Lighting type with high-efficiency
-LED:Semiconductor device that emits light by converting electric energy into light energy, applying voltage to semiconductor chip. High efficiency, low power consumption, long life, eco-friendly. -Ceramic metal:High efficiency, long life, high color rendering and high peak retention rate are maintained by sustaining the temperature higher than quartz glass used in conventional metal lamp inner tubes. -Electrodeless:It has the characteristic of high efficiency and high color rendering property, Especially, systems that are applied to facilities that are difficult to replace due to the lack of filament, unlike regular bulbs, and therefore have a life span of semi-permanent.
