Lighting professionals trust Cree LEDs. Cree LEDs have gained a strong reputation for quality and performance. The color temperature choice depends on the light's use and personal taste. The smooth reflector creates a well-defined hotspot at the center. This hotspot provides a concentrated beam for long-range use. The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens.

The P18 flashlight has multiple switch options. They can be useful, adding versatility and convenience to using the flashlight. Some flashlights with electronic switches have programmable features. They allow users to customize the behavior of the flashlight. Mechanical switches are usually robust. They resist wear and tear and work in many environments. Rear switches are common on tactical flashlights. Law enforcement, military, and self-defense personnel use them.
