I have been researching various forms of lighting currently being marketed to the museum field, and have found fiber-optics to be a viable (though initially somewhat expensive) option. They seem to be energy efficient, as one bulb can be used to send light to several different points. The up-front costs are greater than conventional lighting (or even LED), but the long-term benefits might make it worth it. There are several companies producing fiber-optics, the most intriguing one being NoUVIR Research: http://www.nouvir.com/ NoUVIR argues, as Marc Williams was saying, that it is not just UV that causes damage, but Infrared (IR) light as well. They have published the results of their extensive research on the subject, which is quite convincing to this lighting novice. They market a product that supposedly eliminates both UV and IR (invisible light energy that is absorbed by objects and thus causes damage), allowing only visible light through. I know I'm starting to sound like a NoUVIR salesman, so please note that I have not personally tried their product--I am relying only on the research they provide through their website and in the written literature they were gracious enough to send me. Such as: http://www.nouvir.com/pdfs/06MuseumLightingPDF.pdf As far as the expense of this system, I suppose it would even be possible to pursue grants to help offset the costs, since it is an effort to protect and properly care for artifacts. Anyone have any experience with NoUVIR in particular?

Global warming is a high priority topic these days and will become even more so in the future. Currently, I'm changing all of my light bulbs in my house to the new kind that are more energy efficient and last significantly longer. Changing the lighting in my museum is a different story. Has anyone begun to think about this and if so, is there literature available or does AAM have anything available to help us begin this changeover in our workplace? Ken Kenneth D.
