The 95 g flashlight may not provide the same level of brightness or features as larger models, it can be handy for quick and convenient illumination in emergency situations or for close-range tasks. 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.

The aluminium bodies can be anodized, providing a protective layer and a wide range of color options for flashlight bodies. Anodizing enhances the corrosion resistance, hardness, and scratch resistance of the aluminum, while also allowing for a variety of attractive finishes. The HAIII coating can also enhance the visual appearance of the flashlight. It offers a uniform and attractive finish, often available in different colors, giving the flashlight a sleek and professional look. The PT40 SST20 offers an impressive assortment of captivating colors: black, desert tan.

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. This TIR lens offers flexibility in achieving various beam patterns, from wide-angle illumination to focused spotlights, depending on the specific design of the lens. The PT40 SST20 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.

Intensity2500 cd
Throw100 m
CD/LM factor0.83

The 3000 lm output of PT40 SST20 provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. With 2500 cd, the PT40 SST20 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 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.

Flashlights with a higher cd/lm ratio typically excel in long-range throw and focused beam applications, while flashlights with a lower cd/lm ratio may provide a wider and more evenly distributed beam for closer-range illumination or general-purpose use. If accurate color representation is a priority for your specific needs, a flashlight with a CRI of 90 or above is highly recommended. The flashlights with a CRI of 95 or higher are typically considered top-tier options and may come with premium features and components.

The power source of the PT40 SST20 flashlight is 1 x 18650 Li-Ion battery, providing reliable and long-lasting energy for optimal performance. The PT40 SST20 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 PT40 SST20 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 PT40 SST20 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 IPx6 rating indicates that the PT40 SST20 flashlight has a protection against water jets. It is recommended to handle flashlights with care and avoid subjecting them to unnecessary rough treatment to ensure their longevity and reliable operation. The PT40 SST20 flashlight effortlessly clings to metal surfaces, granting you the freedom to go hands-free and explore versatile mounting possibilities.
