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. The P20i has a smooth reflector. The right reflector focuses light well. It gives you a better hotspot, and it throws better. The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens.

The P20i flashlight has multiple switch options. They can be useful, adding versatility and convenience to using the flashlight. Mechanical switches are usually robust. They resist wear and tear and work in many environments. A simple press or click of the rear switch turns the flashlight on or off. This removes the need for complex button combinations or multi-step processes.
