!±8± Types of Motion Sensor Lighting

Motion sensor lights have become increasingly popular in recent times and with this increasing popularity different types of models are being designed and manufactured by companies on a larger scale. Essentially the design, make and principle of motion sensor lights is the same, they are different based on features such as use, type of power supply, types of lights employed and so forth. It was thought for a long time that these types of fixtures could only be used outdoors as part of complex security systems. It is now known that these lights can also be used indoor to illuminate dark hallways, corridors and stairways as these are economical and convenient. This is the first way to classify types of motion detector lights; whether they will be used outside the home for security or indoors for simple lighting purposes.

There are different types of fixtures depending on where you want to place them. Generally, lights to be attached on to ceilings, walls and in the yard are all distinct from each other in the complexities of their design and technology. Even with the differences all motion detector lights are incorporations of two basic parts; the light source and the motion detector. Placing models in categories based on the light source they have there may be those that have halogen bulbs and others which are installed with LEDs. Halogen bulbs or floodlights are standard, simple and easy to replace once their life runs out. Other pricier and high technology models have long lasting, built-in, durable and efficient light emitting diodes.

A more popular way to classify motion detection security lighting fixtures is the type of motion detectors that have been installed in them. Some have infrared sensors which turn the lights on when they are triggered by the heat of a person's body which they can efficiently sense. The other variety is ultrasonic sensors which steadily give out mute sound waves which have the property of reflection. This means that these rays can be reflected back by an object or person in their path and this serves as the trigger to turn on the light source. The third type of detector are microwave sensors which are essentially are based on the same principle as ultrasonic sensors but these use harmless microwaves to detect an obtrusion in their path.

Depending on their power source, these lights can also be categorized as those that use standard batteries or are run on solar power.
