New and Underutilized Technology: Exterior LED/Solid State Lighting

The following information outlines key deployment considerations for exterior LED/solid state lighting within the Federal sector. This information spans:

• Benefits
• Application
• Key Factors for Deployment
• Ranking Criteria
• Resources

Benefits

LED lighting economics can work in high electric cost areas with high hours of use. Pricing continually decreases for LED lighting. This technology provides quality, white, even lighting with good color rendition. Greater cost savings can be achieved when combined with bi-level motion sensors to reduce light levels in parking areas, garages, and walkways.

Application

Exterior LED/solid state lighting is applicable in areas where security and visual performance are critical, including street lighting, parking lots, garages, walkways, building exteriors, and landscape areas.

Key Factors for Deployment

LEDs have no re-strike issues and can be effectively switched with bi-level motion sensor controls.

Ranking Criteria

Federal energy savings, cost-effectiveness, and probability of success are ranked 0-5 with 0 representing the lowest ranking and 5 representing the highest ranking. The weighted score is ranked 0-100 with 0 representing the lowest ranking and 100 representing the highest ranking.
