Solid-state lighting advocates have been quick to promote the energy-efficient performance of LEDs, but have done so based more on intuition than reported findings. However, with the release of Osram Opto Semiconductors' November 2009 report, "Life Cycle Assessment of Illuminants: A Comparison of Light Bulbs, Compact Fluorescent Lamps and LED Lamps," there is now data to confirm that hunch. "Life Cycle Assessment of Illuminants" finds that, from "cradle to grave," LED lamps do indeed deliver on energy efficiency.
The report studied the production and use of LED lamps and evaluates their environmental impact throughout all of the stages of lifecycle analysis-raw material production, manufacturing and assembly, transport, use, and end of life-and compares these results with those of an incandescent lamp and a compact fluorescent lamp (CFL). For the specific purposes of the study, an 8W Parathom LED lamp was tested against a 40W incandescent general service lamp and an 8W CFL Dulux Superstar. All three of these lamps are part of Osram's available lamp offerings.
The study arrived at three main conclusions:
Under Eftekhar's leadership, Philips Lightolier has evolved to reflect the needs of its customers. By introducing new business services such as the Energy Services Group, and meaningful technological innovations that reflect the demand for energy efficient lighting, Eftekhar has continued to keep Lightolier at the forefront of professional lighting solutions. It is a challenge he now welcomes on a larger scale.
