while preserving the natural night time setting appropriate for a national park

Interchangeability is achieved by defining interfaces for a variety of application-specific light engines. Zhaga standards cover the physical dimensions, as well as the photometric, electrical and thermal behavior of led linear high bay light engines.

Using Bridgelux LED arrays, Borden Lighting designed a unique indirect post top walkway luminaire. The Borden luminaire was developed to conform to "Dark Sky" lighting design concepts that effectively illuminate the pathway while preventing glare and light pollution.

The original lighting design plan called for the use of Metal Halide luminaires, not for LED lighting. Borden decided to use Bridgelux’s 1200 lumen ES led high bay light, not only for their greater energy efficiency, but also because the arrays offered much higher quality of light and long life in a small source size.

According to David Malman, project lighting designer from Architectural Lighting Design, "We used a warm 3000K white light to create a soft, welcoming appearance. I believe the combination of the dark sky luminaire design and the LED technology resulted in a beautiful addition to the landscape lighting while preserving the natural night time setting appropriate for a national park.
