白光灯
The end result looks so different from what we've come to expect of bulbs that every AmbientLED package carries a large sticker: WHITE LIGHT WHEN LIT.───这一结果与我们从ambientled包装上的标语得到的理解大相庭径，上面写着：点亮白光。
The human eye tends to adjust to local lighting conditions, so an object that looks white in a dimly lit room may in fact be less bright than an object that looks grey in full daylight.───人眼倾向于以适应本地的照明条件，所以，一个物体在昏暗的房间里看起来是白色的，并不比在日光下灰色的物体亮。
white light flashed, lit the sky in silver.───白光闪起，夜空亮起银辉。
