A team at Cambridge University has produced a new light bulb design which costs a mere $2.85 USD and despite being the size of a penny, produces similar light to a fluorescent bulb while lasting over four times as long with a lifetime of 60 years.
The new design triples fluorescent bulb efficiency and is 12 times more efficient than incandescent designs. Also, it’s capable of instantaneous illumination, so the light lag associated with fluorescent bulbs may soon be a thing of the past. The new bulbs last 100,000 hours.
Cambridge’s design is already being prototyped and readied for production. RFMD in County Durham, England is the first manufacturer to jump at the opportunity to mass produce and ship the high-performing LED bulbs.
Professor Colin Humphreys, head of the team at Cambridge states, “This could well be the holy grail in terms of providing our lighting needs for the future. We are very close to achieving highly efficient, low-cost white LEDs. That won’t just be good news for the environment. It will also benefit consumers by cutting their electricity bills. It is our belief they will render current energy-efficiency bulbs redundant.”
