5.0 out of 5 stars WOW......Outstanding Product!!!!, November 12, 2009

Now I call THIS a book light. 16 LED lights make the light nice and bright. I especially like that there is an on and off switch. Most of the book lights I researched before I decided on this one had only one or two overhead LED lights which did not cast enough illumination and were flimsy. This product is well made and reasonably priced. In fact, I did not get mine on Amazon. Instead I bought it at a Lamps Plus which was liquidating its stock and paid only $12 dollars. What a DEAL!! Don't hesitate to buy this one.

This book light is an order of magnitude brighter than small clip-on book lights that use AAA batteries. As one would expect, it uses significantly more electricity and is heavier than alternatives. In my particular application, which is reading in a dim coffeehouse, I needed a portable desk light. With 16 LEDs and 10.5 watt-hours of electrical reserve (2600 mah AA batteries x 3 batteries x 1.35 volts), it does an excellent job. My only criticism is that the light appears to be lacking current-control circuitry that would allow the light to maintain relatively constant brightness as the batteries are depleted.

Out of curiosity, I connected the light to a digital power supply to determine how long the batteries should last under normal conditions. The tests indicate that this particular light lacks current control circuitry that all LED lights should have.That is to say, the current draw and light output varied dramatically with voltage. So, as your batteries are depleted, light output will drop. I was getting about a 0.7 amp draw at 4.5 volts (for alkaline batteries 3 x 1.5) and 0.5 amp draw at 4.0 volts which would approximate three NiMh batteries. This means that if the batteries could be depleted 100%, the batteries would last five hours. In reality, brightness and current draw will drop as the batteries lose power so the light will be visible much longer than five hours. It would be nice to have more sophisticated electronics, including a dimmer. However, at this price point, it is understandable why the manufacturer would omit the added expense of a separate circuit.

The brightness and light pattern are excellent. The array of 2 x 8 LEDs provide a rectangular beam that can be aligned to a both pages of an open book. The flexible neck makes it easy to adjust the direction of the light, which is nice if you are writing and taking notes. A nice design feature is the two extensible feet that provide extra stability for the lamp that is quite top heavy. The weight of the three AA batteries also helps in this regard. The clip is somewhat unnecessary as the light is too bulky to attach to most books. That being said, it still makes an excellent reading light when placed on a desk.


Pros
Uses AA batteries
Very bright for a battery power desk light
Excellent beam pattern for reading


Cons
No constant current circuitry/brightness varies with battery voltage
No dimmer
A bit bulky for clipping onto a book

I have six, that's right six of these wonderful gooseneck book lights. Not only are they wonderful for reading books and magazines at nightor in low light, but I keep one in the kitchen to attach to my cook book, one attached to my beading board when I make jewelry. I even got my husband to use his when he is working on the car! It attaches to anything. This is a wonderful product and I use it everyday.
