About 50W LED Floodlight PIR

A 50W PIR LED Floodlight is a high powered security light typically used for outdoor applications. The use of an LED light in this product is to provide a more intense, reliable and longer lasting light when activated. An LED is a very energy efficient light and recent tests have shown several LED lights to have a run time of over 40,000 hours. They produce a more powerful light than a traditional bulb and do not have any warm up period which is essential in a security product. 50W refers to the power of the light and is measured in Watts. 50W is a high power and will produce a very intense light with a large range. PIR stands for passive infra-red and acts as a motion sensor to activate the light. All objects radiate heat and these sensors will pick up the infra-red signature of these objects. However, PIR is a motion sensor not a heat sensor. When there is a change in infra-red wave lengths being received by the sensor it will be recognised and the light will be activated. The sensitivity of the sensors can be changed to prevent activation from very small changes depending on the application it will be used for. Most 50W LED PIR floodlights are designed to be mounted on a wall or post. The brackets and fixings should come together with the light as will instructions on installation and positioning for optimal coverage. As they are typically used outdoors it is import to check that the product is fully waterproof. In most cases they will have a rubber seal to prevent any water damage.
