Properly selected, a book light can reduce eye stress by providing excellent lighting while reading, even in darkened venues, and can conserve both energy and money. A sturdy clip on book light design can make your light easy to securely attach 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 just the right amount of light exactly where you need it, without wasting energy or disturbing those around you, like a spouse or partner on the other side of the bed.

By lighting your reading materials with the right amount and color of light, a book light can 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 difficult. Obviously, the best light for reading is natural sunlight coming directly from over your shoulder, but we often wish to read when or where sunlight isn’t available. Hence, the right book light, one we can use anywhere and anytime we choose, iscan be} an incredible convenience. By then turning off the overheads and other lighting illuminating so much more than our reading materials, we can save considerable energy as well as the money required to pay for that energy.

When choosing between incandescent and LED designs, three primary considerations are: the different color or temperature of light produced by these two distinct technologies, the cost of acquisition, and the cost of maintenance and operation over time. Incandescent light sources typically produce a warm, somewhat yellowish or golden-tinged light, and incandescent bulbs typically will provide light 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 be the equivalent of the output of lighting from the sun. Today, most readers find the output of modern LEDs to be more “sun like”, producing greater clarity and contrast and making most printing easier to read. While replacement bulbs for many incandescent book light designs are generally available in local electronic retail shops, and over the Internet, the expense and inconvenience of replacement can really mount up over time. Since 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 lights are now the preferred choice over the older incandescent.

Battery powered book lights are the handiest, because your light can be used virtually anywhere. Unfortunately, batteries themselves are also a an item that must be replaced, lasting 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 make use of a good battery recharger and rechargeable batteries. Most book light designs make use of either AA or AAA batteries, and many rechargeable options are on offer. Additionally, if your light is to be used near to an electrical outlet, an optionally available A/C adapter is usually a worthwhile investment.

Finally, the area over which the light is dispersed is also a consideration when choosing the perfect book light for a specific application. If your light is only to be used to illuminate a standard size, mass market paperback, a single LED or incandescent portable design will likely be sufficient; however, if you read magazines, most hard cover books or a stand full of music, you’ll want a much more powerful design which can distribute the light over an appropriately larger area. The best way to determine the most perfect light for any particular application will be to test it in actual use. When shopping, be sure your dealer provides both good pre-sale and return service, just in case your first choice doesn’t work out. With diligence, you can buy the perfect portable light for just about any application.
