I have an emisar d2 and dt8 and both are ip 67 but so far any time i tried to use them in wet conditions water got into the body. The strange thing is they didnt actually break they just acted strange for a while and then after drying for a night everything seemed okay. Except my trust in emisar. They are both amazing lights but im always extremely carefull now when using them. Kinda dissapointed. Wanted to do a nld post about my dt8 but this how it ended up. Extra details: they both fogged up, the d2 didnt really turn off correctly. The dt8 worked perfectly for hours after submersion in water but when i changed the battery i noticed the head was audably and visibly bubbling water when i screwed on the cap.
