So I wanted to have the jack o' lanterns lit late at night without the hazard of candles or the power of flashlights. I found that the solar-powered outdoor lights worked well as long as the opening on top was wide enough. The sun recharges batteries which in turn power the orange LED to light the jack o' lanterns. It is about the same amount of light as a candle. It is cool to the touch so it is safe for kids. Once I'm done with the jack o' lanterns, the lights will be re-attached to their base and used as yard lights again.
