New and Underutilized Technology: Interior LED/Solid State Lighting
The following information outlines key deployment considerations for interior LED/solid state lighting within the Federal sector. This information spans:
Interior LED retrofits are currently viable for down lights, track lighting, sconces, and both line and low voltage task lighting. Replacements for incandescent A-lamps have also been improving rapidly. Replacements for fluorescent tube lighting may be viable for high-cost maintenance areas.
Interior LED/solid state lighting is a rapidly improving technology currently most applicable for down lights, track lights, task lighting, accenting, high ceiling, and high cost maintenance areas.
Key Factors for Deployment
Prior to deployment, evaluate sample LED products in their intended fixtures and applications to gauge appropriate fit – both physically within the fixture and lighting quality and aesthetic requirements.
Also evaluate test data to verify product performance is based on standardized photometric testing (e.g., IES Method LM-79-08) and not LED chip performance alone. Performance and life of the LED replacement lamps is highly dependent on their design and thermal management, which includes the fixture in with they are installed. The product should be covered by a warranty or return policy in case the lamp does not perform as claimed.
Examine ways to incorporate solid state lighting into lighting retrofit strategies, such as low ambient/task lighting.
