Plan to ban incandescant lamps

Having spent the last 15 years working as a lighting consultant and designer in London I can be pretty sure the domestic light bulb issue will not cross the theatre boarder. In the UK and most of the European Union laws are in place which affect all commercial buildings and although the tungsten lamp is not banned they work on a Lumen/Watt measurement. This means that you must achieve 50 lumens for every circuit watt of power you consume (L/W). An incandescent lamp only achieves around 20L/W. As a fluorescent can achieve over 70L/W you make saving in one place so you can use less efficient lamps in others. This way it still averages out at 50L/W across the site. In theatres the stage lighting is exempt as no other source can be dimmed so well. However, outside the auditorium the rules apply.
