Subject: LED lights in exhibition cases

LED lights in exhibition cases

From: Karen Potje <kpotje>
Date: Thursday, June 5, 2003
For the same CCA exhibition described above it has been suggested
that we use white LEDs on the *inside* of an exhibition case as the
light source for a display of documents.  UV light must be excluded
and the light level must be low (50 lux).  Is information about the
UV content of white LEDs available?  Is it possible to control the
light levels and ensure that they remain at a steady 50 lux  over
the course of a long (8 month) exhibition? Do LED lights start out
bright and then get dimmer over time?  The designer of the show
suggests that LEDs are cool--there will be no heat build up in the
completely enclosed exhibition case.  Is this the case?  Are LEDs
being used by other museums to light exhibition cases?
