PARIS, Jan 30 (Reuters) - French shops and office buildings will have to turn off their lights at night to save energy and reduce light pollution, the French environment ministry said on Wednesday.
From July 1, all non-residential buildings will have to switch off interior lights one hour after the last worker leaves the premises. All exterior and shop window lighting will have to be turned off by 1 am.
Local authorities will be able to allow exceptions for Christmas lighting and other local events.
