Meet the NanoLight, a revolutionary light bulb that produces the same amount of light as a conventional incandescent 100-watt lamp, but that consumes just 12 watts.
According to its creators, this is the most efficient light bulb in the world; the average energy-saving bulb would consume – under the same conditions – 24 watts, while an LED requires 20 watts.
“The NanoLight is the first LED lamp of its kind, as it reduces energy consumption by nearly half [compared to today’s LED], says Jimmy Choo, one of the engineers who invented the new bulb. “Using only 12 watts of electricity produces 1600 units Lumen – or the equivalent of a 100 watt incandescent bulb.”
Chu and his colleagues promise 30,000 hours of illumination per bulb. Used four hours a day, a NanoLight could last up to 20 years at a cost of 22 euros for a 10-watt bulb or 34 euros for 12 watts.
Its designer says it limits as much wasted energy, like heat, as possible and emits a “brilliant neutral white light with a little warmth, to feel comfortable, as when exposed to the afternoon sun.” At the same time, it allows the lamp to operate at much lower temperatures than existing models, which reduces the risk of burning if touched by naked skin.
The team of three engineers, based in San Diego, looked for funding through crowd-funding website Kickstarter. The project not only reached its target of $20,000, it also convinced 2,170 users to donate over $100,000 a fortnight before bidding ended.
