Lighting Retrofit vs. Lighting Redesign The revolution in industrial and commercial lighting is shepherding in a host of new LED lighting systems that are replacing traditional metal halide and high pressure sodium fixtures. As more organizations look to make this transition, their first question is whether they should retrofit existing lighting systems to utilize LED fixtures and control systems, or move entirely to a new redesign of their entire lighting configuration. As with many other facilities-related issues, this decision will be a function of personal preferences, the facility itself, and budgetary considerations. LED Lighting Retrofit If you are working with a limited budget and the facility does not have unique lighting needs, a retrofit may be adequate. Existing lamps can simply be replaced with LED lamps and self-contained drivers. The end result will be equivalent or better illumination with an immediate reduction in utility costs, but maintenance costs will likely be higher than with a full or partial redesign. LED lamps can be more directional than traditional bulbs, and replacing existing lamps will not solve light distribution issues or elimination of any shadows that an existing design had created. LED Lighting Redesign The next step up from just replacing lamps is changing all of the existing fixtures with LED-specific luminaires. New LED lamps and fixtures will likely generate greater illumination than prior-generation lamps, and this option might produce an environment that is overlit. Moreover, replacing the fixtures will not readily facilitate the addition of advanced controls for the LED lights, such as dimming and custom adjustments of individual fixtures. LED Lighting Retrofit vs. LED Lighting Redesign A complete lighting system redesign will impose the highest upfront cost on an organization, but that cost can be more quickly recovered through utility and maintenance cost savings with a redesign than with a simpler retrofit. Design engineers will analyze the space that need to be illuminated and will sketch out a customized plan that includes a blend of different LED fixtures to achieve optimum lighting in the facility. LED’s are available in a variety of light dispersion patterns that can be mixed and matched to uniformly light a facility with a minimum of dark spots and shadows. The engineer can also incorporate advanced control systems into a new LED lighting design that allows a facilities operator to selectively dim or adjust individual fixtures to alter facility lighting to coincide with particular or changing uses of the facility. LED lighting technology has advanced rapidly over the past ten years. Decisions about retrofitting or redesigning a lighting system should be based on the most current available information. Manufacturers and designers of LED lighting systems have also gained considerable experience in that time with helping their clients to make the best lighting choices that fit their needs and that do not go over budget. That experience extends to adapting specific color temperature and color rendering indices (CRI) into new lighting systems that can improve employee morale and performance with lighting that better matches natural sunlight throughout the day.

8 SIGNS YOU’RE READY TO INVEST IN LED LIGHTING You will likely find ample justification to support the business case for your organization’s transition to LED lighting. In most cases, that justification will be derived from your organization’s experience with its current legacy lighting system. That experience will provide at least eight signs that you are ready for LED lighting. You have lost control over your utility costs. Traditional metal halide or high pressure sodium light fixtures might have been state-of-the-art when they were installed, but they have never been particularly efficient. Much of the power they consume is dissipated as excess heat. As electricity costs have gone up, your organization has spent more and more money that is wasted by these traditional fixtures. More efficient LED lighting will reverse this pattern. Your lighting maintenance team is overworked. Metal halide or high-pressure sodium bulbs need to be replaced, on average, every two years. If the entire lighting system fails, your maintenance team can take an hour or two to bring it back to full power. Broken or damaged fixtures can shut down a complete bank of lighting, interrupting your company’s operations. These problems can all be reduced or eliminated with LED lighting systems. Your company has adopted environmental initiatives. LED lighting places lower loads on electrical power generation plants, thus reducing carbon emissions. LED lamps themselves contain no hazardous materials that might contaminate landfills when they are eventually replaced and discarded. Employee productivity is down. Studies have revealed a close connection between adequate lighting and employee productivity. LED lighting pushes the advantage of good lighting even further. Certain wavelengths of light can improve mood and increase productivity. LED’s can be adjusted to generate light in these wavelength, leading to potential employee productivity improvements. Workplace mishaps are increasing. Many workplace accidents are the result of poor visibility and lighting systems that create shadows and dark spots. Employees experience fatigue and eyestrain in poorly-lit environments, which contributes to more accidents in those environments. LED lighting can be configured to eliminate those dark spots and to generate uniform illumination across an entire workspace. Moreover, LED lighting can be tuned to better replicate natural sunlight, giving employees the best possible lighting to avoid mishaps. Your business is expanding. If you are building new facilities, it makes little sense to install old technology in those facilities. LED designers and engineers can develop a custom LED lighting solution for new construction that optimizes the lighting environment with fixtures and systems that give facilities managers unprecedented control over illumination. Your operations are conducted under extreme conditions. Large temperature swings, different forms of precipitation, heavy machinery, and round-the-clock movement can all put strains on a lighting system. Next-generation LED lighting is engineered to withstand these strains and to continue in full operation regardless of the extremes. You need to power up lighting systems quickly. Traditional lighting can take up to 30 minutes before coming to full illumination. LED lighting eliminates that lag and comes to full illumination almost immediately after being powered up.

