The Snapshot Reports are an analysis of the dataset underlying the U.S. Department of Energy's (DOE) LED Lighting Facts Product List. These reports are designed to help retailers, distributors, designers, utilities, energy efficiency program sponsors, and other industry stakeholders understand the current state of the LED lighting market and its trajectory.
Luminaires make up more than 70% of all products currently listed by LED Lighting Facts. This report, based on data through the first quarter of 2014, focuses on five types of luminaires intended for use indoors: 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). Efficacy performance was divided into two groups: troffers/industrial/ linear and downlight/track. Factors contributing to the divide may include form factor, intended use, or qualification thresholds.
A review of the products listed with LED Lighting Facts as of April 1, 2014 reveals that in many cases, the performance of LED luminaires is similar to the products they are replacing, in terms of lumen output and color quality. For example, the LED troffers are generally comparable to two-lamp fluorescent troffers. Another interesting result of this analysis is that the power factor for the luminaires is generally excellent. Overall, the performance of LED luminaires offers a compelling option for specifiers of interior lighting. Additional highlights from this report include:
- For the 11th consecutive quarter, the mean efficacy of newly listed products has increased, and is now at 86 lm/W.
- In all five categories, over 70% of the products meet relevant efficacy qualification criteria from energy efficiency programs.
- Although performance was highly variable, the lumen output of LED luminaires was often similar to that of typical conventional luminaires of the same type (where applicable). That is, at least 50% of the products had lumen output within a range considered typical for a conventionally lamped luminaire.
- The dataset shows little correlation between color quality and luminaire efficacy.
