Portable area lighting differs from other area lighting — it is smaller, lightweight, and runs on a sealed battery typically less than 14 volts. Portable area lights fill the gap between large, expensive generator-operated lighting and the need to have long-duration area lighting for smaller jobs with a need for rapid deployment and use in any weather. Portable area lighting is used for industrial maintenance, emergency response teams, highway construction and other applications.
Most portable area lighting uses LED lights due to the low consumption of energy required to operate the lights. The energy being consumed to power the LED is measured in watts. The amount of visible light or brightness produced by the LED light is measured in lumens. The amount of lumens in a given area is called the lux value. The LED’s lens will determine the shape of the light pattern which can vary from a flood to a spot pattern.
