LeDiamond Omni-Directional LED Filament Modules Successfully Passed LM80 Test – Introduces New Versions

Features:
•    Omni-directional light source
•    No heat sink required, reduces the heat dissipation cost of lamps
•    Using a non-isolated circuit resolves safety problems
•    The highest lm/W compared to a traditional LED package

The Tesla filament series achieves an efficiency of 180 lm/W at 5700 K (CRI 70) or 160 lm/W at 2700 K (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.

Tesla 2903 filament(2700 K) had been through a 6,000 hours of 50 mA experiment from BACL. The test report (see table below) shows the specifications of the data is much higher than indoor residential data by 91.8%, outdoor and commercial data by 94.1%.

The LM80 report from BACL also covers LeDiamond Tesla series 1505 and 0705. The verified report by international organization may gain more confidents from lighting manufactures by using LeDiamond products .
