We all know how energy efficient LEDs are, as they sometimes boast nearly 80-90 percent energy savings when compared with conventional bulbs. However, the new question: Is the LED’s energy efficiency worth its production cost? In other words, is it still more efficient overall — from production to disposal — to use an LED lamp? According to OSRAM Opto Semiconductors, the answer is “Yes.”
OSRAM recently conducted a new LED technology study based on Life Cycle Assessment (LCA) which revealed just how environmentally-friendly LED lamps really are. Basically, an LCA quantifies how much energy and raw materials a lamp consumes in terms of production, use and disposal, and the environmental impact involved in the process. To be expected, LED lamps achieved the LCA values of compact fluorescent lights and were far superior to conventional incandescent lamps.
The study used a single, 25,000-hour LED bulb as a standard reference point, and, in order for an accurate comparison, this meant 25,000 hours worth of incandescent and compact fluorescent bulbs were needed (approximately 25 and 2.5, respectively). According to the study’s initial findings, LEDs used less than 2 percent of their overall energy consumption for production, deeming them energy efficient and environmentally-friendly all the way around.
According to OSRAM, the study is currently being peer reviewed and is scheduled to be published in October.
