luminous tube adopt purity rare earths tricolors long life,the average life are more than 8000 hours energy saving 1/5,compared with nomal lamps adopting german advanced ballast technology, realiablity of energy saving useing German Bayer PC Engineering flame retardant materials low THD,without Interference ,three THD small than 81 adopting three color base rare ,ensure the brightness Current peaks small than 1.7 ,prolong the using life of luminous tube
