The bezel is the head of the flashlight. It’s an extremely important part, though it might seem like a minor or inferior aspect of the light. It holds the head of the light onto the body. This means it keeps the window of the flashlight in places and heightens the brightness of the light by way of keeping the microscopic lens firmly attached. Beneath the lens you’ll find the torch, and depending on the model, the batteries and everything else that makes the light work.
The lens is more than just a cover for the torch. It heightens the brightness and reach of the already powerful torch. A lens on a tactical flashlight is very important for a number of reasons.
It is used to protect the torch beneath, but also it is used to illuminate the area in a number of colors; red, green, blue or clear are generally the colors chosen by military groups. The different colors enhance or alter visibility in specific situations.
For example, a red lens will help to preserve night vision; blue helps in the tracking of blood trails; and green can enhance vision in light conditions.
LED bulbs generally are capable of about 50,000 hours of continuous use, which amounts to roughly 5 years.
They also have no filament, which makes them more shock resistant. These qualities make LED bulbs arguably the most reliable bulbs around, which is exactly what is needed for military, police, or any other user of military tactics.
LED lighting will provide the best possible vision no matter what the conditions are. The best LED flashlights are chargeable as well, meaning there is no need to carry a box of batteries around with you.
