SON 1.Patent powder metallurgy electrode improves start performance greatly. Even there is high pressure xenon gas in the arc tube, it also can be started easily without metal wire on the arc tube. 2.Plentiful eradiating material in the electrode keeps better start performance in the evening and stability of lamp voltage, which extends service life greatly. 3.Optimized material scale makes lumen decrease much lower and improves energy-saving potential. 4. High lumen output, 20%--25% higher than common sodium lamp, which can save more energy. 5.Short restart time. 6.Special arc tube process keeps high lumen output.
