Form	flashlight

This Manker flashlight is designed to be compact and handheld, making it easy to carry and maneuver.

Body

Weight	22 g
Length	133 mm
Head diameter	14 mm
Material	aluminium alloy with HAIII hard-anodized finish
Colors	black

The 22 g flashlight may not provide the same level of brightness or features as larger models, it can be handy for quick and convenient illumination in emergency situations or for close-range tasks. 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. HAIII coating is widely used in the flashlight industry due to its durability, corrosion resistance, improved grip, and aesthetic appeal. This flashlight features a captivating black color.

System

Emitter	Nichia 219C LED
Color temperature	4000 K
Reflector	OP
Lens	AR coated glass
Switch	mechanical rear

Nichia LEDs are often recognized for their consistent quality, durability, and adherence to industry standards. 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 PL21 Nichia 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 PL21 Nichia 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 PL21 Nichia 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	160 lm
Intensity	650 cd
Throw	51 m
CD/LM factor	4.06
CRI	90

If you mainly need a flashlight for basic tasks like finding keys, navigating in dimly lit areas, or occasional use around the house, 160 lm can be adequate. 650 cd can provide a reasonable level of luminous intensity for many everyday lighting tasks. 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. A flashlight with a higher CRI can provide better color accuracy when examining objects or distinguishing between different colors in low-light or nighttime situations. This can be beneficial in certain tasks or activities where color discrimination is important, such as identifying wires or reading color-coded information. The PL21 Nichia with a CRI of 90 is beneficial in everyday use where accurate color perception enhances the overall visual experience. It can make colors appear more vibrant, natural, and distinguishable, allowing for a more immersive and enjoyable lighting environment.
