Sofirn IF25A 6500K (IF25A6500K) specifications
This Sofirn flashlight is designed to be compact and handheld, making it easy to carry and maneuver.
|Head diameter||35 mm|
|Material||aluminium alloy with HAIII hard-anodized finish|
The 99 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 affect how it feels in your hand and how you can grip and maneuver it. A longer flashlight may provide a more substantial grip, making it easier to hold and control, especially if you have larger hands.
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. Hard-Anodized Type III (HAIII) is a specific anodizing process that creates a thicker and harder oxide layer compared to regular anodizing. It involves subjecting the aluminum to a higher voltage and a sulfuric acid bath, resulting in a dense and durable coating. This flashlight features a captivating black color.
|Emitter||4 x Luminus SST20 LEDs|
|Color temperature||6500 K|
|Lens||toughtened 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 AR coating on the lens maximizes light transmission, making the flashlight more effective in darker environments. The IF25A 6500K has electronic switch. The electronic switches may have a higher likelihood of standby drain compared to mechanical switches since they require a small amount of power for operation.
With 4000 lm, the IF25A 6500K flashlight will provide an exceptionally bright and powerful beam of light. It can illuminate large areas, outdoor spaces, or even act as a temporary spotlight in certain situations. With 10000 cd, the IF25A 6500K 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.
If accurate color representation is a priority for your specific needs, a flashlight with a CRI of 90 or above is highly recommended. While the IF25A 6500K may not provide the highest level of color accuracy, a CRI of 70 can be sufficient for everyday use, such as outdoor activities, household tasks, or emergency situations.
The Anduril firmware has gained popularity among flashlight enthusiasts due to its versatility, ease of use, and the ability to customize flashlight behavior. The IF25A 6500K 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. Instead of having predefined brightness levels or fixed modes, the ramping mode lets you adjust the light intensity seamlessly within a specific range.
The strobe function on the IF25A 6500K 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 IF25A 6500K 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|
|Charger port||USB Type-C|
The power source of the IF25A 6500K flashlight is 1 x 21700 Li-Ion battery, providing reliable and long-lasting energy for optimal performance. Having a battery indicator on a flashlight is beneficial as it allows users to monitor the battery status and make informed decisions regarding recharging or replacing the battery. It helps prevent unexpected power failures during critical situations and ensures that the flashlight is ready for use when needed.
USB rechargeable flashlights have become increasingly popular in recent years due to their convenience and sustainability. When the IF25A 6500K 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 IF25A 6500K 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 IF25A 6500K flashlight with IPx8 rating can withstand being submerged in water beyond 1 meter for a prolonged period, typically specified by the manufacturer.
|Package contents||USB Type-C cable|
The performance of the Sofirn IF25A 6500K 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.
