Looking at going snorkeling / swimming in the San Marcos river (in San Marcos, TX) with a Surefire L2. And while they said it was waterproof, I would just like to make sure...

Hrm, their web page says "O-ring sealed, weatherproof" and doesn't even mention a depth. I'd give it 10 minutes of snorkeling, tops. I've had flashlights that explicitly claimed waterproof that couldn't handle snorkeling and these guys aren't even going that far. Really need to get one designed for diving/prolonged swims.
Surefires have O-ring construction that is quite waterproof when properly lubricated. I believe that they're constructed so that water pressure increases the effective pressure in the seals by forcing the parts harder against the O-rings. IIRC from reading CPF, they're perfectly fine for snorkeling depths. They're not appropriate for diving depths because the water pressure pushes the push-button switch on constantly.Originally posted by: Fullmetal Chocobo

The waterproof depth is probably an old estimate. My guess is that Surefire removed it from its product literature/advertising because it wasn't having tests run at certification laboratories. I consulted an E1e/E2e Owner Handbook dated 2001, and the exact wording is "Water Resistant O-Ring Sealed", matching the current wording on the Surefire website. Of course, the anecdotal evidence shows that their actual maximum depth is greater than 10 meters.
