DOE’s New CALiPER Snapshot Report on LED A Lamps

This report covers products listed as either A lamps or omnidirectional replacement lamps. The multitude of commercially available LED A lamps differ widely across a number of performance parameters — not just in their luminous intensity distribution, but in their energy efficiency, color quality, dimming, and compatibility with controls. Among the Snapshot’s key findings:

  • The mean efficacy of all LED A lamps is now at 69 lm/W.
  • 95 percent of those lamps meet the current ENERGY STAR efficacy criterion.
  • There’s still wide variation for individual products; e.g., those with lumen output equivalent to a 60W incandescent lamp range from less than 60 lm/W to nearly 90 lm/W.
  • Several LED A lamps are now available with lumen output equivalent to traditional 75W and 100W incandescent A lamps.
  • Approximately 91 percent have a CRI in the 80s, and a CCT of either 2700 K or 3000 K.
