To find the best LED book light, you should consider what you want from a light and the types of settings in which you are likely to use it. You should consider how any book light will connect or remain in use to illuminate a book, as there are a number of different types of lights that can be used with many different ways of affixing such lights. It can also be helpful to consider the power source for an LED book light, as some run on different kinds of batteries, while others plug into an electric outlet or run on solar power.
A light emitting diode (LED) is a type of illumination device similar to other light bulbs, but with certain advantages over other forms of illumination. LEDs can be quite small while still providing a good deal of light, and they typically do not produce as much heat as some other types of bulbs. As you consider the best LED book light for your needs, you should think about how bright you want your book light to be. Brightness is typically measured in lumens, and anything over 100 lumens may be too bright for use in a dark room where others are sleeping.
You should also look at the different ways an LED book light can be connected to a book or otherwise used. Some models use clips that allow the light to attach directly to a book, and when paired with an adjustable neck for the lamp this will allow you to easily adjust the area of illumination. You might also consider an alternative to a standard LED book light such as a head lamp that is often used in construction work. This light is on a headband that can be worn around the top of the head, allowing “hands free” use while illuminating the area you are looking at.
There are also different power sources that can be used with an LED book light, and you should find the right type of power supply for your needs. If you plan on using your light while camping or traveling, you should consider a light that runs on batteries, preferably ones that are easy to find. You might also look for one that folds or collapses for easy transport. You can also choose an LED book light that plugs into a wall socket, if you are concerned about excessive battery usage. There are also book lights that are rechargeable and run on solar power, allowing them to be recharged during the day while not in use.
