DOE Publishes New CALiPER Snapshot on TLEDs

Among the key findings of the new Snapshot, which is based on DOE’s LED Lighting Facts® database:
• TLEDs now comprise more than 50% of all listed lamps, and more than 10% of all listed products.
• TLEDs offer the highest mean efficacy of any lamp type, and also offer the listed product with the highest efficacy (190 lm/W).
• In aggregate, TLED efficacy decreases by 3 lm/W for every 1000 K decrease in CCT.
• While the raw efficacy of TLEDs exceeds that of dedicated LED troffers, the reverse is true if TLED efficacy is adjusted to account for luminaire efficiency. In other words, dedicated LED troffers tend to exceed the efficacy of troffers fitted with TLEDs.
