Convoy S21A (S21A) specifications
The S21A 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 diameter||26.6 mm|
|Head diameter||26.6 mm|
|Material||aluminium alloy with HAIII hard-anodized finish|
The S21A is small, compact, and designed for ultra-portability. The length of the S21A 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 body of S21A 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 can also enhance the visual appearance of the flashlight. It offers a uniform and attractive finish, often available in different colors, giving the flashlight a sleek and professional look. The choice of flashlight body color can be influenced by factors such as intended use, environment, personal style, and functional requirements.
|Emitter||Luminus SST40 LED|
|Color temperature||5000 K, 6500 K|
|Lens||AR coated glass|
Luminus has established a positive reputation as a reliable LED manufacturer, and their products are widely used and trusted by lighting professionals and enthusiasts alike. Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. The orange peel reflector of S21A is designed to improve the beam characteristics of the flashlight by diffusing the light emitted from the light source.
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 S21A flashlight. The S21A 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 S21A is typically operated with the thumb or finger, making it easily accessible and convenient to use. The positioning of the switch at the rear of the flashlight allows for natural and intuitive operation, particularly in one-handed scenarios.
With 2300 lm, the S21A flashlight will offer a brighter and more powerful beam of light. This higher output can be advantageous in various situations where you require enhanced visibility or need to illuminate larger areas. The S21A flashlight with 19600 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 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.
Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The S21A 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 strobe function on the S21A 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 S21A has an SOS signal mode. The SOS code consists of three short signals, followed by three long signals, and then three short signals again.
|Battery||1 x 21700 Li-Ion battery|
|Impact resistance||1 m|
The power source of the S21A flashlight is 1 x 21700 Li-Ion battery, providing reliable and long-lasting energy for optimal performance. The S21A cannot charge batteries directly. You may need an external charger to keep your battery going. When the S21A 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.
The built-in thermal control automatically adjusts brightness output to prevent overheating. The "8" in the IPx8 rating indicates the highest level of protection against water ingress. It is recommended to handle flashlights with care and avoid subjecting them to unnecessary rough treatment to ensure their longevity and reliable operation.
The lanyard prevents accidental loss of the flashlight.
The performance of the Convoy S21A 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.
