3xLED BOOK LIGHT

3xLED Book Light, retail $14.99 (http://www.compusa.com...)
Manufactured by Great Point Light (www.greatpointlight)
Last updated 06-21-06




The 3xLED Book Light is just that: an LED book light that clips to the cover of a book and illuminates the pages of that book when you're in a dark room.

The housing is composed of a light blue plastic, and it features three wide-angle white LEDs in a head that swivels a full 360° in either direction. It has a flip-up body that also swivels 360° in either direction, and a clip on the base fits the cover of just about any book you want to shove it in.


SIZE



The book light is ready to use as soon as you remove it from the package.

Lift the middle portion of the housing up, and clip the base into the cover of a book. On the top of the unit, there is a small pushbutton switch - press & release the button once for high mode, press & release it again to switch it to low mode, and press & release it a third time to turn the unit off.

When you're finished reading, remove the book light from the book, and position all of its moveable components so they line up.



To change the batteries, slide the battery door/clip toward the top of the clip, lift it off, and set it aside.

If necessary, remove and dispose of or recycle the two CR2450 cells.

Insert two new CR2450 lithium coin cells into the holders, button-side (-) negative facing down.

Slide the battery door/clip back on; slide it until it locks into place.

Due to the way the product was constructed, I am not able to obtain a current usage measurement for you.



This product is meant to be used as a reading light in a dry area, so I won't try to drown it in the toilet, bash it against the floor of a concrete patio or a steel rod, let my housemate's kitties go wee-wee on it, run over it with a 450lb Celebrity, or perform other indecencies on it that a regular 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.

Most of the remaining content will just be the two photographs and the spectrometer plot below.

I tested it with a book about used up old insolators (17"W by 11"H when open), and although it did illuminated the pages adequately, I'd prefer to use it in a book with smaller pages, such as a paperback novel. I do not have such a book though (they were left behind after I moved on 10-11-04), so I cannot test the book light in that manner.

According to the packaging, it can be used to see "books, maps, laptop keyboards, and more".

The unit folds flat for easy storage in a purse or bag, and easy transport in a briefcase or pants pocket.
