April 24 (Reuters) - The world's biggest lighting maker Signify LIGHT.AS reported a 12% drop in its quarterly nominal sales to 1.27 billion euros ($1.48 billion) on Friday, dragged by currency effects related to the depreciation of the U.S. dollar.
The Dutch company confirmed its full-year guidance for a core profit margin of between 7.5% and 8%, but declined to provide a sales forecast.
