Product Performance

The IEA 4E SSL Annex is active in two main important areas that relate to product performance.

Product Performance Tiers

Striving for high quality, energy efficient SSL products in your market? The IEA-4E SSL Annex has prepared voluntary quality and performance tiers to address product attributes such as colour, lifetime, power, and efficacy for common SSL applications. These product performance tiers are a limited number of proposed performance levels, agreed upon by IEA SSL Annex members, that could be utilised by government, non-profit and donor agencies when designing programmes and policies. The objective is to provide a limited number of levels that can be utilised by programme designers to reduce costs of writing specifications and to facilitate economic advantages for industry/trade. Further, they help minimise compliance costs with SSL programmes and policies. Member countries are not obligated to use the tiers, and they are not international standards.
