Properly selected, 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 sturdy clip on book light design can make your light easy to secure to your book, book holder, or book stand, and many designs can also function as hobby, craft, podium or task lights. Light weight incandescent or LED designs can put exactly the required lighting exactly where you need it, without wasting energy or disturbing others around you, like a spouse or partner on the other side of the bed.

By lighting your reading materials with the correct amount and temperature of light, a book light can save your eyes from strain and help you read even when the lights are low. Our eyes require more light as we age, and providing the right amount of light exactly where we’re reading can be a real challenge. Obviously, the most perfect light for reading is natural sunlight coming directly over your shoulder, but we often wish to read when or where sunlight simply isn’t available. Hence, the correctly selected book light, one we can use anywhere and anytime we choose, iscan be} an incredible convenience. Then, turning off the overheads and lamps illuminating so much more than our reading materials, we conserve considerable energy and the money required to pay for that energy.

When choosing between incandescent and LED book light designs, 3 primary considerations include: the differences in the type of light produced by these two technologies, the cost of original purchase, and the cost of operation over the lifetime of the light. Incandescent light sources typically produce a warm, somewhat yellowish or golden-tinged light, and incandescent bulbs typically last between 15-25 hours of use and then have to be replaced. LED lights create a whiter, cooler light, and many designs are now optimized to approximate the output of light from the sun. Today, many book lovers find the output 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 readily available in local stores, as well as over the Internet, the cost of replacement can really add up over time. Because LEDs provide life expectancies of 10,000 to 50,000 hours, the 10-20% greater initial cost of acquisition quickly becomes irrelevant. For these and other reasons, LED book lights are now more popular than the older incandescent.

Battery powered book light designs are the handiest, as your light can be used virtually anywhere. Unfortunately, batteries too are a an item that must be replaced, typically lasting only 20-30 hours of use at best, in either LED or incandescent designs. Available A/C adapters are offered for most book lights, but another option is to make use of a good battery recharger and rechargeable batteries. Most book lights use either AA or AAA batteries, and many rechargeable options exist. In addition, if your light is to be used close to an electrical outlet, an optional A/C adapter is usually a money saving investment.

Finally, the uniformity of light dispersal and the area over which it is dispersed is also an important consideration when identifying the best book light for a specific application. If your light is only to be used to illuminate a standard mass market paperback book, a simple LED or incandescent portable design will probably be sufficient; but, if you read mostly hard cover books, newspapers and magazines, or even a full music stand of sheet music, you’ll want a much more powerful design which distributes the lighting over an appropriately larger area. The best way to determine the best light for your particular application will be to test it in actual use. Wherever you shop, be sure your dealer provides both good pre-sale and return service, in case your first choice turns out not to be as suitable as you had hoped. With a bit of application, you can find the best light for any use.
