Sofirn SC31B (SC31B) specifications
This Sofirn flashlight offers portability, versatility, and reliability in providing illumination.
|Head diameter||25.4 mm|
|Material||aluminium alloy with HAIII hard-anodized finish|
The 59 g flashlight would be considered extremely lightweight for a handheld flashlight. It's important to consider the length of the flashlight to ensure it fits comfortably in your desired carrying method. Aluminium is a lightweight material, which is beneficial for SC31B flashlight. The HAIII process produces a hard and wear-resistant surface on the aluminum, making it more resistant to scratches, abrasions, and impacts. This improves the overall durability of the flashlight body. This flashlight comes in a sleek black color option.
|Emitter||Luminus SST20 LED|
|Color temperature||6500 K|
|Lens||AR coated glass|
Luminus LEDs are known for their efficiency, brightness, color accuracy, and long lifespan. They offer a wide range of LED products with different characteristics to meet the diverse needs of the market. The choice of color temperature depends on the specific lighting application and personal preferences. The SC31B uses a smooth reflector. Unlike the textured surface of an orange peel reflector, a smooth reflector has a polished, mirror-like surface.
The AR coating of the lens helps to mitigate these reflections by altering the refractive index of the lens surface. The SC31B has electronic switch. Some flashlights with electronic switches have programmable features that allow users to customize the behavior of the flashlight. This may include setting specific modes, configuring brightness levels, or enabling unique functions according to individual preferences.
The 1000 lm output of SC31B provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. The SC31B flashlight with 10712 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. 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.
Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The SC31B 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. Strobe mode on SC31B flashlight produces a rapid, repeated flashing of light. It can be used for signaling purposes, self-defense, or attracting attention in emergency situations. SOS mode of the SC31B produces a specific sequence of long and short flashes to signal distress or emergency situations. It is commonly used in outdoor adventures or survival scenarios.
|Battery||1 x 18650 Li-Ion battery|
The SC31B flashlight utilizes 1 x 18650 Li-Ion battery as its power source. The SC31B has a battery indicator. A battery indicator is a feature that provides information about the remaining power level of the flashlight's battery. It helps users monitor the battery status and estimate how much runtime they have left before the battery needs to be recharged or replaced. The SC31B 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.
LVP (Low Voltage Protection) is designed to protect the battery from being over-discharged, which can lead to reduced battery life or even permanent damage. The SC31B 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 SC31B flashlight with IPx8 rating can withstand being submerged in water beyond 1 meter for a prolonged period, typically specified by the manufacturer.
The performance of the Sofirn SC31B 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.
