Description
Telecommunications, also known as telecom, is the exchange of information over large distances. It's a broad term that includes various sectors, but all include a transmitter and a receiver. The medium of signal transference can be via various means—fiber, electromagnetic fields, light, cable, etc. The high efficiency and directional nature of LED makes them ideal for many industrial uses. LED are increasingly common in street lights, parking garage lighting, walkway and other outdoor area lighting, refrigerated case lighting, modular lighting, and task lighting. A light therapy box mimics outdoor light. It's thought that this type of light may cause a chemical change in the brain that lifts your mood and eases other symptoms of SAD , such as being tired most of the time and sleeping too much. A tactical light is a flashlight used in conjunction with a firearm to aid low-light target identification, allowing the user to simultaneously aim a weapon and illuminate the target. The first and most important characteristic of a tactical flashlight is powerful brightness. Tactical flashlights are designed for law enforcement professionals and thus must be bright enough to disrupt the vision of another person so that they have to turn their head or shield eyes.
