必须得说,LED灯在节能省电方面的优势确实非常明显。如果每天开灯4小时,以广州居民生活用电0.61元/度计算,点一年白炽灯电费为35.6元,LED球泡灯只有4.4元。这也是为什么,LED灯的发展一直有一个叫《中国逐步淘汰白炽灯路线图》的红头文件“保驾护航”。不过,对消费者而言其实还有许多疑问:安全性是否过关,宣称的使用寿命是不是真的,哪款灯泡更适合家庭使用? Must say, LED lights in the energy saving is indeed very obvious advantages. If you turn on the lights for 4 hours everyday, the electricity consumption of Guangzhou residents will be 0.61 yuan / kWh, the incandescent electricity cost will be 35.6 yuan a year, and the LED bulb only costs 4.4 yuan. This is why, the development of LED lights has always had a red head file called “Escorting China” to phase out the incandescent lamp roadmap. However, consumers in fact, there are many questions: whether the security clearance, the declared service life is not true, which bulb is more suitable for home use?
