Study: LED lifecycle assessment
A study on the lifecycle assessment of LED lamps shows the latest generation of lamps achieves a very high score for environmental friendliness.
A study on the lifecycle assessment (LCA) of LED lamps by OSRAM shows the latest generation of lamps achieves a very high score for environmental friendliness. This study involved a close look at their entire lifecycle--how much energy and raw materials the lamp consumes in terms of production, use, and disposal and the environmental impact involved in the process. The result was that today's LED lamps achieve the LCA values of compact fluorescent lights and are far superior to conventional incandescent lamps.
LEDs are among the most energy-efficient light sources available on the market. LED lamps are already today more than five times more efficient than incandescent lamps and future technical achievements offer additional potential for the coming years.
At present, artificial lighting accounts for around 19% of global electricity consumption--that corresponds to 2.4% of worldwide primary energy consumption.
An OSRAM study monitored the lifecycle of an LED and an LED lamp. Its outcome made it clear--LED lamps need less than 2% of their energy consumption for their manufacture-over 98% are used for their task: illuminating the world.

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.
