SLNS Museum Liberty Lantern

This luminaire was designed to illuminate the grounds of the Philadelphia Art Museum. This graceful luminaire features fine detailing and a smaller globe for use in neo-classic architectural surroundings. This fixture is built with an internal borosilicate glass refractor. Structural components are of high-strength cast aluminum and polycarbonate globe.

Ballast assembly is situated deep within the cast hood for maximum protection. All these attributes make it highly resistant to damage, weather and the passage of time.

SLNS is designed to utilize a wide range of light sources, including High Intensity Discharge (HID), Compact Fluorescent, and others. These light source families provide the highest efficiency in lumen output, service life and energy use.
