A solar power floodlight increases the security in remote parts of the garden where there is no electric power. Solar floodlights need to provide enough light for security, have motion detectors, and have separate panels of solar cells if in shaded areas.
1. Does the Floodlight Location Get Sun?
One of the primary reasons for selecting a solar security light is the lack of electrical lines in a particular location. If a location is dark enough to require security lighting, it could also be too shaded to power the battery in a solar-powered LED security light. If that is the case, it is sometimes necessary to purchase a solar panel connected by a long power cord. This makes it possible to place the solar panel where it receives optimal sun exposure while placing the security light where needed.
2. How Bright Is the Floodlight?
With LED floodlights offered as arrays of LED lights measured in lumens, direct comparisons to other kinds of lighting are challenging. A primary purpose of floodlighting is to startle intruders away, and the simple activation of the lights is often sufficient for doing that. The number of lights in the LED floodlight array is the easiest way to compare one solar-powered light to another. LED security lights with a single bright LED light source require electric power, and the battery duration of lights is important, particularly when used in areas with wandering pets that frequently trigger the lights. Battery life varies from less than an hour to several hours, based on a day of solar charging.
3. Is the Motion Detector Adjustable?
One of the best ways to conserve solar battery power is with a quality motion detector. A motion detector mounts on the floodlight unit or wires to it, and it turns the floodlight on when something moves within a specified distance or field of view. By allowing the floodlight to remain off when nothing is moving, a motion detector saves battery power. Motion detectors work by picking up on the infrared radiation, or warmth, of objects. When a passive infrared radiation, or PIR, motion detector 'sees' a moving object, it turns on the floodlight. Separate motion detectors are the best choice because they allow optimal positioning. Sensitive motion detectors sometimes activate when simple things like leaves pass in front of them, but some adjust to activate only when movement occurs within a certain distance or within a certain field-of-view adjustment. If the field-of-view is still too wide, heavy tape such as electrician's tape works to cover parts of sensors to reduce the viewing area.
