Both series have been developed as light sources for general lighting applications (including light bulbs, base lights, down lights and ceiling lights), street lights and floodlights.

Utilizing gallium nitride-on-silicon (GaN-on-Si) process technology, the white LEDs realize low forward voltage (VF) and can contribute to lower power consumption and cost reductions in lighting applications.

Forward voltages realized are 2.85 V at 35 0mA (TL1L2-Series) and 5.76 V at 100 mA (TL3GB-Series). Luminous efficacy for the TL1L2-Series is 135 lm/W (5000 K, Ra70) at 1 W operation (If=350mA); for the TL3GB-Series it is 118 lm/W(5000 K, Ra80) at 0.6 W operation (If=100mA). Color variation of six colour temperatures is 2700 K to 6500 K.

Mass production of both series will start at the end of March 2014.
