When you’re searching for the right reading light, you should to consider both where and how it will be used. First, what size and type of book will your light be used to light? If it needs only to light standard size so called mass market paperback books, a smaller, single incandescent or LED design will probably be fine. If your reading light must evenly light a large dictionary, then you’ll need a light designed for much greater light output evenly distributed over a considerably larger area. Another consideration is whether you like the warmer, slightly yellowish glow of an incandescent light source or the whiter, cooler output of modern LEDs.
Another important consideration is that of maintenance. While LED and incandescent lights require about the same amount of power, using up batteries with about equal speed, incandescent designs have a life expectancy of between 15-25 hours of use. LEDs, while only slightly more expensive than incandescent designs, typically provide lifetimes between 5,000-50,000 hours of use. Obviously, LEDs will cost much less to operate over the long haul if the light will be used for more than 15-25 hours.
Most modern reading light designs offer the flexibility of running on batteries or A/C operation. Obviously, battery power is handy when the light will be used anywhere an A/C outlet isn’t handy, but it can get expensive to replace batteries, as most fully charged alkaline batteries will last only for approximately 20-30 hours of use. A good alternative to consider would be a good recharger and set of rechargeable batteries.
Lastly, a reading light typically incorporates a sturdy clip which allows the light to be securely attached to your book, book holder or book stand. The clip can also be used to secure your reading light to a podium, music stand or piano music rack, which exponentially increases the uses for your light. Some designs also offer an optional cradle which allows your reading light to be mounted to any ferrous surface, such as an appliance, a car fender, hood or trunk lid, etc. The potential uses are truly unlimited.
