1. Super reliability, pass 4000V hi-pot test.
2. High lumen output, 310lm for white, equivalent to 40W incandescent.                                                                                                                                                                           
3. Use ceramic socket for better insulation and heat dissipation (instead of PC or ABS socket common on the market)
4. CNC machined aluminum housing, better thermal dissipation than die-cast aluminum housings.
5. Long lifespan over 50,000hrs.
