Maglite water test
________________________________________
Because I built MEGALIGHTS out of common Maglites, I have heard concerns about the water resistance of the Maglite. (Not in this Forum)
When somebody printed the story that he had to dry the insides of one after a rain, I set to demonstrate what I knew all along.
As a watchmaker for 40 years I know what good seals can take, I am not saying that this is a dive light, but getting the inside wet after a rain is preposterous

Notice the water level and that the light is on.
This one took a bath for 20 minutes and come out completely dry inside, anybody with enough money to buy a Maglite can do this test.

Do you put patroleum jelly on your threads and rings? The paperwork that came with my mag said to but no one else I've ever talked to has even heard of that. Only problem I've ever had with my mag or the rechargables I've used, is the bulbs break way to easily on the rechargables when they are dropped.

Moose63845,
A little silicone grease in the threads is o.k. a little rubbed with your fingers in the o rings is o.k. too.
The part that you have to watch for is the very end of the flashlight body (where it is bright) and the matching recess in the tailcap (which is also bright) those are the areas that complete the electrical path.
They should be free of lube and kept dry and bright.
If you unescrew the tail-cap half a turn you cut the electrical path and put the flashlight "on safe"
That is the technique I recommend my customers of MEGA flashlights to use when they are around children, these light are very powerful at 951 lumens and 678 lumens and can cause temporarily blindness.

Thank you for your questions, and for visiting my thread

Scuba divers always lube the Orings to keep the water out. The water tends to seep in when you are turning the light on & off. Use a silicone grease on your Orings. I've taken dive lights to well below 100ft and never had a leak. It pays to lubricate.

Yes, if you are going to use a light underwater more silicon on the treads is appropiate.
Scuba divers use Dow Corning 111 or NyOgel
