[Nhcoll-l] Inquiry about installing Germicidal Lighting device (405nm) in museum space

[Abraczinskas, Laura]

Hello,
Does anyone have information about the use of germicidal lighting in museums and effects on collections?  I learned today that a device known as "Indigo-Clean" is scheduled to be installed in the Museum's classroom.  This is a space where specimens (mainly birds, mammals, and vertebrate fossils) are displayed and placed on tables for students to examine during weekly lab sessions.   The lights are described as LED Luminaires.

A university engineer provided the following information and links.
" Indigo-Clean operates at 405nm which is just outside of UV range.  UV is 100 to 400nm.  Please use the link for detailed information on this technology.  https://www.nature.com/articles/s41598-021-97797-0

I'd appreciate any advice or information!
Thanks and best,
Laura
