Philips has been hitting us with some out-there lighting concepts
lately, but the company's Master LED light bulb is actually already on sale in Europe and is set to brighten up Stateside lives around July. The 40W-equivalent bulbs should run between $50 and $70, and expected lifetime is set at 45,000 hours -- just slightly more than a CFL's 10,000 or a standard bulb's 750 hours. The Master is certainly a damn sight nicer looking than the other mutant LED bulbs
we've seen, but we'll see if consumers are ready to jump on another more-expensive-upfront lighting tech so soon after CFLs have hit the mainstream.
