Features 3 modes of lighting: on the back of the unit there is a sliding switch with 4 positions1. Off. Unit off all of the time2. Uses the dusk to dawn sensor only, so the unit will come on at medium power when light levels drop and the lights will stay on as long as there is power in the batteries. Fully charged this will be several hours3. Uses dusk to dawn and pir motion sensor: at dusk the light will come on in low lode to provide basic lighting but if the sensor detects movement then it will switch to full power. If no further movement is detected then it will revert back to low power after 30 seconds4. Motion mode only: unit is off all the time unless it sees movement then the light will come on full power for 30 seconds. It will stay on as long as there is movement, then go off after 30 seconds.Specifications: Solar panel: 1W/5.5V Wattage:5.5W Lumen:550lm LED Quantity: 66 pcs Waterproof Grade: IP65BATTERY: 1 x 18650 2200mAh Lithium Battery (Customer replaceable with care - Remove the 5 small screws on back of unit and then the back cover can be carefully prised away - the battery can then be replaced with a good quality 18650 Li-Ion rechargeable type which should be easily found.
