What a wonderful idea: lovely, glowing outdoor lanterns powered by the sun. Soji lanterns are made of translucent nylon and open like an accordion to a 10" diameter. Soji lanterns feature a solar cell, which collects sunlight all day. Then through the use of a single rechargeable AAA battery, they turn themselves on to cast a beautiful glow by night using an LED inside the lantern. Soji lanterns start at $22.46.
