Sofirn SP33 (SP33) specifications
Flashlights are compact and lightweight, making them highly portable. They can easily fit into pockets, backpacks, or glove compartments, allowing you to carry them wherever you go.
|Body diameter||31.5 mm|
|Head diameter||36 mm|
|Material||aluminium alloy with HAIII hard-anodized finish|
This 70.8 g flashlight would generally be considered lightweight and easy to handle for most people. It's important to consider the length of the flashlight to ensure it fits comfortably in your desired carrying method. Aluminium body of SP33 is known for its durability and strength. It offers excellent resistance to impacts, scratches, and corrosion, making it suitable for rugged outdoor use or in demanding environments.
The HAIII process produces a hard and wear-resistant surface on the aluminum, making it more resistant to scratches, abrasions, and impacts. This improves the overall durability of the flashlight body. The SP33 flashlight is available in black.
|Emitter||Cree XP-L HI LED|
|Color temperature||5500 K|
|Lens||toughtened AR coated glass|
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.
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.
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.
|Battery||1 x 18650 Li-Ion battery|
The Sofirn SP33 flashlight is powered by 1 x 18650 Li-Ion battery. The battery indicator lets you know when the battery is low, charging, or fully charged. The SP33 cannot charge batteries directly. 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.
|Package contents||2 x spare o-rings|
Attaching a lanyard to your SP33 flashlight provides an additional layer of security, reducing the risk of accidental drops or loss. Having spare O-rings allows you to replace them as needed, ensuring that the flashlight maintains its water-tight seal and remains protected from moisture or water ingress.
The performance of the Sofirn SP33 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.
