Features: 1.Lamp inner arc tube with EBT's dual-arc tube patented technology has advantages of longer life and more reliability 2.Few solder joints and solid structure make stonger antivibration and anti-shock ability, reducign early failure 3.Solid cool down ensures the best lumen maintenance and reduces early failure. Advantages 1.High CRI, noticeable stability and consistency of lamp-to-lamp color both in initial life and entire lfie. 2.High luminous efficiency and correction factor, samll differnece in spectral tone. 3.High lumen maintenance ensures the lighting effects during the entire lighting period. 4.Dual Arc design ensures longer life, shorter cool and hot restrike time. 5.Energy saving, high luminous efficiency, less thermal radiation, rudcing running costs Application: 1.Road lighting based on commercial power 2.Road lighting based on solar power.
