I have the above MTe P7 with 18650 battery. Makes a good helmet light , and at the price ideal for the amount of night riding i actually do.
I use it at work , and having taken some Tramadol (bad back pain) decided to accidently drop the torch into a 180 gallon tank of beer that I was fillling up. The other 2 tanks had everso slightly smaller vents and the torch would sit about 10 mm in and go no further. The last tanks vent was about 4mm bigger so i placed the torch into the vent , expecting it to stop , but it plopped straight in. Into about 60cm of beer!
Alot of swearing , and a quick reverse on the pump connections, and 15 minutes later the tank is almost empty.
As it was emptying I could see the bloody thing glowing away in the bottom of the tank . I was amazed it was still going. I hooked it out , reversed the pump connections again and refilled the tank . The main battery compartment had leaked and there was some beer on the battery, Couldn't see any sign of beer around the emitter, or in teh tailcap, as a precaution I left it to dry near one of the burners, after wiping aaway most of the beer .
Its still working fine today, how long that lasts remains to be seen, but total submersion , for about 15 mins , into beer and it seems OK must be a harsher test than a drizzly night ride.
