The Philips Aurelle Candles burns with a realistic flame using LED. The lights are rechargeable and gives you 10 hours of flickering candlelight per charge.
The frosted glass vase surrounding the LED is wind-proof and water-resistant, making it a perfect light source for your garden. Prices from $15.

The Sharper Image has been selling something similar (if not identical) for years. (They DO look kinda cool in action.)
