System

The emitter of SP33 manufactured by Cree, a US-based LED manufacturing company. Cree is a well-regarded LED manufacturer known for its high-quality products and innovation 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 SP33 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 SP33 utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches.

Performance

With 1080 lm, the SP33 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 8100 cd, the SP33 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

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The SP33 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 SP33 is tactical strobe ready. The strobe light is disorienting to the person it is aimed at which makes it difficult for them to concentrate.

You may need an external charger to keep your battery going. 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 built-in thermal control automatically adjusts brightness output to prevent overheating. The "6" in the IP68 rating represents the level of protection against solid objects, specifically dust and foreign particles. It indicates that the SP33 flashlight, is fully protected against the entry of dust and other solid objects. The "8" in the IP68 rating indicates the highest level of protection against water ingress.

Accessories
