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


Weight200 g
Length149 mm
Head diameter44.6 mm
Materialaluminium alloy with HAIII hard-anodized finish

The C8F LH351D generally comfortable to hold for extended periods and easy to carry in pockets or bags. The length of a flashlight can also impact its balance and weight distribution. A well-balanced flashlight, where the weight is evenly distributed, can be more comfortable to hold for longer periods and reduce hand fatigue. Aluminium is a lightweight material, which is beneficial for C8F LH351D flashlight.

The HAIII coating provides excellent corrosion resistance, protecting the underlying aluminum from exposure to moisture, humidity, and other corrosive elements. It helps maintain the appearance and functionality of the flashlight, even in harsh environments. This flashlight comes in a sleek black color option.

Samsung has a strong focus on research and development, continuously striving to innovate and improve their LED technologies. Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. The C8F LH351D features a smooth reflector (SMO). If long-range illumination and throw distance are the primary requirements, a flashlight with a smooth reflector may be more suitable.

The AR coating of the lens helps to mitigate these reflections by altering the refractive index of the lens surface. The C8F LH351D 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 C8F LH351D 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. The C8F LH351D 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 placement of the rear switch at the end of the C8F LH351D flashlight facilitates a secure forward grip. This grip allows for better control and handling of the flashlight, especially in situations where precision and stability are important.

Intensity20000 cd
Throw283 m
CD/LM factor6.67

The 3000 lm output of C8F LH351D provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. The C8F LH351D flashlight with 20000 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.

If accurate color representation is a priority for your specific needs, a flashlight with a CRI of 90 or above is highly recommended. The C8F LH351D with a CRI of 90 is beneficial in everyday use where accurate color perception enhances the overall visual experience. It can make colors appear more vibrant, natural, and distinguishable, allowing for a more immersive and enjoyable lighting environment.


Mode memoryyes
Ramping modeyes

The C8F LH351D 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 C8F LH351D flashlight with ramping mode has a user interface that enables you to control the brightness level by pressing and holding a button. The strobe function on the C8F LH351D 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 C8F LH351D has an SOS signal mode. The SOS code consists of three short signals, followed by three long signals, and then three short signals again.

The power source of the C8F LH351D 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.

The C8F LH351D 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. When the C8F LH351D 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 C8F LH351D 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 C8F LH351D flashlight with IPx8 rating can withstand being submerged in water beyond 1 meter for a prolonged period, typically specified by the manufacturer. With an impressive impact resistance rating of 1 m, the C8F LH351D flashlight is built to endure accidental drops or impacts, ensuring its resilience and dependable performance in demanding situations.


Package contents2 x spare o-rings

Regularly replacing worn or damaged O-rings helps maintain the overall durability and performance of the flashlight.

The performance of the Sofirn C8F LH351D 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.
