Conservation Lighting Design Solutions – A Light Study!
So following on from last time “Without adopting Conservation Lighting it’s a one way disappearing act! Part 1” you will have now carried out a light study of the space.
The first thing to realise is that the best possible solution for conservation lighting would be a space or gallery which has no daylight entering the space at all. This becomes your control of almost 0 lux level. There’s always going to be some light coming from fire exit signs etc.
So this is the perfect environment for conservation lighting where you can exactly control the lighting levels. Nevertheless this is not perfect for the visitors who want to view the objects. If you place people in really dark environments which is void of daylight their concentration & attention span drops dramatically. In certain situations this is the only option and the price you have to pay to see for example; ancient papyrus scrolls.
If it isn’t possible to black out the space then you have to first make sure that none of the light entering the space contains UV (ultra violet) light, which is the most chemically destructive. This is achieved by using UV filters and films on all windows doors and roof lights.

These fairly inexpensive filters and films can also be used to reduce dramatically the light levels, glare and solar gain (infrared radiation) entering the space.
Sometimes of course you will want to display sensitive objects alongside others which can tolerate a higher light level. This then comes down to the conservation lighting designer and his ability to focus fittings, stopping light spilling over into other areas where is not wanted.
Light management is the next task. How long will you allow an object to be exposed? The basic answer to this is as little as possible whilst making it still viable in the real world environment.
If daylight is allowed to enter the space then light management becomes much more difficult to monitor and log due to the ever changing external environment.
I cannot list here all possible conservation lighting design solutions to carry out light management. It very dependent on so many elements but I think you start to get the idea. You can always speak with one of our lighting designers and get and initial lighting consultation where all of these issues can be explained and a solution found.
