Simple: hang it wherever you want using the cord; pull once: the well-spread light comes on pull a second time: it goes out. Handy: it’s a practical and functional battery-operated bulb; runs on 3 AAA batteries (not included); so you can take the light where you don’t have outlets and light points. 40 hours of battery life (continuous use). Safe: the bulb does not get hot, it stays cool and the LED light immediately gives a pleasant, even, diffused and still strong (50 lumens) illumination. Sturdy: manufactured from very sturdy material, which makes the bulb resistant to impact; lanyard: 105 cm visible. Symple Stuff is, since 1906, an Italian company that cares about its products: be wary of imitations. Finish: Blue
