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.

Myths about LED Lightingmyths busted led lighting × myths about led lighting × led lighting solutions × led lighting a house ×  led lighting bulbs × led lighting business × led lighting commercial × led lighting ceiling ×  led lighting design × led lighting home ×  led lighting systems × led lighting lamps ×  led lighting market

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.

      LED lights are absolutely important these days for households and commercial places. A place like stadium or auditorium needs proper lighting arrangements. If there is no proper lighting, you shall find that a lot of problems would occur in conducting sporting events or conferences or cultural programs on the stadium. Moreover, in this era of modernization, every stadium needs to be renovated so that they give more safety as well as comfort to the spectators. This will help increasing revenue collection of the stadium. This is why you need 400w LED flood light for the stadium. The advantage of using LED lights shall be discussed in the following section of this article.
      1. Environment Friendly Lighting Solution
      LED lights give environment friendliness, as it consumes lesser power or electricity. Basically, the mechanism of illumination of LED lights is completely different from the mechanism of traditional lighting systems. Florescent lights get heated up after certain time and they start consuming more and more power. Nevertheless, they release heat which can cause damages to the environment, contributing significant amount of heat to the global warming. To protect environment, it is better to adopt LED lights in place of the traditional lights. LED lights work more seamlessly and they prevent wastage of energy.
      2. High End Efficiency and Durability
      Since LED lights do not get heated up, some people think that they would not offer the best illumination. In reality, you shall get perfect illuminating effects from LED lights. These lights are made to serve users for a long time. Durability is a factor that makes LED lights so popular these days. Once installed, the LED lights can serve you for at least 20 years without any significant maintenance cost. On the other hand, orthodox fluorescent lights last around 5-10 years maximum.
      3. Colorful Lighting Solutions
      Arranging colorful LED lighting solution is quite a cost-effective thing. Stadiums often need to hold inaugural ceremonies for various sporting events or tournaments. For this purpose, colorful lighting will be required. That can be attained with the stylish as well as contemporary colorful LED lights. For colorful lighting, no additional cost is required. This is one of the biggest advantages of LED lighting.
      4. Heavy-duty Illumination
      With LED lighting solutions, you shall get heavy-duty illuminating solutions. You can opt for 1000 Watt LED light which shall give excellent lighting solution for the stadium without any hassles. Lights would not get warm even after being illuminated for long time. One can easily keep LED lights illuminated for 10 hours to 12 hours for the purpose of stadium flood lighting.
      5. Amazing Cost-effectiveness
      The best thing about LED lights is that they are highly cost-effective. You can save your money by opting for LED lighting solutions. Stadiums need heavy duty lighting solutions and thus the stadium authority has to pay high electricity consumption bills. With LED lights, initial investment would be high, but cost-effective on the long run can be attained. It will lower down power consumption and thus would make your monthly bills reasonable. LED lights would also last long without any maintenance requirements.

      Commercial LED Lighting Continues to be the Hot Trend
      Referring to the growth of the commercial market as a “trend” may be a misnomer. A “trend” often refers to something that is temporarily in style. The growth and adoption of LED lighting in commercial applications, however, is anything but temporary. Industry analysts expect commercial LED lighting to be the standard for all illumination systems for many years to come.

      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.

      115 Batman Street, Melbourne, Australia

      The Base Building solution for 115 Batman Street was designed to meet with the Green Star requirements of the project. The overall building design utilizes an integrated design ideology, taking significant advantage of the available daylight via both the high and extensive glazing.
      Window screening is used to provide amelioration of direct sunlight where necessary and the lighting control system that manages the lighting throughout the tenancy is linked to photo electric cells to dim the luminaires in relation to the available daylight. Motion sensors are also provided throughout to manage the lighting after hours by activating the lighting in areas of movement.
      The fitout orientated spaces including the main reception, meeting rooms were designed with large luminous grids of pendants while the staff breakout space was designed to be deliberately different with custom pendants that feature panoramic photo montages of the Royal Botanical Gardens.

      On October 13, 2016, Boston mayor, Martin J. Walsh unveiled the new LED-based architectural lighting of Boston City Hall. The lighting debut was during this year’s final Beer Garden on the Bricks event, themed “Light Bright Beer Garden.” The city intends the new LED lighting to highlight and enhance the building’s original design and increase public safety. The exterior lighting installation is one among several ongoing initiatives to highlight City Hall and City Hall Plaza and make them more inviting for residents.

      “I am proud that for the first time in its 48 year history, Boston City Hall is going to shine,” said Mayor Walsh. “This state of the art lighting system will help make City Hall the civic heart of our city by livening up the plaza, while making the area safer and connecting us to Faneuil Hall and Quincy Market. Bringing new light to City Hall is symbolic of a more responsive vision here at City Hall, one that is meant to be engaging, inspiring, and serve as a beacon of the city and our values.”
      New LED fixtures replaced the original Metal Halide exterior recessed lighting and the existing floodlights that illuminate the building’s lower levels and accentuate the entrances. The new fixtures cover the building in a warm white light, and they can produce a broad range of colors. Such color options can allow the City to light the building to acknowledge a variety of celebratory and public events.
      The mayor lit the building blue to recognize the police officers injured in East Boston, and as a further demonstration of its light changing capability, the mayor changed the color to pink in honor of Breast Cancer Awareness Month. The pink lights at city hall added to pink lighting of numerous buildings and landmarks around the city.
      The lighting highlights the original three-part design of City Hall. The lower levels house the public spaces of the building. The symbolic spaces including the middle sections hold the offices of the Mayor and the City Council, and the administrative spaces crown the building and house the administrative functions of government.
      According to the city, the new exterior lighting improves security lighting. The city says that the system allows for the floodlights and associated conduit added to the building over the years to be entirely removed.
      “By illuminating its iconic and bold form, City Hall’s interaction with Boston’s urban fabric may be reinvigorated,” said David Eisen FAIA, Boston Society of Architects/AIA (BSA) Vice President for Communications. “It’s a decisive step toward transforming one of the most internationally renowned buildings that make up our distinct architectural heritage.”
      The new fixtures are more energy efficient than the Metal Halide fixtures and the existing Flood Lights that they replace. The LED lighting is expected to save the city about 300,000 kWh of electricity annually compared to the replaced lights. The LED technology has a projected 20-year lifespan compared to the 4-year life of the metal halide lights that the LED system replaces. The City expects additional savings from the cost of maintenance and light replacement.
      Arcade lights have also been retrofitted with LED lighting to complement the new City Hall lighting. The same controller will be able to operate and coordinate both the arcade lights and the City Hall lights.
      “It is wonderful that the City is taking this opportunity to recreate its own home place – City Hall – as the keystone and central event in an ongoing pursuit of improved illumination for our city,” said Todd Lee, President of LIGHT Boston.
