The IEA 4E SSL Annex is active in two key areas that relate to product performance:
Product Performance Tiers
Are you 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 efficacy, colour, lifetime and power quality for the most common SSL applications. These product performance tiers are a limited number of potential performance levels, agreed upon by IEA SSL Annex members, that could be utilised by government, non-profit and donor agencies when designing national programmes and market transformation initiatives. The objective of the tiers 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. In addition, they help minimise compliance costs with SSL programmes and policies by helping to establish harmonised requirements. Member countries are not obligated to use the tiers, and they are not international standards.
Energy Consumption of “Smart” Lighting
“Smart” lamps combine technology breakthroughs in wireless communications and light emitting diodes (LEDs). Often controlled by a smartphone app, these lamps can dim, change colour and shift to new scenes all by simply touching your phone. However, the lamps consume energy even when they are not in use. The standby functions drastically increase the lamp’s total energy use and the standby energy can easily be larger than the energy used for providing lighting. In order to better understand smart lighting features and their associated energy use, the IEA 4E SSL Annex is studing the energy performance of smart wireless lamps and luminaires.
