When selected properly, a book light can reduce eye fatigue by providing excellent lighting while reading, even in the darkest places, and can help to conserve both energy and money. A well designed clip on book light design can make your light easy to attach to your book, book holder, or book stand, and many can do double duty as hobby, craft, podium or task lights. Light weight incandescent or LED designs can put exactly the required amount of light anywhere you need it, without wasting energy or disturbing those around you, like a spouse or partner sleeping beside you.

By illuminating your reading materials with the right quantity and temperature of light, the right book light can help to save your eyes from strain and assist your reading in darkened venues. Our eyes require more light as we age, and providing the correct amount of light exactly where we’re reading can be a real challenge. Obviously, the best light for reading is natural sunlight coming directly over your shoulder, but we often need to read when or where such lighting simply isn’t available. Hence, the correctly selected book light, one we can use any time and any place we choose, iscan be} an incredible convenience. Then, turning off the overheads and other lighting illuminating so much more than our reading materials, we conserve considerable energy and the money required to pay for it.

When making the choice between incandescent and LED book light designs, 3 primary considerations include: the differences in the type of light produced by these two distinct technologies, the cost of original purchase, and the cost of operation over the lifetime of the light. Incandescent light sources typically create a warm, somewhat golden-tinged light, and bulbs typically will provide light between 15-25 hours of use and then must be replaced. LED lights put out a whiter, cooler light, with many designs now optimized to be the equivalent of the output of light from the sun. Hence, most book lovers find the light of modern LEDs to be more “sun like”, producing greater clarity and contrast and making all printing easier to read. While replacement bulbs for many incandescent book light designs are usually available in local stores, and over the Internet, the cost of replacement can really mount up over time. Because LEDs offer life expectancies of 10,000 to 50,000 hours, the 10-20% greater initial cost of acquisition quickly becomes irrelevant. Generally, LED lights are now the preferred choice over the older incandescent.

Battery powered clip on lights are the handiest, since your light can be used almost anywhere. Unfortunately, batteries too are a an item that must be replaced, typically lasting only 20-30 hours of use at best, in LED or incandescent designs. Optional A/C adapters are offered for most book lights, and another option is to use rechargeable batteries and a recharger. Most book lights use either AA or AAA batteries, and many excellent models are available from which to choose. In addition, if your light is to be used close to an A/C outlet, an optional A/C adapter is usually a worthwhile investment.

Finally, the uniformity of light dispersal and the area over which it is dispersed is also a consideration when selecting the best book light for a particular application. If your light is only to be used to light a standard size, mass market paperback, a single LED or incandescent book light design will probably be sufficient; however, if you read magazines, most hard cover books or a stand full of music, you’ll want a more powerful design which can distribute the light over a much broader area. The best way to determine the best design for your particular application will be to test it in actual use. When shopping, be sure your retailer provides both good information and advice before the sale, and a good return policy, just in case your first choice turns out not to be as suitable as you had hoped. With diligence, you can acquire just the right clip-on book light for just about any use.
