Type	U12
Rating	★★★★★ Rated 4/5 based on 1286 user votes.
Launch	2017
Form	flashlight

The presence of a flashlight can provide a sense of reassurance and confidence in unfamiliar or potentially dangerous environments.

Body

Weight	118 g
Length	112 mm
Head diameter	31 mm
Material	aluminium alloy with HAIII hard-anodized finish
Colors	black

This 118 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 the U12 flashlight can affect its 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 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. 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. This flashlight features a captivating black color.

System

Emitter	Cree XHP50.2 LED
Color temperature	4500 K, 6500 K
Reflector	OP
Lens	toughtened AR coated glass
Switch	electronic side

The emitter of U12 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 U12 has an OP reflector. The advantage of the orange peel (OP) reflector is that it can minimize glare and reduce eye strain, as the diffused light is gentler on the eyes compared to a focused, concentrated beam.

The AR coating on the lens maximizes light transmission, making the flashlight more effective in darker environments. The U12 utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches.

Performance

Flux	2000 lm
Intensity	6800 cd
Throw	165 m
CD/LM factor	3.4

The 2000 lm output of U12 provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. With 6800 cd, the U12 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 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 U12 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 U12 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.

Features

Battery	1 x 21700 Li-Ion battery
Battery indicator	yes
Charger port	USB Type-C
LVP	yes
Thermal regulation	yes
Protection	IPx8
AUX LEDs	no
Magnetic	no

The Manker U12 flashlight is powered by 1 x 21700 Li-Ion battery. The battery indicator lets you know when the battery is low, charging, or fully charged.

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 U12 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 U12 flashlight with IPx8 rating can withstand being submerged in water beyond 1 meter for a prolonged period, typically specified by the manufacturer.
