Sofirn SF47T specifications

Flashlights let you navigate in the dark. They help you find supplies and signal for help. They also provide comfort and security in tough times.

Body, materials, weight, colors

Flashlights in this weight range (315 g) may have features. They include extended battery life, intense brightness, and rugged construction for heavy-duty use. The best flashlight size depends on personal preference. It also depends on intended use and the specific features you want. Aluminium is a lightweight material, which is beneficial for SF47T flashlight. The HAIII coating is often matte or textured. This finish improves grip and feels nice in the hand. This flashlight comes in a sleek black color option.

System, LED, lens, reflector

Osram is a German lighting manufacturer. It is a well-known and respected LED maker in the lighting industry. Color temperature is a characteristic of light. It is used to quantify the color appearance of light sources. Flashlights use the smooth reflector when long-range light is important. This includes searchlights and thrower flashlights. The AR coating of the lens helps to reduce these reflections. It does this by changing the lens surface's refractive index.

The SF47T uses multiple switches. The switches' placement and design determine this. They allow for one-handed operation. The flashlight has electronic switches. They have many benefits and extra features compared to mechanical switches. Mechanical switches often offer tactile feedback. Users can feel a distinct click or resistance when they press the switch. A simple press or click of the rear switch turns the flashlight on or off. This removes the need for complex button combinations or multi-step processes.

Performance, flux, intensity, throw

The 1500 lm output of SF47T provides great flexibility. You can adjust the brightness to fit different needs. 303750 cd represents an extraordinarily high level of brightness. The throw distance is the farthest distance the flashlight can light an object. The cd/lm factor is the candela-to-lumen ratio. It shows how concentrated a light source's output is.

Software, user interface, modes

A flashlight's modes are different output settings or brightness levels. They can be chosen to meet different needs and preferences. The flashlight has mode memory. It remembers the mode you were using when the light was last turned off. It stays in that mode when you turn it on again. The SF47T flashlight has ramping mode. Its user interface lets you control the brightness by pressing and holding a button.

Designers created the strobe function to produce a disorienting or attention-grabbing effect. The SOS code starts three short signals. Then, three long signals follow. Finally, there are three short signals again.

Features, battery, protections

The Sofirn SF47T flashlight is powered by 2 x 21700 Li-Ion batteries. The battery indicator prevents surprise power failures. It ensures the flashlight is ready when needed. The SF47T doesn't have charger port. LVP (Low Voltage Protection) is designed to protect the battery. It stops over-discharging, which can reduce battery life or cause permanent damage. The built-in thermal control adjusts brightness output to prevent overheating.

The flashlight has an IPx8 rating. It can withstand being submerged in water beyond 1 meter for a prolonged period. The manufacturer specifies this. The SF47T flashlight proudly boasts an exceptional impact resistance rating of 1 m.

According to the ANSI/NEMA FL1 Standard, we measure the performance of the SF47T flashlight 30 seconds after switching on the light. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
