Advantages of Tube in Tube K
1)more energy saving than T8,60% saved, higher illumination than T5,30% higher.
2)the special design circuit contributes to the reduce of reactive power,and improves the light efficiency
3)a special processing nano reflecting film improves the intensity of illumination while keeps the light soft,protects our eyes.
4)pure tri-phosphor fluorescent powder whose light fade is much lower than halogen powder and mixed powder.
5)the use of PPD fire-proof plastic material and explosion-proof glass tube guarantees the safety while using tube in tube.
6)easy installation,you can replace the ballast yourself.
