Over the next years, the National Gallery, London, will install indoor LED lighting throughout its galleries, which will significantly reduce carbon emissions & improve the quality of light. The Gallery claims that it will be the first institution in the world to make use of LED lights together with a method that automatically adjusts outside roof-light blinds according to the amount & angle of sunlight. This ensures that only diffused light is present in the galleries through UV-filtered roof-light glazing.
The new LED lighting method will slowly increase the natural light as needed, as against the elderly method that can be distracting to visitors by going on & off abruptly. This is feasible because LED lights can be dimmed with no change in color temperature, a major advantage compared to tungsten lamps.
Trials of the new lighting process have taken place in Room 62 of the Sainsbury Wing & in the Wilkins Building, where the new lighting process has been installed in Rooms 6, 7 & 8. More recently this has been extended to Rooms five & ten, which re-opened in April 2011. Because of these successful trials, the Gallery has decided to put in the lights in all galleries by & massive Wilkins Building & in the Sainsbury Wing. The new lighting won't only improve the public's enjoyment of the collection, it will also reduce the Gallery's emission of carbon dioxide by 400 tonnes each year.
This major initiative to replace all lighting in the galleries with energy-efficient, low-maintenance LED lights will reduce the Gallery's lighting energy consumption by 85%. The Gallery believes that the lifetime of the LED lamps is 25 times greater than that of the current tungsten lights, leading to a significant reduction in maintenance costs.
The National Gallery will install the lights in the Sainsbury Wing in a program from July 2011 to March 2012, & willcomplete the installation in the Wilkins Building by the spring of 2013. The use of the LED lights throughout the picture galleries will greatly contribute to the Gallery's overall carbon footprint reduction target of 43% that it is aiming to accomplish by 2014/15 through its Carbon Management Plan.
