E Energy-Rated Light Bulbs & Lamps

Products with an E indicate that they have been awarded an E energy rating by the EU energy label directive based on their energy efficiency index (EEI) relative to a standard incandescent light bulb. E rated non-directional lamps have a relative energy consumption of >95%. E rated directional lamps have a relative energy consumption of >175%. E rated light bulbs are typically halogens and incandescents.
