You can’t touch it, taste it, hear it or smell it, but without it we wouldn’t be able to see. Light; it is one of the elements that causes the most damage to a museum’s Collection. As a museum we are responsible for caring for the items in our Collection, displaying them for the public and making sure that they are protected from potential irreparable damage…and to do this we need your help!
Light: the facts.
- The speed of light is 299 792 458 m/s or 670,616,629 mph, fast enough that if you travelled at the speed of light you could go around the World 7.5 times in 1 second.
- Without light there would be no life on Earth.
- Light is electromagnetic radiation and our eyes can only see a certain portion of light, this is called visible light.
Both visible light and ultra violet light, which the human eye can’t see, cause damage to organic items within our Collection. Visible light causes objects to fade. UV light does this too at a much faster rate whilst also degrading the item on a molecular level.
We have a collection of tapestries, like this one, that needs our protection
We can stop this by limiting the amount of light that gets to the objects. The best way to do this is to keep them in a dark box so no light could get to them. Unfortunately this would make us a very boring museum as there would be nothing for our visitors to see. So we need to use blinds to block light hitting objects when we are not open to visitors, put UV filters on our windows to eliminate UV light getting through and to replace our existing light bulbs with LED bulbs that don’t emit UV light.
What will this cost?
1 LED light bulb = £3.50
1 window pane UV filter = £4.50
1 window UV filter = £54
1 window blind = £95
And how many do we need…?
76 light bulbs
162 window pane filters
7 window blinds
