To whom it may concern; LED technology is currently advancing at such a fast rate it is not always possible to keep printed documentation up to date. When first launched the Philips MASTER LED 7w GU10 lamp had an efficacy of 38 lm/w. This is the complete efficacy including optical and gear losses. The basic source of light has a much higher efficacy. Current production of this product is in the range of 45-48 lm/w so we are comfortable in claiming that the 45lm/w figure complies with the domestic requirements of Part L 2010. Yours faithfully,
Mike Simpson Technical Director
