1.The diameter is 58cm and the length is 1800cm.
2,High efficient temperature raised:Adopting the advanced coating technology,light converted into heat is 10% higher than the normal vacuum tube.
3.Endure the coldest temperature:Adopting the advanced vacuum technology,the vacuum degree can ammount 5*10-4 Pa convection heat emission,at the smae time the infrared reflector layer reduces the radiant emission,enable the tubes can work well in the coldest temperature area.
4.Function stable:It has long longevity;Going through 36 working procedures ensure the coating stabilization and withstand attenuation.
