Solar Motion Lights Offer An Affordable Outdoor Lighting Option
Solar motion lights supply a fantastic way of providing light to certain areas and increasing the security of your home. They consist of a passive infrared motion sensor, connected to a rechargeable (normally LED) light.
Excellent for yards, paths, drives and garages, solar motion lights require no external power source or maintenance and should keep working for many months before needing to be replaced. Not having to wire these lights to a power source means installation is really straightforward - you only affix the light, together with its solar panel and motion detector, to a suitable wall or post and that's it!
Solar motion sensing lights typically employ a number of bright LED lights to provide illumination. This is because they use very little power and will last for many thousands of hours without needing to be replaced. It is typical to find lights utilizing a cluster of up to 100 separate LEDs. 40 LEDs will produce around the same light as a 12 watt halogen bulb. They are also very safe, since no high voltages are required, and the LEDs generate no appreciable heat. If you need more powerful illumination, you can simply add more lights.
Nearly all solar motion lights make use of a separate solar panel to produce the power to charge the batteries contained in the unit. Because it's separate from the other components of the device, this means that you can locate it in the best place to receive maximum sunlight - this means you are able to place the light itself in a dimly lit area without encountering any problems. Even though most units are designed to be installed high up on buildings, etc., several are offered which employ posts which can be driven into the ground, providing a lower-level light.
Passive infrared detectors are the normal means employed by solar motion lights to pick up movement. You can position the sensor so it points to the most appropriate area. A 180 degree field of view is normal, and will detect movement out to at least 30 feet.
High-quality designs will allow you to set both the duration of illumination when the light is activated, and also the range at which movement is going to be detected. They'll also only switch themselves on when a certain level of darkness is reached, in order to avoid unnecessarily discharging the battery in during daylight hours.
