”107-Year-Old Bulb States the Case for Leaving Lights On
The LA Times has written a sweet little feature about Livermore Fire House's lightbulb that has been burning for 107 years without a break—unless you count the 22 minutes it took to transport the bulb from Fire Department HQ to Station No. 6 in 1979. That's almost a million hours' worth of low-wattage, you know. Unofficial keeper of the bulb, retired firefighter Tom Bramell reckons its longevity is down to old-fashioned craftsmanship. "I believe the bulb has stayed alive so many years because the makers gave it a perfect seal, so no air gets inside the bulb to help disintegrate the carbon filament. This bulb operates in a vacuum and it doesn't burn hot. That's the secret." [LA Times via Boing Boing]Luxim's 250W Tic-Tac Sized Bulb Blows Away 400W LEDs
Luxim's new bulb may only be the size of a Tic-Tac, but this little bugger can crank out way more light at 250 watts than a traditional 400 watt LED. It can achieve this feat thanks to gas that is heated inside the bulb via electrical energy delivered to it by a "puck." As the gas turns to plasma, the bulb is illuminated. However, since most of the energy is not lost to heat, the light can reach a high level of brightness. In fact, it can produce up to 140 lumens per watt which is twice that of an LED and around 10 times that of a standard bulb. Impressive. Hit the link to see the light in action. [CNET and Luxim]
