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. Hard-Anodized Type III (HAIII) is a specific anodizing process that creates a thicker and harder oxide layer compared to regular anodizing. It involves subjecting the aluminum to a higher voltage and a sulfuric acid bath, resulting in a dense and durable coating. This flashlight features a captivating black color.

System

The emitter of H50 LH351D manufactured by Samsung, a Korean LED manufacturer. The choice of color temperature depends on the specific lighting application and personal preferences. 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 H50 LH351D has electronic switch. Some flashlights with electronic switches have programmable features that allow users to customize the behavior of the flashlight. This may include setting specific modes, configuring brightness levels, or enabling unique functions according to individual preferences.

Performance

The 2000 lm output of H50 LH351D provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. With 4700 cd, the H50 LH351D 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.

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 H50 LH351D 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. SOS mode of the H50 LH351D produces a specific sequence of long and short flashes to signal distress or emergency situations. It is commonly used in outdoor adventures or survival scenarios.

Features
