If the Royal Family were to vacate Buckingham Palace, what should the building (and the Mall) be used for - and how should they be lit? That is the subject of a lighting design competition run by Light 98, the commercial lighting exhibition held at the nec from 19-21 May. Two prizes of £1000 are on offer for the best entry from a lighting professional and a non-lighting professional. Entries should come from individuals or teams of a maximum of two. No corporate entries. An administration fee of £10 will cover the cost of returning boards. For full information fax ile Events on 01788 540145.
