Here are some Bluetooth controlled LED lanterns, called the Vela. They are the perfect interim device to illuminate any dark hallway when needed.

There's an accompanying app that will let you adjust its intensity using an on-screen slider, and give you a real time estimate of the boost in battery life after dimming its glow. It will let you set up timers for turning on and off at daily intervals as well.

There's also a flicker mode using a custom algorithm to flash the Vela's LEDs, and to recreate the ambience of a candle's flame. The whole thing was designed by Joe Van Faasen and his team at Twisthink. Check it out in the video below: [Twisthink]
