KEYSTONE, S.D. (AP) - An Iowa-based company has donated a new lighting system to illuminate Mount Rushmore.

The new system donated by Musco Lighting consists of 39 fixtures with 20 light emitting diodes, or LEDs, per fixture and 10 fixtures with 84 LEDs for a total of over 1,600 directional LEDs.

The National Park Service says the new lights use fewer kilowatts per hour, which will result in an anticipated energy savings of 90 percent.

Park Superintendent Cheryl Schreier says the donation will result in an “enhanced visitor experience and protection of cultural resources.”

The sculpture is currently illuminated from sunset until approximately 8 p.m.
