Are LEDs the way of the future?
Some believe the light-emitting diodes will replace incandescent and CFL bulbs.
The nation’s Big Three of lighting—General Electric, Osram Sylvania, and Royal Philips Electronics—are embracing a new era of more efficient technologies, like halogen, compact fluorescent, and solid-state devices. Encouraged by legislation and the rising cost of energy, as well as concerns about greenhouse gases, consumers are swapping out incandescent bulbs.
LED bulbs , with their brighter light and longer life, have already replaced standard bulbs in many of the nation’s traffic lights. Indeed, the red, green, and yellow signals are—aside from the tiny blinking red light on a DVD player, a cellphone, or another electronic device—probably the most familiar application of the technology.
On the other hand, energy efficiency and flexible lighting applications have long been the promise of organic light emitting diodes (OLEDs). The technology hasn't lived up to its promise, however, because in typical OLEDs, only 20% of the light generated is released from the device. That means that most light is trapped inside the bulb, making it highly inefficient.

Annual Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
