About this file

This document is a Supplier Questions and Park Responses file for the Minidoka National Historic Site Visitor Center (MIIN) Electrical project. The park provides detailed responses to three supplier questions regarding museum lighting requirements. The key details include the need for museum-grade lighting fixtures with adjustable lumen output and aim to accommodate fragile display items such as books, photographs, uniforms, artwork, and historical artifacts. The existing lighting system by Zumtobel (Slotlight LED in "Titan" color) is now obsolete, and the park seeks a knowledgeable lighting company to help determine appropriate lighting that balances visitor experience with preservation of sensitive museum objects.

The document emphasizes the critical requirement of finding lighting solutions that are bright enough for visitors to fully appreciate exhibits while simultaneously preventing damage to historically significant materials. The park desires flexible lighting fixtures that can adapt to changing exhibit layouts and protect delicate items like 1940s photographs, military uniforms, leather and plastic luggage, and various rotating exhibit materials. The lighting specifications should consider lumen intensity in the 50-300 range, with an emphasis on adjustability and preservation-friendly illumination.

Supplier Questions and Park Responses MIIN VC Electrical

1. Can you give me some input on what we are lighting? Will it be parchments, pictures, ceramic etc.

Park Response: The Minidoka National Historic Site Visitor Center (MIIN) houses an assortment of modern interactive laminated MDF displays and historic items mostly housed in protective museum grade display cases. The items sensitive to light include books, paper documents, original photographs from the 1940’s, cloth (military uniforms, hats, clothing, muslin cloth), leather and plastic luggage, artworks such as screen-printed monographs, a wood and cloth doll made at Minidoka during incarceration, Greasewood sculptures created from local fauna. Rotating exhibits could feature a variety of materials as well such as glass marbles, tin toys, doll fragments, ceramic and porcelain plates, etc. So, in summary, just about every imaginable fragile material could be found on display at the

MIIN Visitor Center.

2. Do you know what lux are you going to want 50-300 or lumens?

Park Response: We would like fixtures that have adjustable lumen output and adjustable

‘aim’ which would allow more flexibility in the future as museum exhibits and layouts change. An important outcome of this project is to improve lighting so that visitors can fully enjoy the MIIN VC. It’s too dark right now. Overall, the objective here is to find a balance between a well-lit museum space and lighting intensity that does not accelerate the disintegration of the museum objects. We are seeking a knowledgeable lighting company to help make the lumen decision. So, in summary, bright but not damaging bright lumens

3. I need a little more information on these types of fixtures. Do you have part numbers and any info on the lighting outside of the 1 picture?

Park Response: From 2018 documents: Existing system is made by Zumtobel. Slotlight

LED. Color spec is “Titan”. I’ve been informed that the system is obsolete.
