This high quality stainless steel pir post is fully automatic, wireless, and solar powered. Designed with two clever features to tackle our sometimes grim uk weather, one is the latest edge technology, enabling the solar panel to be doubled with a simple twist of the lid to increase the amount of sunshine it can harvest, and the other is the option to put in power save mode, meaning rather than staying on all night, it will only activate when motion is detected. In standard mode which is ideal for when there is plenty of sunshine hours, the light will be lit with a 5 lumen light as soon as it gets dark, and then increase to 50 lumen once motion is detected and stay bright for 15 seconds once motion has stopped. 63cm tall stainless steel pir post lightstandard mode light emits a gentle glow after dark and increases to full brightness when motion is detectedpowersaving mode light stays off after dark and illuminates to full brightness when motion is detectedhigh grade polycrystalline solar paneluses replaceable aa rechargeable batterieswireless and completely solar poweredautomatically detects motion at night and turns off automatically at dawnon off switch so it can be turned off at any point.can be installed in minutes no diy skills requiredstake mount supplied, but can be mounted to deckinglow voltage, safe to use year round outdoorsfull 1 year guarantee as standard
