Stadium lights on until so late

Letter from Ishwar Mahtani, Today Online 2 Apr 08;

Recently, the lights at the Na-tional Stadium seemed to have been kept on until very late at night and on one occasion, the stadium remained lit until 2am.

The lights are so bright that they shine into my house even though I live about 5km away. Not only is this disturbing to me, it wastes energy too.
