好帖，带防水孔和不带防水孔判据不一样。
) q5 b) X; x3 m2 q另外问一下，IPX4测试后，灯泡上面有水珠，带电部件没有水珠，符合要求吗？

实际使用中，随着时间的增加，灯泡上的水珠越来越多，多到一定程度它会沿着灯泡渗入到灯座里面呀，那样不是很危险？

IPX4测试后，灯泡上面有水珠，不符合要求。已经和LCIE确认过了。

有些灯泡发热淋到水就会爆。

: ]# o* c# G6 k. T- F3 [$ @1 g请查看标准IEC60598-1：2008第9章节，关于淋水测试的相关要求，明确规定灯泡上不得有水迹。由于标准很长时间没有查看，我的描述有误，特此更正说明：灯泡上有水迹否，与灯具的具体安装位置相关的，如柱灯。针对此问题，好早前与某知名机构经理交谈过，标准没有明确规定灯泡上不得有水迹，但是实际操作时检测人员会考虑灯具安装位置的。
