How to distinguish the true and false of lamps and lanterns?
我们可以从下面这几个方面来看以下
材质方面
一般的白炽灯的灯泡口都是白铁的容易生锈，质量较好的灯具一般是用的铝合金的，不易生锈
灯丝方面
好一点的灯具，都是双钨丝，差的事单的
亮度方面
对于灯管，如果好灯管因为是机器一次性涂粉，通电后亮度是均匀的，而差的事人工涂粉，亮度不均匀
价格方面
在购买灯具时不要只图个便宜，因为质量和价格肯定是成正比的
认证方面
要看其右无3C认证资格，并对其内容进行审核
新旧方面
新颖的产品未必技术成熟，购买时不要只选最新出的，而忽略老型号的产品 Leo
