Many people like to install reading lamps near their bedsides so that they can lie in bed and read until they fall asleep. The type of reading lamps that you choose can vary depending on personal preference and the practical necessities of the room's configuration. Consider the Size of your Bedside Table Most bedside tables are not deep enough to accommodate a large reading lamp. Usually there is room for an alarm clock, glass of water, and the book you were reading. If you have a particularly shallow table, you may want to purchase reading lamps that attach directly to the wall. Wall mounted reading lamps do not take up any table space and can be more convenient to reach from a lying down position. There are many wall mounted reading lamps that can be swiveled closer or further away from the bed so that you will have more light when you need it. Will Someone Else Sleep While You Read? If you share the room with someone else, you will need to consider how large your bedside lamp is. You do not want to keep anyone else awake if you decide to continue reading late into the night. Reading lamps that have directly focused beams may be ideal for someone who shares a bed. Book lamps are a convenient way to shine light on the page you are reading without causing the room to be brighter. Many personal reading lamps have clips that allow them to hook directly on the book cover so that the light is focused right where you need it. How Warm are the Bulbs Another thing to keep in mind while you shop for reading lamps is how intense the bulb is. Some lamps use special bulbs that give off a great deal of heat, while others do not radiate hardly any heat at all. Test the bulbs before you purchase the lamps so that you will know what to expect. Reading lamps are usually used in close proximity to the book, which means that any extra heat coming from the bulb will be close enough to cause you some discomfort if you read for too long at a time.
