As a matter of fact, it looks a lot like a wine bottle cork. Pop the cork end off of the Bottlelight to expose the USB plug that’s used to charge the internal battery. When you need emergency lighting or even some ambient mood lighting without the risk of candle flames, you just twist the Bottlelight to turn on the “super bright LED” and place the Bottlelight into the neck of an empty wine (or similar) bottle. They can be used indoors or outdoors, where a candle might be extinguished by the wind. It’s available at SUCK UK for $15.00. A couple of these would have been nice to have on hand and charged up earlier this week when the winter storm hit here in Greensboro.
