The advent of LED technology and its widespread commercialisation for the light source has meant that it is now possible to produce a super-bright solar powered security light.
Security lighting generally needs two elements to be successful; 1) a bright enough light source to provide an adequate lighting distance for the application that it is being used for, and 2) a PIR (passive infrared) unit to automatically switch the light on when someone approaches in the dark.
PIR units normally have two main controls that can be adjusted. The sensitivity control determines how dark it must be before the light is activated. The duration control determines how long the light will stay on once activated.
