Hundreds of American women have kept the lamps burning in lighthouses since Hannah Thomas tended Gurnet Point Light in Plymouth, Massachusetts, while her husband was away fighting in the War for Independence. Women Who Kept the Lights details the careers of 32 intrepid women who were official keepers of light stations on the Atlantic, Gulf, and Pacific Coasts, on Lake Champlain and the Great Lakes, staying at their posts for periods ranging from a few years to half a century. Most of these women served in the nineteenth century, when the keeper lit a number of lamps in the tower at dusk, replenished their fuel or replaced them at midnight, and every morning polished the lamps and lanterns to keep their lights shining brightly. Several of these stalwart women were commended for their courage in remaining at their posts through severe storms and hurricanes. A few went to the rescue of seamen when ships capsized or were wrecked. Their varied stories paint a multifaceted picture of a unique profession in our maritime history.

How electric light created new spaces that transformed the built environment and the perception of modern architecture. In this book, Sandy Isenstadt examines electric light as a form of architecture—as a new, uniquely modern kind of building material. Electric light was more than just a novel way of brightening a room or illuminating a streetscape; it brought with it new ways of perceiving and experiencing space itself. If modernity can be characterized by rapid, incessant change, and modernism as the creative response to such change, Isenstadt argues, then electricity—instantaneous, malleable, ubiquitous, evanescent—is modernity's medium. Isenstadt shows how the introduction of electric lighting at the end of the nineteenth century created new architectural spaces that altered and sometimes eclipsed previously existing spaces. He constructs an architectural history of these new spaces through five examples, ranging from the tangible miracle of the light switch to the immaterial and borderless gloom of the wartime blackout. He describes what it means when an ordinary person can play God by flipping a switch; when the roving cone of automobile headlights places driver and passenger at the vertex of a luminous cavity; when lighting in factories is seen to enhance productivity; when Times Square became an emblem of illuminated commercial speech; and when the absence of electric light in a blackout produced a new type of space. In this book, the first sustained examination of the spatial effects of electric lighting, Isenstadt reconceives modernism in architecture to account for the new perceptual conditions and visual habits that followed widespread electrification.

That is the question Bob Johnstone addresses in this follow-up to Brilliant!, his critically acclaimed book on the origins of the LED revolution. The answer is passionate individuals determined to make the world a better - and better-lit - place. The book tells the story of what has been called "one of the fastest technology shifts in human history." It is a shift that affects us all. Lighting accounts for up to twenty percent of the electricity we consume. LEDs use much less electricity than incandescent light bulbs, leading to huge reductions in our energy consumption, and helping to slow down climate change. But the LED revolution also encompasses light for better health and year-round crops, as well new, previously undreamed-of applications.
