此款灯可否用在"damp"环境
见附图请大伙帮忙看看此款吸顶灯能否用在“damp"环境，在认证上会不会有什么问题？大家有做过类似灯款吗？ 能具体地说：DAMP 环境吗？
一般的应没有问题。但如浴室等环境的要另外作考虑。 in a humidity cabinet containing air with a relative humidity maintained between 91 % and 95 %.
The temperature of the air at all places where samples can be located shall be maintained within
1 °C of any convenient value "t" between 20 °C and 30 °C.
After this treatment, the sample shall show no damage affecting compliance with the
requirements of this standard. 请问是申请UL吗？
如果是，按照UL1598，damp和Dry唯一不用的要求就是灯头的导电部分，必须是铜或含铜量80%以上的铜合金，或者不锈钢。总之不可以是铝。测试没有特别的要求。 符合IP65 仅从图片是不好说是否能做为“DAMP”环境使用的灯具的，需要提供参数才行的。不过，从产品形状来说，可以使用一些能满足“DAMP”要求的改进的。 引用第4楼SIMON段于2009-04-01 08:05发表的:
符合IP65
UL1598根本就不谈CE的IP CODE．根据使用环境分成：Dry Location/Damp Location/Wet Location．
13.2 Damp and wet location luminaires
13.2.1 General
13.2.1.1 Damp and wet location luminaires shall have electrical insulation material with moisture-resistant properties equivalent to treated cellulosic or vulcanized fiber, phenolic, urea, or ceramic. Untreated fiber shall not be used.
13.2.1.2 The lampholder screwshells of the luminaire shall be copper, copper alloy of at least 80 percent copper, nickel alloy, or stainless steel.
13.3 Damp location luminaires
13.3.1 Marking
13.3.1.1 A luminaire intended for use in damp locations that complies with the requirements of Clauses 13.2 and 13.3, as applicable, shall be marked in accordance with Table 20.1.1, Item 2.2.
13.3.1.2 A damp location luminaire shall not be provided with any markings, instructions, or illustrations, on the carton or with the luminaire, that imply that it is suitable for use, or depict its use, in a wet location. 貴司之產品看起來像是浴室使用, 而以定義來說, 浴室是damp location沒錯, 而不被定義在wet location, 但能否用尚需視您的材質, 如線材方面的披覆, 其它部位是否防潮, 而在damp location中UL的定義並無再加強說明其它測試, 故全以結構來看, 此點就變成有點見仁見智了, 每個工程師的觀點不同, 就全看您怎麼與之周旋, 但相信貴司若用料皆符合的話, 他們也無話可說, 您不妨不要問而直接送測時將條件直接設定在damp location反而會較好過. 刚有和认证工程师那边沟通过，此款灯可做成 Damp Location, 有两点需要注意就行了。
1. 灯头螺口不能为铝
2.玻璃罩需要一漏水孔，直径不小于5mm.
不好意思，忘了告诉大家此灯为美标UL1598 漏水孔不需要的，只有Wet 才要漏水孔。
