Ah, progress . Right around two years ago, we spotted a LED-filled light bulb that used "just" nine watts and cost a staggering $65. Now, we've got yet another option that sucks down even less power and costs nearly twice as much. C. Crane Company has been working on its so-called GeoBulb for a solid three years now, but at long last the device is shipping to affluent homeowners and headstrong Earth lovers. The bulb can provide as much light as a traditional 60W incandescent with just 7.5W, and it features a 30,000 hour (10 years) lifespan with typical usage. Now, the hard part: choosing between cool, soft and warm white.[Via Times-Standard
