[Nhcoll-l] Lighting for large, modern, alcohol preserved specimens facility

[Anderson, Gretchen]

Hi Rob,

In this day and age LED's are the way to go.  They are more energy efficient and lower heat load.  You still need to be aware of the wavelength though and intensity.  Look for a good color balance,  Fluorescent bulbs generally have a high ultra violet component which is extremely damaging.  Incandescent bulbs are warmer in color and have a high heat load. You will have to check with your fire marshal about electrical outlets including the light.

When it comes to light always remember that all wavelengths cause damage.  This means that visible light UV and infra-red will all cause fading and permanent damage. Damage is from a combination intensity (brightness), wavelength and the length of exposure.  So, in general, you want to 1) eliminate UV & IR and limit the exposure as much as possible.

Hope this helps.
Gretchen

Hi Again,
Thanks for the quick responses!

I apologize that I didn't do a better job of stating my concern, which is for specimen damage from light reaching the specimens in their glass containers.

Is damage of this type a concern with LED or just fluorescent or incandescent light bulbs?

Best,

Rob

Hi Folks,
The University of Florida has funded and is planning the construction of a 29,000 gross sq. ft. (gsf) facility for the fluid-preserved collections at the Florida Museum of Natural History. (Hooray!).

Approximately 20,000 gsf will contain the compactorized shelving on which we will maintain, grow, and provide access to the millions of fishes, herp, and invertebrate specimens in our care (and a handful of mammals and birds).

My question for the group concerns lighting these spaces.

What we know: Lights will be overhead LED, motion activated by zone, and hopefully dimmable. We expect the shelving will be perforated.

The question: Being only generally aware of the potential threat to specimens from UV light systems, what if any safeguards are required for LED systems?

Best wishes,

Rob Robins
