Fiberglass base：This kind of G4 bulb based fiberglass PCB has high stability in isolation performance, ultra flatness without any pits. Also, it well-performed on heat-isolation, environmental protection and fire-retardant.
Pin-out：After antioxidant treatment it will well protect the pin-out interface and make it won’t be easy rusted.
High temperature tin with lead free：Fast speed in heat dissipation and won’t be easy to take pseudo soldering. Good in gloss and no harness to environment.
High-quality SMD chips take wide-angle of lightings. The CT has great stability which won’t drift along with the temperature increasing.
Working Temperature：Between-30℃～+50℃，Relative humidity less than 98%.
Storage Temperature：Between-30℃～+60℃，Relative humidity less than 85% 
Electric shock rating：Ⅲ
