This is a brilliant little light which I have attached to the top of my bathroom mirror as sometimes need better lighting when using makeup, particularly on dark mornings. This has so many different settings you can find the one right for you. I have it set to sensor to light up when entering the room so it helps throughout the night as well, Although the sensor only allows lighting when dark enough in the room, if you place you hand over the sensor it will light up so you can get the illumination you need even in daylight.
