The Smart Solar Sentinella PIR Bollard Light Set adds a convenient set of lights to outdoor walkways or driveways and illuminates only when needed. Each light contains 5 super-bright white LEDs. A PIR motion sensor is built into the first and last (sixth) light allowing bi-directional activation. The set automatically illuminates only when the PIR sensor is triggered to save energy. Each illumination lasts 30 seconds and a full charge can power up to 200 illuminations. A 10-foot cable connects the first light to the solar panel giving you some flexibility in choosing the perfect sunny spot. Each light is connected by five feet of cable.
