cause scorpions to fluoresce or emit a distinctive glow. For outdoor enthusiasts or individuals residing in scorpion-prone areas, a flashlight with UV capabilities can help locate and identify these nocturnal creatures more easily and avoid potential encounters.

Accessories

The holster provides a reliable and convenient way to keep your flashlight securely protected when not in use. When the flashlight is clipped to a suitable location, it can be angled or positioned to provide hands-free illumination. The lanyard of CU6 helps protect the flashlight from accidental damage by preventing it from falling or hitting the ground. Instead of searching for compatible O-rings or waiting for replacements to arrive, having spare O-rings readily available allows for convenient and immediate repairs or replacements.

The performance of the Nitecore CU6 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.
