*** VERY IMPORTANT!!! ***
I used a Molex pin remover to remove the power pins from the Molex connector on this product so I could connect it to an EPS for testing on this website.


The "Superbright Laser LED Cannon" is a small LED light module designed to be installed in your computer or in your automobile (with some minor modification). They consist of an LED & resistor module, a swivel base, and a set of Molex pass-through connectors with both male and female ends, so you can connect them inside your computer even if no spare power plugs are present.

The module is equipped with a thin power cable at least 12" (~30cm) long between the back of the module itself and the Molex plug it is connected to.


 SIZE



To use these, take the outer casing off your computer (first turning your computer off of course). Find a place you want to mount one of these. On the bottom of the black mounting plate is a piece of double-stick foam. Remove the red covering from it and press the module into place. Be sure the area you're affixing it to is clean and dry before mounting it - many computer cases are a bit dusty inside.

Connect the Molex pass-through connectors to any of the connectors in your PC case that are the same size and have four wires (one red, one yellow, and two black).

The LED module can pivot on its mounting a full 360 horizontally and 180 vertically, so you can direct (aim) the light anywhere you want it.

You can use it for automotive interior lighting if you cut the Molex connectors off and wire it up to +12 volts "the hard way". Yellow (or red) is (+) positive, black is (-) negative.

You can also use them for decorative lighting of appliques (use them behind the applique), statues, crystal, paintings, bathtubs, sinks, toliets, wall-mounted porcelain uranators, and other horse puckey by connecting them to a 12 volts DC "wall wart" that can furnish at least 30mA per light. As with automotive lighting applications, you'll have to snip off the Molex connectors and connect it (them) yourself. As above, yellow (or red) is (+) positive, black is (-) negative.



Because this product was designed to be connected to the +12 volt line in your computer, I do not have to tell you what kind of batteries it needs or which part to kick into the garden with all those hungry, hungry praying mantids.


Here is what a praying mantis looks like.

Current usage is not known, but is stated as 20-25mA at 12 volts.



This product is meant to be installed in a computer and then not {vulgar term for having had intercourse} with, not a flashlight meant to be carried around, thrashed, trashed, and abused. So I won't hit it against the concrete floor of a patio, throw it in the toilet, stomp on it, throw it against a wall, run over it with a 400lb electric wheelchair, let my housemate's cats take a leak on it, sit on it really hard, or subject it to any other potentially destructive tests that a regular flashlight might be subject to. So this section of the web page will appear SIGNIFICANTLY more bare than this section of the web page on a page about a flashlight.

One thing I noticed is that both units I purchased have very similar peak wavelengths, even though one package is marked "blue" and the other "purple". This similarity was verified by spectrographic analyses I performed on the two units. Whether this is just a packaging error or something more sinister remains to be seen.

As you can see, the blue and the violet are very close in wavelength to one another.

TEST NOTES:
Test units were purchased on Ebay and were received on 09-05-06.

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: 03-13-10
I performed spectroscopy of both units together, and did not see the "split" or "camel hump" spectrum I was expecting.
