Random anecdote while reading this: I used candle light few years ago after being forced off grid for a few hours at night. It was marvelous. If it wasn't for fire hazard I'd use it every night.
My kids and I love LED candles. They look like 3-inch diameter cylindrical candles, complete with a wax exterior (which is, I admit, really frustrating at times), and have an LED inside that provides a flickering light. As a bonus, the batteries seem to last nearly forever since it's basically one LED and a small circuit.
