LED lights help museum save energy, preserve items

A spectacular collection of original oil paintings by emeritus Indiana University art professor Barry Gealt is on display in the IU Art Museum's Special Exhibitions Gallery, along with exhibits of baby carriers from China's minority groups and German expressionism. But look toward the ceiling instead of what's hanging on the walls, and it is evident that the paintings are illuminated by clean, cool, white lights, while the other exhibits bask in a warm, yellowish glow.
