The emitter of NU43 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 TIR lens of NU43 consists of a single-piece lens made of a transparent material, typically acrylic or polycarbonate. Its shape and internal geometry are designed to achieve specific light distribution patterns, such as flood or spot beams, by manipulating the behavior of light rays. The NU43 utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches.
Performance
| Flux | 1400 lm |
|---|---|
| Intensity | 3800 cd |
| Throw | 123 m |
| CD/LM factor | 2.71 |
The 1400 lm output of NU43 provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. With 3800 cd, the NU43 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. 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
| Modes | 5 + 2 modes |
|---|---|
| Mode memory | yes |
| Ramping mode | no |
| Strobe | no |
| 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 NU43 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. 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 NU43 flashlight is powered by integrated 3400mAh Li-Ion battery. The battery indicator lets you know when the battery is low, charging, or fully charged. The NU43 flashlight can be charged directly from a USB power source, such as a wall adapter, computer, power bank, or car charger. This allows for convenient and versatile charging options, as you can utilize various USB power sources to recharge the flashlight's internal 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 NU43 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 IP68 rating represents the level of protection against solid objects, specifically dust and foreign particles. It indicates that the NU43 flashlight, is fully protected against the entry of dust and other solid objects. The NU43 flashlight with IP68 rating can withstand being submerged in water beyond 1 meter for a prolonged period, typically specified by the manufacturer. The NU43 flashlight proudly boasts an exceptional impact resistance rating of 2 m.
