Hi Louises, Our Exeter has 3 different modes The first one is exactly what you are after
Mode 1: Light is set to remain at low brightness until motion is detected which activates high brightness for up to 15 seconds.
Mode 2: Light will only activate when motion is detected for up to 15 seconds [This is the best mode for winter].
Mode 3: Light is set to remain OFF.
Hope this helps
It comes with a bracket and a screw pack. That should help you secure the light on a hard surface such as the concrete base or pavement, driveway, etc.
