LED Lighting: A Primer to Lighting the Future

(O’Reilly,
paperback, Kindle)

Sal Cangeloso of Geek.com and ExtremeTech.com wants to warm you up to some really cool lighting: light-emitting diode (LED) bulbs.

His new book, LED Lighting: A Primer to Lighting the Future, encourages readers to start using more LEDs and let loose of the incandescent bulb’s 130-year-old technology, as well as the curly, tricky-to-recycle compact fluorescent light (CFL) bulbs that last longest when they are not turned off and on and off and on and.…

Lighting and lighting choices are not actually simple topics, and Cangeloso packs plenty of information, both practical and technical, into his helpful 58-page book. He includes a couple of simple, do-it-yourself experiments involving small LED lamps, resistors and batteries, as well.

LED Lighting delves into matters such as color quality, power consumption comparisons, and prices, as well as the sometimes “off-putting” fact that LED bulbs often look like yellow bug lamps, even though they produce white light. The author also explains why highly efficient LED bulbs have built-in heat sinks, while other types of light bulbs do not. “The main reason is that LEDs don’t give off heat in the form of infrared radiation. This means cooling must be handled through other means, such as conduction through a heat sink.”

LED bulbs also don’t give off ultraviolet (UV) light. So that’s one more practical reason to consider using them. As Cangeloso notes: “LED bulbs don’t attract insects, which are drawn to UV light.”
