I know what the efficiency is but what's the difference between gold, silver and bronze?
EDIT: and platinum
They are different minimum efficiency thresholds given by some standards body, bronze is something like 80%, silver 84%, etc... I don't really know the exact values, since it is pretty useless. The ratings are given at a temperature lower than normal operating temperature, and efficiency differs depending on voltage (our 220v will give better efficiency vs US 110v), so it is better to check efficiency values of reviews.
