SBCA3-LED Bishops Crook-A3

A perennial favorite, the Bishops Crook luminaire remains as a popular choice for street, park, and plaza lighting. The downward facing refractive globe delivers an uninterrupted hemisphere of directed light while also delivering the benefits associated with solid state lighting technology.  Most notably, users will realize a reduction in energy consumption, maintenance, downtime, and various costs associated with today’s sustainable initiatives.

     

At the heart of the Bishops Crook LED luminaire is Sentry’s directional optics, which work in tandem with the refractive globe to optimize light distribution while providing comfortable, pleasing illumination.  As specified, several globe/lens options are available to provide the desired aesthetics and performance.

    

The Bishops Crook series is highly resistant to damage, weather and the passage of time. With its high-strength cast aluminum and heavy gauge spun aluminum structural elements, it is able to withstand the rigors associated with roadway and area lighting.

Construction

All components are made from high-strength ASTM 356.1 cast aluminum and heavy gauge spun aluminum. Top casting shall have a cast aluminum captive hinge and (1) solid catch with thumb triggered secondary lock securing the liberty bell spinning which allows quick and easy access to the luminaire's interior.

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

Borosilicate glass, injection-molded polycarbonate or acrylic refractive globe in combination with LED module and internal reflectors and/or refractors to optimize performance, distribution, and visual comfort.

Available in Type III, or Type II with Backlight Reduction.  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 engines.  Luminaire 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 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 2” NPS nipple using a 2” NPS coupling in top casting of luminaire. One (1) 3/8”-16 UNC stainless steel allen head cup point set screw stops the luminaire from unwanted movement on the 2" NPS nipple.
