Flashlights enable you to navigate in the dark, locate supplies, signal for help, or provide comfort and security in challenging circumstances.

Body

Flashlights in weight range of the SF47T (315 g) may have features like extended battery life, intense brightness, or rugged construction for heavy-duty use. The ideal length of a flashlight depends on personal preference, intended use, and the specific features and functionality you're looking for. Aluminium is a lightweight material, which is beneficial for SF47T flashlight. The HAIII coating often has a matte or textured finish, which enhances grip and provides a comfortable feel in the hand. This can be particularly useful in situations where a secure grip on the flashlight is essential, such as in wet or slippery conditions. This flashlight comes in a sleek black color option.

System

The emitter of SF47T 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. The smooth reflector is typically used in flashlights where long-range illumination is a priority, such as searchlights or thrower flashlights. By minimizing light scattering and maximizing light directionality, the smooth reflector can produce a tighter and more concentrated beam that reaches greater distances.

The AR coating of the lens helps to mitigate these reflections by altering the refractive index of the lens surface. The SF47T uses multiple switches. Depending on the placement and design of the switches, a multiple switch configuration can allow for one-handed operation. This is particularly helpful in situations where you need to hold or manipulate objects with one hand while using the flashlight with the other hand.

The SF47T utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches. The SF47T 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 SF47T is designed to be rugged and durable, capable of withstanding harsh conditions and repeated use.

Performance

The 1500 lm output of SF47T provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. 303750 cd represents an extraordinarily high level of brightness. 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.

Software

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The SF47T 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 SF47T flashlight with ramping mode has a user interface that enables you to control the brightness level by pressing and holding a button.

The SF47T is tactical strobe ready. The strobe light is disorienting to the person it is aimed at which makes it difficult for them to concentrate. It has the SOS beacon function for an emergency situation. The SOS flashes Morse code so you can signal for help when needed. The SOS signal is recognized as an international distress call and is used to indicate an urgent need for assistance.

Features

The Sofirn SF47T flashlight is powered by 2 x 21700 Li-Ion batteries. The battery indicator lets you know when the battery is low, charging, or fully charged. The SF47T doesn't have charger port. A charger port is a designated connection point or interface where you can plug in a charger to recharge the flashlight's battery. This flashlight has a built-in low voltage protection (LVP) to prevent damage to the cell from over-discharge, so protected cells are not necessary.

The SF47T 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 SF47T flashlight with IPx8 rating can withstand being submerged in water beyond 1 meter for a prolonged period, typically specified by the manufacturer. It is important to consider the impact resistance rating when selecting a flashlight, especially if you anticipate using it in situations where accidental drops or impacts are likely to occur.

The performance of the Sofirn SF47T 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.