The 5 Biggest Myths in LED Lighting In their early stages, most new technologies are the subjects of myths that are either exaggerations or inaccuracies, if they are not altogether incorrect. LED lighting has been the subject of many myths since the first installations of LED systems appeared several years ago. Many of those myths denigrated LED lighting on the basis of cost and performance. As LED technology has improved, early-stage problems have disappeared but the myths have remained. Rather than falling prey to those myths, organizations that are considering LED lighting for their own operations should base their decisions on objective facts about modern LED lighting systems. Myth: LED lighting is expensive. Fact: As with many new technologies, the first generations of LED lighting systems were costlier than traditional metal halide or high-pressure sodium alternatives. Upfront acquisition and installation costs have since fallen dramatically and LED retrofits or new installations can now be completed at competitive price points to those traditional systems. Moreover, LED lighting generates the same or better illumination with substantially lower power input. Upfront system costs are usually recovered very quickly from utility cost savings alone. Myth: Light from LED bulbs is too harsh or bright. Fact: New LED bulbs and control systems give operators much more flexibility to alter the color temperature and color coordinated index (“CCI”) of LED illumination to tone down the perceived harshness that might have plagued earlier LED systems. Modern fixtures and lenses also help to disperse lighting and to reduce glare from brighter bulbs. Myth: All LED bulbs are identical. Fact: LED bulbs include more complex technology than incandescent or fluorescent fixtures. Quality LED manufacturers push that technology to produce better and longer-lasting products that incorporate features such as advanced thermal control and more stable electronics. Some LED systems might cost less than others, but those lower-cost systems might not have the newest technology that creates improved lighting performance. Myth: LED lamps never need to be replaced. Fact: LED’s last substantially longer than traditional lighting fixtures, but the will need to be replaced at some point. On average, LED bulbs will perform above a minimum illumination level for 50,000 hours. Many continue to generate light beyond this average lifespan, but their total light output will be lower than when they were first brought into service. Facilities that install LED lighting systems will continue to need to plan for maintenance and replacement, but those needs will be substantially reduced in comparison to traditional lighting. Myth: LED lighting is bad for your health. Fact: Doctors’ groups did criticize early generations of LED light that had high concentrations of blue-wavelength lighting. Lighting in that wavelength tends to keep people alert and to interfere with circadian rhythms and sleep patterns. Newer LED systems have controls that allow operators to reduce blue wavelengths in favor of more calming orange or yellow lighting. Therefore the early criticisms are no longer as valid. Myth: LEDs have sub-par color rendering index properties Fact: Incandescents have a perfect color rendering index (CRI) of 100, so when alternative energy-saving lighting solutions like fluorescents came to the market, people were disappointed in the quality of the light. And rightly so. Many compact fluorescents have a low CRI of 50. Most LEDs have a solid CRI of 80, with High CRI options available when color rendering is very important (like in restaurants, retail stores, galleries, etc). Our LED MR16, for example, has an incredible High CRI option of 95, so colors appear as vibrant to the eye as under broad daylight. Source: specgradeled

LED LIGHTING MAINTENANCE AND UPKEEP When commercial and industrial LED lighting systems were first introduced, some proponents of those systems claimed that they were maintenance-free with lifespan expectations in excess of 50,000 hours. LED systems do have fewer maintenance obligations than the metal halide and high-pressure sodium systems that they are replacing, but even minor maintenance will extend the life of an LED system and improve the economics of an organization’s decision to transition to LED’s. In addition, a handful of companies have crafted LED lights with advanced thermal management that reduces their degradation due to heat buildup, and simpler LED designs that allow for repair and replacement of LED lamps and fixtures with few or no tools. LED Lighting Maintenance LED lamps generate light through solid state electronics that are controlled by embedded drivers in the lamps and fixtures themselves. The actual components that generate light are less likely to degrade than the drivers, which can experience performance degradation due to heat buildup and thermal overload. A few of the pioneering manufacturers of LED lighting systems, including SpecGrade LED, have designed patented thermal management systems that more effectively remove heat from the lamps and fixtures. Heat transfer will be improved if the lamps and fixtures are kept free from dust and debris, and occasional cleaning of LED fixtures can lead to longer performance. LED maintenance costs are typically divided between components and labor. Component costs will generally not vary, but labor costs can increase dramatically if a lighting system is complex and more time is required to access and repair fixtures, or if those repairs need to be done at off times when a facility’s regular operations have subsided. Next-generation LED fixtures and systems incorporate designs that facilitate quicker and easier repairs that can be completed with few or no tools. Modular LED systems also allow repairs and replacements of single fixtures without affecting other fixtures in a lighting array. As LED control systems become more advanced, manufacturers will likely include features such as remote wireless control and monitoring. A facilities manager can then coordinate and control lighting in several locations from a single wireless internet-connected device. Organizations that are considering an LED retrofit or an installation of an LED system into a new facility should plan for updates and upgrades to those systems that wireless control and other future innovations. Adopting a more flexible LED system now will make upgrades simpler and less expensive in the future. Organizations can plan for regular periodic maintenance of an LED system, or they can adopt a more reactive program that calls for maintenance as a response to performance issues. If, for example, a facility’s electrical utility costs begin to increase, or employees note that LED illumination is decreasing, the organization can then implement maintenance procedures in response to those observations. In all cases, LED maintenance and upkeep obligations add to overhead costs that every organization seeks to control. Those costs are already lower for LED lighting systems, but they can be reduced even further if an organization selects an LED system that includes advanced thermal management systems and that makes repairs and replacements as simple as is possible.
