A Directional night light with Photocell Key West uses 1W white LED and it is bivolt. Just plug it into a socket and when the environment is dark, it lights up automatically.
The light is weak, But enough to get around in the dark without bumping into furniture, stops, stumble on stairs, etc. And consumption is very low.
The acquisition was made to illuminate the place where my dog when nobody's home, so he doesn't get in total darkness. The cost was R$ 42,90, in a physical store of Multicoisas.
