USB COMPUTER LIGHT

USB Computer Light, retail $6.35*
Manufactured by (Unknown) for Greenbrier Int'l {Dollar Days}
Last updated 09-07-12

The Computer Light is pretty much that - a USB keyboard light.

This is a product designed to light your laptop computer's keyboard, using any free USB port on that computer to power itself.

It has a stiff but flexible stalk so you can direct (aim) the light anywhere you need it.

* This is the average (out of 5 units) going price for them on Ebay as of 09-06-12.

SIZE

To use the USB Computer Light, just plug it into any unused USB port on your computer, and orient it where you want to direct (aim) the light by bending its stiff but flexible stalk. Yes, it really is as easy as that.

Since this product draws the power it needs directly from the USB port it plugs into, I don't have to tell you about any battery changing procedures.

This product is "hot swappable", meaning you don't have to power down the computer before plugging in or unplugging this device. This is fairly typical of USB devices, so no surprise there.

I cannot measure the current consumption without chopping the unit up, and if I did that, I'd probably end up wrecking it for good.

The USB Computer Light is designed to be a computer peripheral, not a flashlight meant to be carried around, thrashed, and abused; so I won't try to drown it in the toliet tank, bash it against a steel rod or against the concrete floor of a patio, let my mother's big dog's ghost, her kitties, my sister's kitty cat, or my own little fuzzbomb spring a leak (uranate) on it, run over it with a 450lb Quickie motorised wheelchair, stomp on it, use a medium or large ball peen hammer in order to bash it open to check it for candiosity, fire it from the cannoñata, drop it down the top of Mt. Erupto (I guess I've been watching the TV program "Viva Piñata" too much again

- candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piñata Central {aka. "Party Central"}), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoñata (also located at Piñata Central) is only used to shoot piñatas to piñata parties away from picturesque Piñata Island, and Mt. Erupto is an active volcano on Piñata Island), send it to the Daystrom Institute for additional analysis, or perform other indecencies on it that a flashlight might have to have performed on it. So this section of the web page will be ***SIGNIFICANTLY*** more bare than this section of the web page on a page about a flashlight.

Despite its delicate appearance, the USB Computer Light seems to be reasonably durable and well-made.

This light has a single white LED in its head, and does a rather poor job at illuminating the surface it's aimed at.

It "ILLUMINATES" just fine, but in my opinion, the beam is too narrow to illumate an entire laptop computer keyboard!!!
Like I just said, its beam is narrower than I would have liked, but NOT unusably so.

Photograph of my computer keyboard illuminated almost solely by this light (a small amount of ambient light queered the photograph a bit, but you can still plainly see the bluish-white spot produced by this product).
Product is shown illuminating my keyboard from a rather low angle, that's why the beam terminus spot is ovoid and not circular.

Spectrographic analysis of the LED in this light.

Spectrographic analysis of the LED in this light; spectrometer's response narrowed to a band between 430nm and 470nm to pinpoint native emission peak wavelength, which is 451.927nm.

TEST NOTES:
Test unit was sent to me by D.K. from Philadelphia PA. USA on and was received on 08-31-12.

UPDATE: 00-00-00

PROS:
The price is right (O WAIT!!! Isn't that a TV game show?)
"Neck" is stiff but easily flexible
Does not require batteries of any type

CONS:
In my opinion, the beam is a bit too narrow to make an effective keyboard light
