These are way-cool necklaces that have six flashing LEDs in them - including a fuchsia one - a color I have never before seen in an LED. So I attempted to take a spectrum of it - and surprisingly, did meet with a limited measure of success.

The LEDs just don't flash in unison (together); they flash in a "chasing" pattern that gives the illusion of rotation (spinning).

There are six necklaces in the pack; this equates to a price of just ~$2.49 apiece.


The necklace comes ready to use right out of the bag.

To activate it, look on the back of the necklace for a fatter segment, and look for a black plastic thing at one side of that segment. Pull it out, and place it somewhere safe.

Push in on the two ends of the necklace where they go into that fatter segment. One end of the necklace should move into that fatter segment with a "click" sound; the LEDs should then be flashing.

Put the necklace on over your head, orienting it so that the fatter segment is positioned near the back of your head. Positioning is not crucial here, so if the necklace rotates while you're using it, you need not worry about it or go out of your way to correct it.

To turn the necklace off, gently pull the ends of the necklace apart until you hear a click, then insert that black plastic thing into the groove that should now be visible between one of the necklace ends and that fatter piece. This piece helps ensure the necklace stays off during storage or transport; although its presence is not critical, it does help ensure the necklace does not become accidentally activated. Since it appears to be a disposable product, this piece helps to ensure greater battery life.

I've already broken the black plastic thing from one of the necklaces, but since I must reiterate that it is not a component critical to its operation, the rating I give this product will not be affected much, if at all.

This product appears to be disposable, so I don't have battery changing instructions for you today.

I was able to remove one side of the necklace and then remove the transparent plastic sleeve from around the battery compartment, but could go no further.

Due to how the product was constructed and how it operates, I am not able to furnish you with a currect usage value.

Because this is a novelty item and not a flashlight meant to be thrashed, trashed, and abused, I won't throw it against the wall, stomp on it, try to drown it in the toylet bowl or the cistern, run over it, swing it against the concrete floor of a patio, bash it open to check it for candiosity, fire it from the cannonada (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a scanner-type device on a platform with a large readout or with a handheld wand), send it to the Daystrom Institute for additional analysis, or inflict upon it punishments that flashlights may have inflicted upon them.

The LED 6-Light Necklace is not water-resistant or submersible, therefore, water, milk, diet vanilla Pepsi, cold (or hot) coffee, urine, ice cold fizzy root beer, disposable douches, disposable enemas, tranny fluid, gasoline, diesel, jet fuel, brake fluid, motor oil, or other liquids could get inside. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, snowbanks, puddles of blue whale pee, tall cold glasses (or short lukewarm glasses) of milk, slush piles, mud puddles, tubs, root beer floats, toilet bowls, cisterns, sinks, cups of coffee (hot *OR* cold), fishtanks, dog water dishes, old yucky wet mops, wall-mounted porcelain urinators, leaky water heaters, busted garden hoses, puddles of antifreeze, brake fluid, tranny fluid, gasoline, or other places where water or water-like liquids might be found. And you'll probably want to cover it up or otherwise get rid of it (such as by putting it in a very large pocket or in a bag) if you need to carry it in rainy or snowy weather.

If it fell in water and you suspect it got flooded, dump out the water if necessary, and set it in a warm dry place for a day or so just to be sure it's completely dry inside before you use it again.

If it fell into seawater, got thrown into a glass of milk, if it fell in a root beer float, if it fell into a bowl of "soft-serv" ice cream, if somebody squirted a Summer's Eve brand post-menstrual disposable douche or a Fleet brand disposable enema at it (and hit it with the douche or the enema), or if somebody or something peed on it, rinse it out with fresh water before setting it out to dry. You don't want your necklace to smell like seaweed, sour milk, flowers, fresh butts, or rotten piss when you go to use it next. Besides, salt (from seawater, disposable douches, disposable enemas, or urination), lactic acid (from moo juice), glycerol (from antifreeze), or sugar (from root beer & ice cream) can't be very good for the insides.

Photograph of the unit in operation.
Only two of the LEDs are illuminated here because the six LEDs flash in a "chasing" pattern.

Photograph of the unit in operation.
Same as above, but I wanted to show that fuchsia LED.

Here is a closeup of that fuchsia LED I harvested from one of the units.

Spectrographic plot
Spectrometer plot of the fuchsia LED in this necklace.
This LED is flashing, not steady, so I was unable to obtain a full-height spectrum of it.

WMP movie (.avi extension) showing the necklace's flashing action.
This clip is approximately 3.9 megabytes (4,055,694 bytes) in length; dial-up users please be aware.
It will take no less than eighteen minutes to load at 48.0Kbps.

The music from the Sega coin-op arcade video game "Afterburner Deluxe" from 1987 was on when this was recorded.
This product is not sound-ensitive; the music may be ignored or muted if desired.

I cannot provide it in other formats, so please do not ask.

Test units (they only come in packs of six) were purchased from the Oriental Trading website on 07-26-07, and were received on the afternoon of 08-03-07.

Product was made in China.
A product's country of origin really does matter to some people, which is why I published it on this web page.

UPDATE: 08-08-07
I intentionally destroyed one of the necklaces *specifically* to harvest that fuchsia LED for additional analysis. The leads are too short for it to fit the sockets of my LED tester, but I will attempt to connect it via another means so that I can perform spectroscopy of it in CW (not blinking) mode.

I'll attempt spectroscopy of this LED probably later this afternoon.

UPDATE: 08-10-07
I have not yet performed the spectroscopy because the LED's leads are too short to fit my LED power supply and I have not yet found the other micro clip power lead that would be necessary to power the LED with (I have one at my disposal; I need to find the other).
