Tech Ceramic translucent tubes are made from 99.99% polycrystalline alumina and sintered at high temperature (1800°C-1900°C) under reducing condition. Translucent envelopes or tubes are used for high pressure sodium lamps. It has stable chemical property, high mechanical strength and exhibits excellent electrical and thermal characteristics.
Tech Ceramic provides different type of arc tubes for high pressure sodium lamps (HPS lamp) such as niobium tube series and niobium wire series.
High pressure sodium lamps (HPS lamp) are in high demand as an energy efficient light source mostly used for street lighting as well as industrial use.
