Waterproof test

   SP11-S flashlight waterproof is ipx-8 level,2 meters underwater is 30 minutes,before flashlight all the datas comply with the official,so i much trust with SP11-S.Can’t find the 2 meters underwater for flashlight test sites,so used the standby,put it to 10 CM deep pool(after all few people will trutly flashlight used for underwater lighting,in addition to the professional diving flashlight),if it can be normal on-off and swutch gear,the proformance is not bad!
