The Dreamlight gently winks and blinks as you fall asleep to happy memories of glowing fireflies, warm summer nights and lazy vacation days. It works through solar power, containing 6 LED's which pulse on and off to create a light effect. Place in full sun during the day - the rechargeable battery soaks in the rays - and enjoy the illumination when darkness falls! Not recommended for outdoor use. http://www.urbanoutfitters.com/urban/catalog/productdetail.jsp?id=20593448&parentid=A_FURN_LIGHTING
