LEDs: The Promise & Performance |
LEDs (or Light Emitting Diodes) dominate private and public sector interest in today's environmentally conscious mindset. Long life, low energy consumption, and no mercury make LEDs the ultimate sustainable answer for our green economic initiatives. Governments invest billions in their development, and manufacturers race to bring their products to market before competitors. In the opinion of the U.S. Department of Energy (DOE) and many lighting industry veterans, the only thing which can slow LED momentum is LED marketing. If that last statement seems odd, please keep reading.
The DOE Commercially Available LED Product Evaluation and Reporting (CALiPER) program has tested 175 LED products to date (8/18/09) [1]. At one point, only 22% of the products tested (22 of 101) lived up to manufacturers' performance claims [2]. In other words, 78% of the products tested failed to (for example) provide as much light or last as long as manufacturers' advertising suggested.
At 1000Bulbs.com, we want to ensure—to the best of our ability—your satisfaction with the LED products you purchase. Therefore, we have asked each of our 44 current or potential vendors to reply to our technical 1000Bulbs.com LED Vendor Questions. If you are considering an LED product on the 1000Bulbs.com website and would like to review the manufacturer's responses to these questions, please let me know. Assuming we have received a response, I will be happy to forward their response to you and answer any supporting questions you may have. We have also prepared a set of 1000Bulbs.com LED Customer Questions which you may wish to consider before purchasing an LED product from 1000Bulbs.com or any other source. Once again, I will be happy to answer any supporting questions you may have.
LEDs are some of the most sought after products on the 1000Bulbs.com website. It's our hope that these precautionary notes will add to their intelligent use. We are committed to our customers' satisfaction. Please let us know if we can help in any other way.
