Flashlight in plastic bag?

[nigelfromramsgate]

I've read through posts in the Accessories/Lights forum and there is good information on dive lights in the $50 - $100 range. But couldn't I just take an ordinary 5w LED flashlight, pop it inside a ziploc bag (or, better, a Foodsaver type of vacuum-bag) for looking in crannies and under ledges?

For those purposes, there are plenty of $15 +/- out there.

For $20, this is my workhorse of a flash light

That light is my primary light on night dives too.

Links are from ScubaToys. Thanks guys

Edit: Once you get that bag under additional water pressure, I don't know how water tight it will remain.

Any flashlight with internal air spaces that is not designed for high pressure will only last until you get to its crush depth. That could be quite shallow.

Ziploc bags are for sandwiches, not lights. For the amount of money you spend on a non-diving LED light, you could probably get a diving specific one. There are always people selling used lights on here as well.

For 3 -5 feet maybe. Most lenses on non-diving lights are thin plastic.

Ziploc bags are not pressure vessels. No one said diving was cheap but you can find some inexpensive lights that will serve most rec. divers well.

Hi,

in this ocasion it maybe better to stay out of the water to avoid any troubles and losts of equipment.

Nice Dives

The Pelican 2010 Sabrelight is about $50 US, and it's almost as bright at the PrincetonTec Shockwave. (I have both plus the PT Torrent.) The only downside to the light is the twist-off. If it had a switch, I'd call it a perfect light.

One of the problems with non-dive lights is that even if they survive the trip, the switches tend to activate at depth due to the pressure.

Ziplocs aren't leakproof once under the least bit of pressure. I know this first hand. So your possibly busted light will be wet too.

You can buy a light designed for the purpose for pretty inexpensively.
