Advantages of LED Light:
The operational life of current white LED lamps is 100,000 hours. This is 11 years of continuous operation, or 22 years of 50% operation. The long operational life of an led lamp is a stark contrast to the average life of an incandescent bulb, which is approximately 5000 hours. If the lighting device needs to be embedded into a very inaccessible place, using LEDs would virtually eliminate the need for routine bulb replacement.There is no comparison between the cost of LED lights vs. traditional incandescent options. With incandescent bulbs, the true cost of the bulb is the cost of replacement bulbs and the labor expense and time needed to replace them. These are significant factors, especially where there are a large number of installed bulbs. For office buildings and skyscrapers, maintenance costs to replace bulbs can be enormous. These issues can all be virtually eliminated with the LED option.
The key strength of LED lighting is reduced power consumption. When designed properly, an LED circuit will approach 80% efficiency, which means 80% of the electrical energy is converted to light energy. The remaining 20% is lost as heat energy. Compare that with incandescent bulbs which operate at about 20% efficiency (80% of the electrical energy is lost as heat). In real money terms, if a 100 Watt incandescent bulb is used for 1 year, with an electrical cost of 10 cents/kilowatt hour, $88 will be spent on electricity costs. Of the $88 expense, $70 will have been used to heat the room, not light the room. If an 80% efficient LED system had been used, the electricity cost would be $23 per year - there would be a cost savings of $65 on electricity during the year. Realistically the cost savings would be higher as most incandescent light bulbs blow out within a year and require replacements whereas LED light bulbs can be used easily for a decade without burning out.

04-30-2011- Other Thoughts: Lights the whole keyboard. <br/>Another review states that the wire isn't stiff enough to hold up the light, but the one I received is plenty stiff yet flexible. It stays exactly where I put it without a loopy knot.

04-09-2011- Other Thoughts: For the fact that it's not too sturdy. For one thing, the flex neck is a bit weak -- but then what do you want for a product that is so inexpensive? It would be great if they made another version that was more sturdy, even if it was 2 or 3 times the price.

03-12-2011- Other Thoughts: This is the perfect amount of light for me. Great for being able to see the keyboard at night, with all other lights off, and not blinding, lol.

02-28-2011- Other Thoughts: Bought this to be used with my Asus Eee laptop...but have found that any place I have a USB connector...this lamp is more than useful. Even use it with my desktop system when I don't want to heat up the room with the overhead lights.

02-12-2011- Other Thoughts: The best way to position it seems to be over the top if a laptop if your screen isn't too large, leaning against something, or I have figured out how to tie a loopy-knot type thing that allows it to support itself. But, USB light and/or fan people are already used to this weakness. A switch would also have been a good thing. This is really only evident if you have a self powered USB hub or only need it at night; but I have to say it is a pain having to unplug the light whenever I don't need it. <br/>Overall this is an improvement of most previous attempts at USB lighting. It addresses a problem without hurting the wallet and does a great job.

01-15-2011- Pros: I use this on my hackintosh netbook without an illuminated keyboard. It's nice to be able to see what I'm typing....
- Cons: Not bright ENOUGH. Buy one with 2 or 3 LEDS
- Other Thoughts: It would be better with a longer cord/snake .
