Grand Canyon Visitor Center

Project Challenge

As interest and participation in the stargazing sessions grew, the park decided to upgrade their lighting control system to be able to turn off (or dim) pole lighting in the parking lots and dim walking path lighting systems to better accommodate the evening sessions.

The Solution

The lighting and control system includes 45 DALI-connected fixtures with three relay-controlled information panels and comprises 100% LED lighting controlled by two Equinox touchscreen control pads— one in the back room of the visitor center for easy access by park personnel and the other in the electrical room where the equipment is installed. While each fixture can be adjusted individually, the visitor center relies on automated operation through timed events. With preset lighting levels, the fixtures light pathways without interfering with stargazing activities.

Project Benefits

The lighting control system is durable and rated for outdoor use in all weather.
The system has great flexibility and is easy for rangers and park officials to use.
A single-wire daisy chain feeds through the fixtures, greatly minimizing wiring.
The control design helped meet the luminance criteria and energy requirements, establishing the facility as an International Dark-Sky Association (IDA) Compliant lighting installation.
