LED Lighting: A Primer to Lighting the Future by Sal Cangeloso. Maker Press/O’Reilly Media, Sebastopol, CA. makerpress.com. 59 pages. ISBN 978-1-449-33476-5.
Light-emitting diode (LED) lighting has become all the rage. While the technology is still more expensive than incandescent or fluorescent lighting, there are many applications where the benefits outweigh the cost.
What are those applications? Well, that’s the question this book will help you answer. Not only does it explain LED technology in a straightforward way, it offers some help in making a decision on whether or not to go with LED lighting.
This help comes in Chapter 8, “Do LEDs Make Sense Today?” As the book explains, there are three things to consider when contemplating the switch to LED lighting:
- initial cost,
- power savings, and
- replacement costs.
By replacement costs, the author means not the cost of a replacement bulb, but the labor cost involved in replacing it. For example, if a bulb is located in an inaccessible place such as a fixture high up on a wall or ceiling, the labor cost could be considerable. Using LED lighting reduces these costs because you have to replace them very infrequently.
According to the author, the future is bright (pun intended) for LED lighting. As companies develop the technology, costs will come down, making them the right choice for more lighting applications. “It’s just a matter of time,” he says, “until the light-emitting diode is the tool by which we illuminate the world around us.”
