Once Innovations Improved AC LED Efficacies

LED lighting technology developer Once Innovations has utilized its proprietary AC conditioning technology to turn out luminous flux of 1080 lumens at 11.8W and correlated color temperature of 2870 K.

50mm diameter AC LED modules are designed to connect to 120VAC, 60Hz mains without the need for additional electronics.

The company's SCD conditioning boosts system luminous efficacy significantly over simple resistive circuits. Documented testing using replicable industry standard protocol has shown system efficacies of 92 lumens per watt at 2850°K, an 85 CRI, and R9 value over 30. Modules incorporating AC conditioning technology are inherently dimmable with Power Factors at 0.98 and Total Harmonic Distortion (THD) under 21%.

ONCE believes these developments will make low THD levels and high PF commonplace in all LED based systems.
