Hello,
Thank you for your enquiry.
Currently the labels for bulbs range from A++ to E, however most products fall into the highest ratings, making it difficult to determine which products are more energy efficient than others. To make this clearer, the energy ratings are moving to an A to G scale, with A being the highest rating and G being the lowest. Hope that helps.
Thank you for using Q&A.
