I don't know exactly what the energy consumption efficiency rating is, but if there is a 100w grade 1 and a 50w grade 5, which of the two products uses less electricity?

pu2. The energy consumption efficiency rating is the difference between how little and how much you used in the same product line. If it's the first grade of 100w, other products in the same product line use 200w and 300w, so it's the first grade
