LED lighting company Cree Inc. of Durham, N.C., has announced that LR24 recessed LED luminaires have been installed in the Smithsonian Institution’s National Air and Space Museum in Washington. Designed for the museum’s “Moving Beyond Earth” exhibit, the lights replace high-intensity-discharge work lights and provide the high lumen output and efficacy required to work in the gallery. They also weigh less than other fixtures, helping to reduce strain on the ceiling.
