E27 Dusk to Dawn Sensor LED Bulb 15W, Auto On and Off, Cool White

This E27 LED bulb has a small light sensor built into its body, so it switches itself on as daylight fades and off again when morning comes. It looks like a normal pear shaped bulb, about 135 mm tall, with a white plastic cover that spreads light over a wide 270 degree beam. It screws into any standard E27 socket, which makes it a simple way to add automatic lighting to an existing porch lamp, garden lantern or stair light without new wiring.

It is rated 15W, and this is the AC 200V to 240V version for Saudi mains power. The light is cool white, at about 5500 to 7000K, with a listed output of about 500 to 999 lumens, bright enough for an entrance, a garage or a side passage. The wall switch for the fitting stays on, and the sensor then decides when the bulb lights. The listing photos advise keeping the sensor away from strong light, such as another lamp shining on it, so it reads the daylight correctly.

It suits porch and gate lights, garden lanterns, garages, stairwells, parking areas and corridors that should stay lit at night. An open fitting or one with a clear shade works well, since a closed, dark fitting may keep the sensor from reading the daylight. This item ships from abroad, with free tracked delivery to Saudi Arabia in about 10 to 18 days.
