Building Products & Maintenance LED Lighting – The Basics Behind the Pitch A look at the numerous benefits & potential drawbacks of light-emitting diodes By Brennan Booms Enlighten Y ou’ve surely heard about or had first-hand experience with LED lighting by now – and you’re likely familiar with the marketing/advertising language commonly thrown around in support of the tech-nology. “It saves energy” and “lasts a very long-time” are two of the more common selling points. in a technology project of 20%. Government organizations may tolerate a lower return. Typically, a property whose lights run more than 25 hours weekly will clear that hurdle. Many commercial sites operate most of their lights for approxi-mately 40 hours a week. However, sites may run their lights for 80 hours per week (two shifts) or more. Add in a little bit of sav-ings from reduced maintenance time and most buildings will see between a 30% and 100% ROI for an investment in LED scaling with the number of weekly hours the building runs. Like any newer technology, LED is not without its stumbling points: compatibility with incumbent fix-tures, narrow light spread and pre-mature failure are a few possible drawbacks. All of these can be easily avoided if someone involved in the project has a good grasp of lighting design, a good under-standing of LED technology, and a good knowledge of repu-table manufacturers. Likewise, with any technol-ogy, finding someone expert in the matter can help you to better understand and quantify how various options apply to your application as well help you to manage to an opti-mal conclusion.

Energy savings An LED light will use between 30% and 80% less power than an equivalent older-technology light (e.g. fluorescent, halogen, incandes-cent, etc.). However, this is not the final conclusion on energy savings. Energy is a function of power con sumed over time. Said a not her way, a piece of equipment that draws a lot of power but over a short period of time will not consume a lot of energy. Therefore, converting to an LED lighting system will translate into significant electricity sav-ings only if the building’s lights run for a non-trivial amount of time each week. lives and longest warrantied periods of any lighting technology. Increased light quality Simply swapping out an old light for an LED light does not guarantee better lighting. However, upgrading a lighting system provides the oppor-Maintenance savings Summarizing the benefits Most businesses look for a mini-mum return on investment (ROI) 74 Photo courtesy of Enlighten Third-party groups test large samples of lights and create a rating in total number of hours describing when the majority of lights will reach the end of their useful life. A warranty is provided by the manufacturer (as opposed to a third party) and describes the number of years after purchase a manufacturer will replace a prematurely expired light. The warrantied period is usually shorter than the rated life. LED receives its “long-life” status from the fact that its lights come with the longest rated Upgrading a lighting system provides the opportunity for better illumination, given that someone involved has a good understanding of lighting metrics, light source characteristics and space illumination projections. tunity for better illumination, given that someone involved has a good understanding of lighting metrics, light source characteristics and space illumi-nation projections.
