Decorative lanterns, vintage or new, are one of the easiest and most attractive ways to add lighting to an outdoor space. Cluster them on the dining table, group them at points around the edges of the space or line them up on a wall — the options are many and varied. You can use real wax candles or outdoor LED “candles.” The San Nicola Lantern shown here, $99, from Grandin Road, comes with three battery-operated flameless candles.
