Luminus is a US-based LED manufacturer. In the lighting industry, it has gained recognition as reputable. Color temperature is a characteristic of light. It is used to quantify the color appearance of light sources. Flashlights use the smooth reflector when long-range light is important. This includes searchlights and thrower flashlights. The AR coating of the lens helps to reduce these reflections. It does this by changing the lens surface's refractive index. The flashlight has electronic switches. They have many benefits and extra features compared to mechanical switches.

Bright flashlights are often larger and heavier. This is because they have more LEDs, better cooling, and bigger batteries. 1500000 cd represents an extraordinarily high level of brightness. The throw distance is the farthest distance the flashlight can light an object. The cd/lm factor is the candela-to-lumen ratio. It shows how concentrated a light source's output is.
