When you’re searching for the right reading light, you need to be mindful of both how and where it will be used. First, what size and type of book will it be used to light? If it only needs to light standard size so called mass market paperback books, a smaller, single LED or incandescent design will probably be sufficient. If your reading light must evenly light 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 like the warmer, slightly golden glow of an incandescent light or the whiter, more “sun like” output of modern LEDs.
Another significant consideration is the cost of maintenance. While LED and incandescent lights require about the same amount of power, discharging batteries with about equal speed, incandescent light sources have a life expectancy of between 15-25 hours of use. LEDs, while only slightly more expensive than incandescent designs, typically have life expectancies of between 5,000-50,000 hours of use. Obviously, LEDs will cost much less to service over the long run if the reading light will be used for more than 15-25 hours.
Many modern reading light designs offer the flexibility of running on batteries or optional A/C operation. Obviously, battery power is handy when the light is to be used anywhere an A/C outlet isn’t handy, but it can be expensive to replace batteries, as most fully charged alkaline batteries last only for approximately 20-30 hours of use. A good option to consider would be a good battery recharger and set of rechargeable batteries.
Finally, a reading light usually incorporates a sturdy clip that makes for easy attachment to your book, book holder or book stand. The clip can also be used to secure your reading light to a music stand, podium, desk, piano or organ music rack, etc, which greatly increases the possible uses for your reading light. Some designs offer an optional base or cradle which allows your reading light to be affixed to any ferrous surface, such as an appliance, an automotive fender, hood or trunk lid, etc. The potential applications are unlimited.
