光谱十分接近于太阳光谱， 从而使灯的发光效率及显色性大为提高。
Spectrum very close to the solar spectrum, so that the light-emitting efficiency and light color of greatly improved.
虽然白炽灯的发光效率极限是每瓦52流明，然而这钨丝在其熔点的理论亮度。
While the upper limit for incandescent lamps is 52 lumens per watt, that is the theoretical luminosity of tungsten at its melting point.
并且其发光效率比普通荧光灯提高了30%，约为白炽灯的5倍。
And its luminous efficiency than ordinary fluorescent lamps increased by 30%, about 5 times the incandescent lamp.
