When you’re looking for the right reading light, it is helpful to consider both where and how it will be used. First, what size and type of book will your light be used to illuminate? If it needs only to light standard size so called mass market paperbacks, a smaller, single incandescent or LED design will likely be fine. If it must light up a coffee table book, then you’ll need a light designed for considerably greater light output evenly distributed over a significantly larger area. Another thing to consider is whether you prefer the warmer, slightly golden glow of an incandescent light or the whiter, cooler output of modern LEDs.
Another important consideration is that of maintenance. While both incandescent and LED reading lights require approximately the same amount of power, using up batteries with about equal speed, incandescent bulbs have a life expectancy of between 15-25 hours of use. LEDs, while only slightly more expensive than incandescent designs, usually provide lifetimes between 5,000-50,000 hours of use. Obviously, LEDs will be significantly less expensive to maintain over the long run if the reading light will be used regularly.
Most modern reading light designs provide the flexibility of running on batteries or optional A/C operation. Obviously, battery power is handy when the light is to be used where an A/C outlet isn’t close, but it can be expensive to replace batteries, as most new alkaline batteries will last only for about 20-30 hours of use. A good alternative to consider would be a good recharger and rechargeable batteries.
Finally, a reading light usually incorporates a clip which securely attaches to your book, book stand or book holder. The clip can also be used to attach your reading light to a music stand, podium, desk, piano or organ music rack, etc, which exponentially increases the range of uses for your light. Some designs offer an optional base or cradle that allows your clip on reading light to be secured to any ferrous surface, such as an appliance, a car fender, hood or trunk lid, etc. The potential applications are truly unlimited.
