Eureka announces that its acoustic luminaires are now available in 30 colors. Spaces can feature a neutral palette to blend or soften an aesthetic or have dynamic splashes of color across a ceiling or wall. Sound absorbing acoustic panels are comprised of high-density PET (polyethylene/polyester) felt and of at least 40 percent recycled content. When sound encounters the felt fibers, the fibers move slightly to absorb a portion of the sound.
