The ETG Strobe is a type of LED "rave light". It features a red and a pure green LED, plus an IC that flashes the two rapidly in a predetermined sequence.
It is equipped with a tiny but very powerful magnet that allows you to affix the tiny light to various places, including clothing, body parts like lips or ears; or to ferrous surfaces like bicycles and metal components of automobiles.
To use the ETG Strobe, just give it a gentle but firm clockwise twist. Careful, not TOO hard. Turning it off is just as easy; twist the other way until it goes off.
It comes equipped with a small, thin disk magnet; you can use this to affix the light to clothing, thin body parts (earlobes work especially well), or other thin surfaces. The magnet will "suck" the body of the light through a surprisingly thick material; they're quite powerful. A second magnet is built into the bottom of the light; this gives it that extra grab.
Because this light use powerful magnets, you should not use or carry one in the same pocket as your bank card or other card with a black or brown magnetic stripe on the back, and you should not bring it within a foot of computer diskettes, computer hard drives, music cassettes, cassette players or walkmans; or video tapes & players. These lights will also cause discoloration of the picture on TV screens and computer monitors if brought to within 2" or so of the screen or placed on top of the set, so you should not store or leave these things on top of the TV between uses. When not being used, sticking them to a larger piece of ferrous metal, such as the refrigerator or a metal doorframe, greatly reduces the emitted magnetic field so your bank card won't become scrambled if you happen to walk by the light with your wallet in your hands. :)
To change the batteries in your ETG Strobe, unscrew the two halves until they come apart. Remove the three SR626SW silver oxide cells from the bottom half of the light, removing and using the disc magnet on the bottom to "pull out" that last cell if necessary. There should be a black plastic cylinder the cells fit in; remove that and set it aside before disposing of the dead batteries.
Place three new cells in the light's body, orienting them so the flat (+) side is downward. Try to put that first cell in so it's in the center of the chamber, as best as you can get it. Use the tip of a pen to move the cell to the center if necessary. Lay the other cells on top of it, being sure the flat (+) side faces down. With all three cells in there, slide that black plastic cylinder over them, so the top two cells are covered on their sides by it. This is important, because it prevents the two topmost cells from touching the walls of the battery chamber.
Check the insides of the top piece to be sure the black plastic "doughnut" has not come out. If it has (or if it stuck to the uppermost cell), place it back inside the light.
Screw the two halves of the light back together, and back off a bit once it springs to life.
If you love shiny, blinky things, you'll love the ETG Strobe.
Using the magnetic disk, clip it to clothes, earlobes, etc., or stick it to bicycle or car frames (any iron or steel surfaces) with the same magnet, and turn it on when you really want to light up that next party or rave you go to.
The ETG Strobe produces a wide, 180 degree swath of light. Although it isn't meant to be used as a flashlight, you could use it as one if the need comes up.
The strobe effect appears to be two or three green flashes, a brief pause, two or three red flashes, then another brief pause. Lather, rinse, repeat - just like it says on the back of the shampoo bottle. These flashes are pretty fast, so I can't get an accurate count on them.
I don't think the ETG Strobe is waterproof, so be careful at the urinator or toilet so that it doesn't fall in when nature calls.

I don't know exactly WHEN the test sample was received; suffice it to say it was quite a ways back, and I apologise for the delay in getting it on my website.
Today is 10-17-03 (when I found the envelope while looking for my Pink Floyd "Dark Side of the Moon" CD), if it means anything.
