使用 150 颗 LED 的灯泡仅耗电 9W

由 Bin Chen 于 2 years 之前发表

LED 灯泡省电、耐用，但是贵的要死。该怎么说它们才好呢？以这颗使用 150 颗 LED 的大灯泡为例，它可以输出 308 流明的亮度 -- 约和 70W 左右的白热灯泡相当 -- 但仅耗电 9.2W ，约省下了 87% 的电力。听起来不错吧？但是要大约525 人民币一颗的价格？坑人啊！以0.5元一度电来算，大约要 1000 度电，也就是要能省下 1,000,000 瓦/小时的使用量才能赚回来。这可是连续开着它不关 16,600 个小时的量啊！

不过幸好，LED 灯泡还另一大法宝：耐久。据说有 LED 灯泡号称自已可以使用 100,000 个小时的（快 12 年）。如果真能用这么久的话，省个 16,600 小时下来不在话下啦！可是，真的能用这么久？

用来做城市照明比较好，虽然采购奋勇没省下，但可以减少维护成本，呵呵！
