LeDiamond Omni-Directional LED Filament Passed LM80 Test

LeDiamond (LED package manufacturer) announced that its Tesla filament has successfully completed the requirements of the rigorous 6000 hour lumen maintenance test (LM-80) by Bay Area Compliance Laboratories (BACL). It’s a big breakthrough for LeDiamond on its LED filament development.

The Tesla filament series achieves an efficiency of 180lm/W at 5700K(CRI 70) or 160lm/W at 2700K(CRI 80). Using transparent ceramics as substrates results in good thermal stability and high lumen maintenance. Tesla series are mainly used in candle lamps and bulbs.
