Energy Gateway Project at the Field Museum of Natural History in Chicago, Illinois

The U.S. Department of Energy (DOE) has published a report from a demonstration conducted at the Field Museum of Natural History in Chicago, Illinois, to evaluate the feasibility of replacing halogen lamps with LED lamps. It forms part of the DOE’s GATEWAY project series which demonstrate real world experience of LEDs.

This GATEWAY study, carried out in late 2009, compares lighting performance, economic performance, and energy  consumption of halogen and LED accent lighting solutions.  Xicato Spot Modules in LX2024series luminaires from Lighting Services Inc were used in the study, carried out as a collaboration  between the The Field Museum of Chicago and the United States DoE represented by Pacific Northwest National Laboratory (PNNL) in late 2009.

In this project, 32 halogen track luminaires used to light an enclosed gallery exhibit were replaced with an LED system using 26 track fixtures. Key findings include:

The LED system resulted in 63 percent energy savings compared to the halogen system and produced comparable illuminance on the lighted artifacts.

The simple payback for the overall LED system compared to the halogen system was roughly 3.3 years and was further reduced to only 2.4 years when considering the lower heat output from the LED luminaires and associated HVAC energy savings. The payback calculation considers the longer life of LEDs,  lower maintenance costs and that fewer LED luminaires are needed to generate an equivalent amount of light compared to the halogen fixtures. 

Because the LED luminaires used do not emit energy in the infrared or ultraviolet regions of the electromagnetic spectrum, they are expected to be less detrimental to some museum artifacts.
