The IFC/GEF Efficient Lighting Initiative (ELI)
2003 FAQ update

What is the purpose of the ELI technical specifications?

Inadequate information about the energy, economic and environmental benefits of efficient lighting, and a lack of credible sources of such information, can discourage purchases of energy-efficient lighting. In response, ELI developed and promotes voluntary technical specifications that address product efficiency and reliability. The ELI specifications are not part of any local or international law or regulation. However, manufacturers interested in participating in ELI must show that their products comply with the ELI specifications.
Products that meet the ELI specifications are allowed to bear the ELI “green leaf” logo. The ELI logo helps purchasers identify efficient, reliable products that perform according to manufacturer specifications. ELI also offered public education and marketing campaigns to inform consumers that the ELI logo is a sign of high quality and savings backed by credible performance data. Only lighting products that carry the ELI logo are eligible to participate in these campaigns and in the other market building and promotional activities that ELI conducts.

• Compact Fluorescent Lamps (CFLs)
• Indoor CFL Luminaires
• Outdoor Residential Luminaires
• Linear Fluorescent Systems
• Public Lighting
• Traffic Signals

Interested manufacturers can qualify their lighting products to carry the ELI logo by showing that they comply with the ELI technical specifications. Compliance with the ELI specifications is determined by review of product performance data submitted by accredited lighting laboratories.
