Features: 1.Lamp inner arc tube with EBT's patented technology has advantages of longer life and more reliabiltiy 2.Few solder joints and solid structure make stronger anti-vibration and anti-shock ability, reducing early failure 3.Sold coold down ensures the best lumen maintenance and reduces early failure. Advantages: 1.High CRI, noticeable stablity and consistency of lamp-to-lamp color both in initial life and entire life. 2.High luminous efficiency and correction factor, samll difference in spetral tone. 3.High lumen maintenance ensures the lighting effects during theentire lighting period. 4.Longer life, shorter cold and hot start-up time. 5.Energy saving, high luminous efficiency, less thermal radiation, reducing running costs.
