A laboratory experiment was conducted to investigate the usefulness of colored LEDs in retail display window applications. Human subjects viewed two side-by-side, identical mock-up display windows, and rated their preference. Subjects showed strong preference for the colored background, compared to the white background. In general, subjects disliked the modulated intensity background. Furthermore, the use of colored light (static red and blue) on the background allowed the accent light to be decreased without sacrificing visual appeal, ability to capture attention, and ability to see displayed objects clearly. It appears from this initial laboratory study that the amount of accent light can be reduced significantly, which could provide energy savings. We believe a field study would be greatly beneficial for further confirming these results and for quantifying the total energy savings in an actual store.
