LED lighting systems, in addition to using less electricity, have the added advantage that they do not overheat like traditional incandescent bulbs. If you are going to use a particularly powerful LED bulb for long periods of time, you can install a heat sink as an extra measure, because as a general rule these luminaires maintain a stable temperature regardless of their power. This, as well as making them safer from possible accidents, makes R7S LED bulbs a very good source of light for reading lamps, as they will provide you with more than enough light to read or write without feeling hot.
