CF General Service Sensor

The CF General Service Sensor is a direct compact fluorescent replacement for incandescent general service lamps. These compact fluorescent lamps last up to 10 times longer, and are 80% more energy efficient, than their incandescent equivalents.

This lamp is a dusk till dawn lamp meaning that you don't have to worry about switching off your light when day light comes as the sensor will do it for you; likewise at dusk it switches on so it doesn't matter if you forget. Ideal for security situations such as when you go on holiday or for outside entrances.
