After five years of restoration, modernization and seismic retrofitting, the historic Rotunda building of the Los Angeles County Natural History Museum in July 2010 reopened with a new face and a whole new set of lighting—decorative LED bulbs supplied by Torrance, California-based LEDtronics, Inc.

Renovation of the 97-year-old Beaux Arts-inspired building was part of a multi-phase, $107-million project that included the modernization of the electrical system to support multimedia presentations and events, improve climate control and enhance exhibition lighting in an energy-efficient manner. Modernizing of the lighting system involved a retrofit from incandescent light fixtures with custom-manufactured LED systems without compromising the historical integrity of the original fixtures, notably in the Rotunda.
