LED leader Cree goes after office, institutional settings with larger fixture

The U.S. Federal Reserve Building in Washington, D.C., is one of the first offices to use a new 24-inch square LED luminaire from Cree Lighting called the LR24. So far, about 1,000 of the new product have been installed in pilot accounts.

These are the sorts of lights that you'd see in many "institutional" settings, such as offices, schools, hospitals or retail environments. Cree says the LR24 can deliver high lighting levels at 0.5 watts to 0.75 watts per square foot. The company also touts the LR24's color rendering capabilities, which score 92 on the color rendering index (CRI) compared with 70 to 89 for linear fluorescent light bulbs. The technology is designed to last for up to 50,000 hours.
