9W LED GLS Bulb with Dawn to Dusk Sensor - BC/B22, 2700K, Photocell

A modern bayonet LED bulb that can be used as a direct replacement to a traditional halogen bulb. Warm white in colour (2700 Kelvin), this uses only 9 watts to provide a bright lumen output of 810 lumens. This features a photocell which automatically turns the light on when it's getting dark and off again as it becomes light which is a perfect feature to use in outdoor lighting. Commonly referred to as dusk to dawn bulbs.
