From In the Kingdom of Ice: The Grand and Terrible Polar Voyage of the USS Jeannette, by Hampton Sides (Knopf Doubleday, 2014), Kindle pp. 170-173:
Collins was befuddled. It was true that he had never tested the lamps in San Francisco, but in Menlo Park he had seen with his own eyes how brilliantly they worked, illuminating Edison’s lab with a “light greater than three thousand candles.” Why weren’t they working now? De Long put Melville on the problem. After taking Edison’s device apart, the engineer concluded that it must have gotten doused during the turbulent crossing of the Bering Sea. He dried out the apparatus, then tried uncoiling all its wires and reinsulating them, but it was no use: Not even Melville, the Jeannette’s crafty Vulcan, could get the thing to work.
A few days later, Dr. Ambler told De Long of a curious dream he’d had about Edison’s lamps. In the dream, Sir John Franklin, the long-lost British explorer, had come aboard the Jeannette for a tour. Dr. Ambler led Franklin all over the ship and told him excitedly about Edison’s electric lights, an invention that, of course, wasn’t even dreamed about in Franklin’s day. But Franklin bluntly interrupted him. “Your electric machine,” he said, “is not worth a damn.”
“I begin to fear that Franklin is right,” De Long wrote. “Edison’s light is irretrievably worthless. Time enough has been lost in trying to make this machine of use.” Perhaps it was Edison’s fault, but De Long placed much of the blame on Collins. In any case, the lamps had “gone ‘where the woodbine twineth,’ ” as De Long put it—which was to say, into the junk pile of oblivion. Disgusted, he told Collins to box up the lamps and stow them in the hold. Collins was despondent, his mood as black as the unlit Arctic.
And so the days grew shorter and colder—and the natural light ever more feeble. The sun slowly slipped from the polar skies. On November 16, it left altogether and would not return for several months. Spermaceti candles and oil lanterns would have to suffice. So much for Thomas Alva Edison and his company’s pledge about “lighting the North Pole.”
For the next seventy-one days, the Jeannette would be cloaked in darkness.

On the night of October 21, 1879, Edison was experimenting with a filament made from carbonized sewing thread. A vacuum bulb fitted with the new filament was arranged on a small platform in the lab. When power was supplied, the lamp burned, unflickering, for an hour, then two hours, then three. Edison, having grown tired of the experiment after slightly more than forty hours of steady light, ramped up the power until the filament finally sizzled and burned out.
“The electric light is perfected,” Edison crowed to the New York Times. Although this wasn’t quite true, his incandescent bulb was now well on its way to reality—and already it represented a quantum leap over the arc lamp system he had sold to De Long. His company had also made significant improvements in the reliability of its dynamos: The model Edison provided for the Jeannette expedition had caused endless problems for his customers, but after he overhauled the design, subsequent generations of his dynamo had proved admirably dependable.
By November, having applied for a patent for his incandescent lamp, Edison tried out a new filament made of carbonized bamboo. It burned true for more than twelve hundred hours. By December Edison was making public demonstrations and taking his first commercial orders. “We will make electricity so cheap,” he said, “that only the rich will burn candles.”
