One remark to UV filter glass which is the most expensive part of the lamp:

My lamp uses Hoya 325 filters, see the specs here (interesting link!):
http://www.hoyaoptics.com/color_filter/uv_transmitting.htm

Please not that UV filter does have a lifecycle: sooner or later they get solarisation effects and need to be replaced. I do not have specific information, for older glasses the rule of thumb was about 500 hrs lifetime, no idea about newer glasses.

Edit: here is a link to a solarisation test. Hoya perfomed best with -15% in 250 hrs.
