Are you sick of replacing the lightbulbs in your home multiple times a year? Well, the accepted planned obsolescence of lightbulbs may become a thing of the past. Jake Dyson, son of the inventor of the Dyson bagless vacuum cleaner and the Dyson Airblade hand-dryer, has developed a revolutionary new LED light that will last for 40 years (12 hours a day use).
The lamp unit, called Aerial, will retail for around £1,400 ($2,000) upon release in May. While the price may appear steep, if you calculate the false economy of buying conventional lightbulbs over a 40 year period, the Aerial wins out.
Dyson reveals that the secret behind the Aerial’s longevity – 180,000 hours of use, at full brightness – is a sophisticated temperature control system; its heat sinks keep the bulb at a moderate 55 degrees Celsius, or lower.
