SLNS-LED Museum Liberty Lantern

The Museum Liberty Lantern was originally 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.

Structural components are of high-strength cast aluminum and polycarbonate globe. The LEDs and electronic components are situated deep within the cast hood for maximum protection.  These attributes make the SLNS highly resistant to damage, weather, and the passage of time.

The Museum Liberty Lantern with LED provides several choices of the most current light engine technology to deliver high lumen output, exceptional light distribution, superior visual comfort, extended service life, and energy reduction.

Construction

All components and decorative base shall be high-strength ASTM 356.1 cast aluminum. Globe shall be polycarbonate with molded-in patterns on globe surface. The luminaire shall be comprised of a “floating” bullet-shaped globe supported by (4) decorative struts. A decorative cast ring shall connect with the support struts and receive the hood. Luminaire shall be welded, creating one integral housing with a removable hood. Luminaire shall create a weather-tight chamber for the LED components, driver(s) and internal optics.

LED components and driver(s) are securely affixed to the mechanical structures. A thermal management system dissipates heat to insure compliance with ratings of the LED components and driver(s).

Optical

SLNS has an injection-molded UV stabilized polycarbonate stippled globe that, together with internal optics, creates a symmetrical or asymmetrical light distribution to optimize performance, distribution, and visual comfort.

SLNS-120 has an injection-molded UV stabilized polycarbonate or high impact acrylic prismatic globe that, together with internal optics, creates a symmetrical or asymmetrical light distribution.

Additional configurations available upon request.

Electrical

Meets UL 1598 for Safety. Luminaire shall utilize voltage sensing 120-277V driver, suitably rated for the specified LED light engine(s).  Luminaires shall be prewired and factory tested.

Surge Protection

Surge current rating of 20 kA using standard 8/20 µSec wave.  Protected line-neutral, line-ground, and neutral-ground in accordance with ANSI/IEEE 62.41, Category C3.

Finish

To insure product durability, all exposed metallic surfaces shall be finished with a high performance coating consisting of high gloss Super Durable polyester powder coat paint to be applied utilizing a multi stage process that includes phosphate pretreatment, electrostatic powder application, and convection curing.  Paint shall be weather, corrosion, abrasion, and UV resistant in compliance with the American Architectural Manufacturers Association’s specification AAMA 2604- 05.  Color to be specified.

Mounting

Mounts to a Ø3” by 3” tall tenon. Three (3) 3/8”-16 UNC stainless steel allen head cup point set screws secure luminaire to post top tenon. All mounting hardware shall be stainless steel.
