Color temperature	5000 K, 6500 K
Reflector	SMO
Lens	AR coated glass
Switch	electronic side

The emitter of SC31 Pro manufactured by Luminus, a US-based LED manufacturer. Luminus is recognized as a reputable LED manufacturer in the lighting industry. They are known for producing high-quality LEDs with excellent performance and reliability. 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 SC31 Pro has a smooth reflector. The properly focused smooth reflector gives you a more cohesive hotspot and therefore throws better. This flashlight has an AR coated lens. This Anti-Reflective coating is a thin optical coating applied to the surface of the lens to minimize reflections and improve light transmission. The SC31 Pro utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches.

Performance

Flux	2000 lm
Intensity	10000 cd
Throw	200 m
CD/LM factor	5

With 2000 lm, the SC31 Pro flashlight will offer a brighter and more powerful beam of light. This higher output can be advantageous in various situations where you require enhanced visibility or need to illuminate larger areas. With 10000 cd, the SC31 Pro 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 is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. The cd/lm factor (candela-to-lumen ratio) provides information about how concentrated or focused the light output of a light source is. A higher cd/lm ratio indicates that the light is more concentrated in a specific direction, while a lower ratio indicates a more diffused or spread-out light output.

Software

Firmware	Anduril
Mode memory	yes
Ramping mode	yes
Strobe	yes
SOS/Beacon	yes

The Anduril firmware is an open-source firmware developed for flashlights. It is designed to provide advanced control and customization options, offering a high degree of flexibility and functionality. The SC31 Pro 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 ramping mode of the SC31 Pro is intuitive, and lets you seamlessly ramp the output up and down over almost the entire output range.

The SC31 Pro is tactical strobe ready. The strobe light is disorienting to the person it is aimed at which makes it difficult for them to concentrate.
