SLN Park Liberty Lantern

The inspiration for this unusually large fxture is 18th Century colonial America. Its contours and shapes derive from relics and illustrations of lighting from that period, when American design owed much to English and Continental sources. An internal borosilicate glass refractor delivers brilliant well-distributed light. Structural components are of high-strength cast aluminum and polycarbonate or acrylic globe.

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

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

Construction

All components including the hood and finial shall be high-strength ASTM 356.1 cast aluminum. The luminaire shall be comprised of a "floating" bullet shaped globe supported by (4) decorative struts. Hood shall hingge by means of a cast in hinge mating with (1) strut which allows for relamping. A decorative cast ring shall connect with the support struts and receive the hood and globe. Luminaire shall be welded creating one intergral housing with the hood. Luminaire shall cteate a weather tight chamber for the ballast assembly, lamp and internal optics.

Optical

Injection-molded UV stabilized polycarbonate or high impact acrylic clear globe.

Internal borosilicate glass refractor and aluminum reflector creates a symmetrical or asymmetrical distribution.

Available in a wide range of lamp choices and wattage ratings including High Intensity Discharge (HID), Incandescent, and Compact Fluorescent. Synchronized reflector system optimizes light output utilizing upper and lower Alzak® reflectors.

Electrical

Meets UL 1598 for Safety. Luminaire shall have porcelain socket rated for 600V with 4kV pulse and uses a nickel-plated screw shell with spring-loaded center contact and lamp grips. Luminaires shall be prewired and factory tested. The ballast shall be a high power factor, constant wattage autotransformer type. The power factor shall be at least 90%.

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 multistage 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 4” tall tenon. Six (6) 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.
