When selected properly, a book light can reduce eye strain by assuring ample light while reading, even in the darkest places, and can conserve both energy and money. A well designed clip on book light design can make your light easy to securely attach to your book, book holder, or book stand, and many do double duty as craft, podium, hobby or other task lighting. Light weight incandescent or LED designs can put exactly the required amount of light exactly where you need it, without wasting energy or disturbing those around you, like a spouse or partner sleeping beside you.
By lighting your reading materials with just the correct 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 right amount of light for what we’re reading can be difficult. Obviously, the most perfect light for reading is natural sunlight coming directly over your shoulder, but we often have to read when or where sunlight isn’t available. Hence, the right book light, a light we can use anywhere and anytime we choose, iscan be} an incredible convenience. By then turning off the overheads and lamps lighting things other than our reading, we can save considerable energy and the money required to pay for that energy.
When making the choice between incandescent and LED designs, 3 primary concerns are: the differences in the type of light produced by these two technologies, the cost of acquisition, and the cost of maintenance and operation over the lifetime of the light. Incandescent light sources typically create a warm, somewhat yellowish or golden-tinged light, and incandescent 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 approximate the output of light from the sun. Today, most readers find the output of modern LED designs to be more “sun like”, producing greater contrast and making all printing easier to read. While replacement bulbs for many incandescent book light designs are readily available in local electrical and hardware stores, as well as over the Internet, the expense and inconvenience of replacement can really mount up over time. Because LEDs provide life expectancies of 10,000 to 50,000 hours, their 10-20% greater initial cost of acquisition quickly becomes irrelevant. For these and other reasons, LED book light designs are now more popular than the older incandescent.
Battery powered clip on lights are the handiest, since they can be used anywhere. Unfortunately, batteries too are a replaceable item, 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, and another option is to make use of rechargeable batteries and a recharger. Most book lights make use of either AA or AAA batteries, and many rechargeable options are on offer. In addition, if your light is to be used near to an electrical outlet, an optional A/C adapter can be a worthwhile investment.
Finally, the area over which the light is dispersed is also a consideration when selecting the right book light for a specific application. If your light will only be used to light up a standard mass market paperback book, a single LED or incandescent book light design will likely be sufficient; but, if you read mostly hard cover books, newspapers and magazines, or even a full music stand of sheet music, you’ll need a much more powerful light that distributes the lighting 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 dealer provides both good pre-sale and return service, just in case your first choice doesn’t work out. With diligence, you can find the perfect light for just about any use.
