A typical 1 tbsp serving of light cream contains 0.4 grams of protein (2.96 g per 100 g), which makes it only a minor source of protein. That covers roughly 1% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Only about 6% of the calories in light cream come from protein, so it is more of an energy food than a protein food. It is worth eating for other reasons; the protein it adds to a day is incidental.
Among the 81 dairy foods in the database, light cream ranks 79th by protein per serving, and 782nd out of all 796 foods on the site. Set against sweet whey powder, another dairy food entry in the database, a serving carries about 0.6 g less protein (sweet whey powder has 1 g per 1 tbsp).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving above is measured by volume at 15 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
