SOLAR CHARGED FLASHLIGHT

Solar Charged Flashlight, retail $11.98 (www.surplusshed.com...)
Manufactured by Gama Sonic (www.gamasonic.com)
Last updated 08-29-07




The Solar Charged Flashlight is a small, keychain-sized flashlight that uses two white LEDs, and features a solar panel on top to charge the internal batteries. So you'll never have to purchase disposable cells for it.

It attaches to your keychain with a spring-loaded lobster claw clasp on a swivel.


SIZE



To use this flashlight, be sure it is charged first (see directly below), and then you can go paint the town red - or white.

Press and hold the button on the top of the flashlight to turn it on; release the button to turn it off.
Things just don't get much easier than this...well, not flashlights, anyway.



This product uses rechargeable batteries, so I don't need to provide changing instructions here.

To charge this flashlight, leave it in a sunny window or other sunny location, solar panel side up, for at least one full day (eight to ten hours of sunlight), as shown in the photograph directly below.



The package reads "Requires a minimum 30min solar charge for operation".



This flashlight seems *reasonably* durable, but it's not indestructible. It only costs $12 though, so if you break it, you can easily buy another and not have to get too worried about it.

It is lightly weather- and splatter-resistant, but it is not waterproof or submersible. When suctioned, air had no problems getting through, and I don't see any signs of environmental protection (such as O-rings) either. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of wolf pee, slush piles, mud puddles, tubs, toilet bowls, cisterns, sinks, fishtanks, dog water dishes, or other places where water or water-like liquids might be found. A little rain or snow probably wouldn't hurt it though, so you need not be too concerned about using it in a light sprinkle.
