The 58 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 ideal length of a flashlight depends on personal preference, intended use, and the specific features and functionality you're looking for. 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	3 x Osram KW CSLNM1.TG LEDs
Color temperature	6500 K
Reflector	TIR
Lens	TIR
Switch	mechanical rear

The emitter of TK18 AL Osram manufactured by Osram, a German lighting manufacturer. Osram is a well-known and respected LED manufacturer 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. This TIR lens offers flexibility in achieving various beam patterns, from wide-angle illumination to focused spotlights, depending on the specific design of the lens.

The TK18 AL Osram 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 rear switch of TK18 AL Osram is designed to be rugged and durable, capable of withstanding harsh conditions and repeated use.

Performance

Flux	1900 lm
Intensity	20500 cd
Throw	286 m
CD/LM factor	10.79

The 1900 lm output of TK18 AL Osram provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. The TK18 AL Osram flashlight with 20500 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 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	no

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The TK18 AL Osram 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 TK18 AL Osram is tactical strobe ready. The strobe light is disorienting to the person it is aimed at which makes it difficult for them to concentrate.
