The emitter of LD42 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 LD42 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.

Intensity | 30625 cd |
Throw | 350 m |
CD/LM factor | 30.63 |
With 1000 lm, the LD42 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. The LD42 flashlight with 30625 cd has an extended throw distance, allowing you to illuminate objects or areas at greater distances. This can be advantageous for outdoor activities, search and rescue operations, or scenarios where long-range visibility is required.
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.
