Shakelight reviews?

    Is the Shakelight flashlight (which uses the Faraday principle instead
    of batteries) as good as I hear? Any drawbacks?
    I see many imitations on the market. Are any of them as good?

    Thanks,
    Greg
     
  2. Don't know if the one I used was a decent model or not but it was
    worthless while trying to change a flat tire, in the blowing snow at
    midnight of this Thanksgiving, I was shaking it more than working and in
    the end my lighter was a better source of light.
     
  3. Seem pricey to me for what you get.
    I grabbed a couple "imitations" at the local Walgreen's (two for
    ten bucks) and they're OK.

    They come in a box with no obvious way to tell who makes them,
    and all the text is in Direct Translation From Some Chinese Dialect
    To English By Someone Who Speaks Neither; near as I can tell the
    brand name is "THE NEW PRODUCT COME INTO THE MARKET" and below that
    text there's an illo of the thing shining a beam onto more text:
    "Environment-protective torch for 21st century". (There's a list of
    "Features" on the side of the box that reads as if you're _supposed_
    to laugh out loud while reading).

    The light itself is in what looks and feels like a fairly strong
    clear plastic case with rows of little bumps down the sides, and
    it's easy to see the two CR2032 batteries in it...

    Still, take the batteries out (unscrew cap, pluck lens _with
    o-ring_ off, shake until guts slide out in one piece) and you still
    get a good ten minutes of light after a minute or so of shaking
    which (considering the circuit comprises the induction coil, diode
    bridge, 5.5V .2F cap paralleled with the batteries, and a 150 ohm
    load resistor for the single bluish-white LED) ain't too shabby.

    And not just "enough light to find a real flashlight with"
    either; I can see across the street with it.

    IMNSHO a decent stocking stuffer, even if the box looks like a
    deliberate stereotyped Oriental-product joke.

    How about those lights that are charged by hand-crank? Walgreens has
    one called the "Illuminator" or something. It's supposed to work for
    an hour without cranking. I just wonder if the crank will break.

  6. More like ten minutes or so, with one of the three LEDs lit. With
    all three, about two minutes.

    And I broke the handle off the crank when I dropped it. Gorilla
    Glue fixed it fine.

    The Shakelight clone is a better deal IMO especially as I use it
    as a bike headlight bungeed to the handlebars; shake as you go!
