Light cream - all the good taste but with less calories

While shopping in Europe, I discovered something I would like to be able to find at every food store in L.A. Pure, fresh whipping cream as well as sour cream with only 18 to 25 % milkfat. According to the California Milk Advisory Board there is a product called 'light whipping cream' with reduced milkfat, which makes me wonder why I can't find it in the refrigerated shelves of food markets. So far, I have only been able to get the 'heavy whipping cream' and regular sour cream. Dear dairy buyers, please get us some of the light stuff for all of us to indulge without the calorie overload. Many thanks!
