This bulb is ideal for lighting rooms and hallways where it is important to automatically have some light when it becomes dark without the need to physically switch on. This could be for security purposes where you would like a light to come on when you are not at home or for safety reasons where an area could become a hazard without any lighting.
This product is much more energy efficient than traditional lamps,It automatically switches ON at dusk and OFF at dawn and in contrast to other products this features 360 degree sensors to detect daylight from all angles.
In comparison to using timer switches this bulb will come on based on the low light level so there is no need for adjustments when the clocks go back or forwards. The bulbs uses the E27/E26 fitting so will fit into a standard socket without the addition of any other products.
Automation in the home can make every day task easier. When coming home at night to an dark house it can be more pleasant if a light has automatically been turned on.
