(Reuters) - Signify, the world's biggest maker of lights, reported second-quarter adjusted core profit on Friday that missed expectations, hit by a decline in the conventional lighting sector and persisting market softness in China.

Adjusted earnings before interest, taxes and amortisation (EBITA) dropped 13.2% on the year to 118 million euros ($128.11 million), falling short of the 138 million analysts expected on average in a company-compiled consensus.
