The Forever Flashlight uses no batteries or bulbs. Instead it uses Faraday's Principle of Induction and a bright LED to produce light without batteries. The light is shaken for about 30 seconds to recharge a capacitor and it will then provide about 5 minutes of light. As the light is shaken, a magnet passes through a metal coil generating electricity. During prolonged use it can be shaken for 10-15 seconds every 2 or 3 minutes.I realize this wouldnt survive SHTF, but would this be a good device for brief instances where light is needed? :confused:

WHOOP! WHOOP! WHOOP!



GIMMICK ALERT! GIMMICK ALERT!

May I recommend a Streamlight Keymate instead. Price circa 13 bucks. LED, 4 watch batteries, purported 96 hour run time, bright as heck, looks like a tiny maglite, operates the same, keychain clip or a rather functional pocket clip that works great on shirt pockets. Not much bigger than a .45 Colt cartridge. No shaking required.

Sounds like a great flashlight for kidlets! Never needs batteries, and Mom always can hear when they are up, after lights out, 'cause of the flashlight being shaken!

In my reasonably well-informed opinion, if you want the best light for emergency situations (oh, hurricanes come to mind, but whatever), get a Streamlight 3C 10LED. As the name suggests, it has 10 LEDs and is powered by three C-cell batteries (and the half-used C-cells you can pull out of your kids' toys will work in this flashlight for a long time). It's rated for 350 hours, though the light intensity declines more-or-less linearly over that period. (Unlike incandescent bulbs, the LEDs themselves will not wear out until we are all dead.) Even if the rating is exaggerated, it's still good for 10 straight days of useful light. It's more of a soft floodlight than a narrow spotlight, which is ideal for indoors but also works fine outdoors. This light isn't intended for most uses (e.g., everyday carry, lighting up a target 100-yards away, etc.), but it's the best I've seen for emergency use.

And no, I'm not affiliated in any way with anyone mentioned above. I just wanted a really good emergency flashlight, researched it, bought a few, and this is my favorite. It's about $35.

Sorry skeptics but the shake ems have their uses...like leaving them in a car all winter when its real cold...they will always light up...

Have you seen their USB coffee heaters?

The most useful lights I've found outside my Sure-Fire and Pelican Black Knight are the Krills. I hang one inside my tent for use as primary soft lighting when hunting. They are the waterproof, cool-burning, battery operated replacements for chem lights and have 3000 hour lifespans. They will run 120 hour on one set of AA batteries and the Extremes run 50 hours.

Who makes Krill Lamps?

Krill -- I never heard of them.

Also, do they have a company website?

Thanks...
