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 MK34 II SST40 NW uses orange peel (OP) textured reflector. The orange peel (OP) reflector is a specific type of reflector commonly used in flashlights. It is named after its distinctive textured surface, which resembles the skin of an orange.

The AR coating of the lens helps to mitigate these reflections by altering the refractive index of the lens surface. The MK34 II SST40 NW 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.

CD/LM factor1.55

With 17600 lm, the MK34 II SST40 NW flashlight will provide an exceptionally intense and blindingly bright beam of light. It can illuminate large areas, vast outdoor spaces, or even serve as a temporary spotlight in the darkest conditions. The MK34 II SST40 NW flashlight with 27225 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 MK34 II SST40 NW 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 strobe function on the MK34 II SST40 NW 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 MK34 II SST40 NW 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 MK34 II SST40 NW flashlight is 3 x 18650 Li-Ion batteries, 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 MK34 II SST40 NW 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 MK34 II SST40 NW 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 MK34 II SST40 NW 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 MK34 II SST40 NW flashlight with IPx8 rating can withstand being submerged in water beyond 1 meter for a prolonged period, typically specified by the manufacturer. It is recommended to handle flashlights with care and avoid subjecting them to unnecessary rough treatment to ensure their longevity and reliable operation.
