ipx7產品防水等級
不代表就能極限使用
像防水手機，還是有人會進水
端看個人使用環境方式，或是歐令老化等等 都會影響
非必要就不要去試
與防水3c相比，我認為手電筒進水機會頗低

不好意思
另有兩個疑問

我的H600W有進水問題
之前騎腳踏車愈到下雨就進水了
沖水把泥巴沖掉也有進水一次
不死心O環抹一堆矽油膏想再試一次泡水十秒又再進水一次
不過之前問過期他人倒是沒進過水
所以我認為應該是個案

如果進水解 ...

Youtube上面的SC52拆解方法要謹慎使用，SC52的鏡片壓環是用緊配的方式嵌入燈頭，拆解者是用起子插入鏡片壓環與鏡片間之極小空隙，設法將緊配的壓環翹起，翹起時起子會對鏡片施力，施力若過大可能會使鏡片裂開.

Just to clarify, you actually had the lights on and started changing modes while submersed?

I only ask because the IPX-7 and IPX-8 ratings refer to water-immersed lights at specific depths and times, but do NOT cover actual activation or use. For that matter, they technically still allow water ingress, as long as it produces "no harmful effects". It is thus quite possible to pass IPX-8 testing (done with the light off) but have it fail immediately if you press the switch.

This is an important point, as people read too much into IPX ratings (i,e., the actual standard is not consistent with most people's intuitive understanding of "waterproof"). Only dive-rated lights are guaranteed to operate underwater without issue.

FYI, the ANSI FL-1 standards of "waterproof" and "submersible" are slightly more stringent than the IPX-7 and IPX-8 (upon which they are based), but even they don't cover lights in actual use - only submerged lights in the off state. Unfortunately, all bets are off if you turn the light on while submerged.

呃…
我想說
如果手電的「 防水」能做到水下操作
那潛水用的燈就不用賣得那麼貴了
不是嗎

完全看人品（匹配零件的尺寸公差），SC30的鏡片壓環仍然是用緊配法嵌入，與SC52/H502完全相同.
手電大家談也是有筒友講過如何打開SC52的鏡片壓環，他是用腳踏車內胎皮蓋在鏡片壓環，再以木柄抵住內胎皮，不費什麼力 ...
