DOE Publishes CALiPER Snapshot Report on Indoor LED Luminaires
June 5, 2014
The U.S. Department of Energy's CALiPER program has released a Snapshot Report on indoor LED luminaires, which utilizes the LED Lighting Facts® program's extensive product database to help industry stakeholders understand the current state and trajectory of the market for that class of products.
Based on data through the first quarter of 2014, the report focuses on five types of indoor luminaires: downlights, industrial ambient luminaires (e.g., high-bay and low-bay), track heads, troffers (e.g., 2×4, 2×2, 1×4), and linear fixtures (e.g., linear pendants, strip lights). Together, these five product types represent the bulk of all indoor luminaires listed by LED Lighting Facts, and about one-third of the total products listed.
Among the report's highlights:
- For the 11th consecutive quarter, the mean efficacy of newly listed indoor LED luminaires has increased, and is now at 86 lm/W.
- In all five categories of indoor LED luminaires, over 70% of the products meet relevant efficacy qualification criteria from energy efficiency programs.
- Although performance was highly variable, the lumen output of indoor LED luminaires was often similar to that of typical conventional luminaires of the same type (where applicable). That is, at least 50% of products had lumen output within a range considered typical for a conventionally lamped luminaire.
- Efficacy performance was divided into two groups: troffers/industrial/linear and downlight/track. Factors contributing to the divide may include form factor, intended use, and qualification thresholds.
- The dataset shows little correlation between color quality and luminaire efficacy.
