Anatomy of the Label

As of March 2012, manufacturers will have the option of including lumen maintenance and warranty on the LED Lighting Facts label. The original five metrics, lumens, watts, efficacy, color rendering index and correlated color temperature, are still required. However, manufacturers can now choose to list one, both or neither of the lumen maintenance and warranty metrics. Therefore, there are four versions of the LED Lighting Facts label available for download:

1. Current and required label metrics
2. Current and required label metrics + Warranty
3. Current and required label metrics + LED Lumen Maintenance
4. Current and required label metrics + LED Lumen Maintenance + Warranty
