The Integral LED Auto Light Sensor light bulb is a dusk til dawn LED GLS light bulb from Integral LED that employs 2x dual light receptive sensors to recognise the level of daylight and subsequently turn itself on at dusk and off at dawn accordingly, saving money and energy.This light bulb is ideal for external porches, walkways, paths and patios but needs to be enclosed in a suitable weatherproof fitting if used outdoors. The light bulb is fitted with a common place ES-E27 Edison screw (27mm) base/cap.It emits a warm white light at 470 lumens - equivalent to an old 40W incandescent light bulb. With its auto on/off function, this represents an efficient, retrofit alternative to existing lightbulbs.
