New and Underutilized Technology: Bi-level Garage/Parking Lot/Pedestrian Lighting
The following information outlines key deployment considerations for bi-level garage/parking lot/pedestrian lighting within the Federal sector. This information spans:
Benefits
Bi-level LED lighting uses fluorescent and LED lighting sources with bi-level motion sensors to reduce lighting levels when the parking area is not in use.
Application
Bi-level LED lighting is appropriate for garage, parking lot, and pedestrian areas. It can also be applied to pathway lighting where appropriate.
Key Factors for Deployment
Evaluate specific lighting and environmental requirements before deployment.
