|Emitter||Osram P9 CW LED|
|Color temperature||6500 K|
Osram LEDs are known for their high performance, energy efficiency, and reliability. They provide a range of options in terms of brightness, color temperature, color rendering, and beam characteristics to meet different lighting requirements. The choice of color temperature depends on the specific lighting application and personal preferences. The TIR lens of D1 consists of a single-piece lens made of a transparent material, typically acrylic or polycarbonate. Its shape and internal geometry are designed to achieve specific light distribution patterns, such as flood or spot beams, by manipulating the behavior of light rays. The D1 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.
The 1100 lm output of D1 provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. With 4200 cd, the D1 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. The candela per lumen (cd/lm) ratio can be used to determine if a flashlight has a spot or flood type beam. Well-focused spot beams can be over 100 cd/lm, tactical flashlights are typically between 20-100 cd/lm, and work lights are less than 10 cd/lm.
Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The D1 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. Strobe mode on D1 flashlight produces a rapid, repeated flashing of light. It can be used for signaling purposes, self-defense, or attracting attention in emergency situations. SOS mode of the D1 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.
|Battery||1 x 18650 Li-Ion battery|
|Impact resistance||1.5 m|
