Color temperature	6500 K
Reflector	SMO
Lens	toughtened AR coated glass
Switch	dual electronic side

Cree LEDs are commonly used in a wide range of lighting applications. Their products are trusted by lighting professionals and have gained a strong reputation for quality and performance. The choice of color temperature depends on the specific lighting application and personal preferences. The R40 uses a smooth reflector. Unlike the textured surface of an orange peel reflector, a smooth reflector has a polished, mirror-like surface.

The AR coating on the lens maximizes light transmission, making the flashlight more effective in darker environments. The R40 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

Flux	1000 lm
Intensity	67700 cd
Throw	520 m
CD/LM factor	67.7

The 1000 lm output of R40 provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. With 67700 cd, the flashlight will provide an intense and powerful beam of light that can illuminate objects or areas with exceptional brightness and clarity. 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.
