Harness New LED Technologies in Your Facility

On October 19, we hosted an LED Seminar in St. Louis with presentations from Philips, Acuity Brands and Dialight on emerging lighting technologies and how they can improve your workplace. They each focused on different aspects of how upgrading to LED lighting can improve your workplace from improved light output to new connected systems.

State of the Lighting Industry from Philips

LEDs have made a huge impact on the lighting industry as they are extremely efficient, last far longer than traditional lighting and are capable of being dimmed. LEDs can last up to 100,000 hours depending on the type, which equates to about 25 years in an office.

Upgrading to LED lighting has its costs, as any upgrade does, but there are different upgrade strategies you can take:

  • Simply replacing traditional light sources with LEDs, like changing the lamp in a fixture, will save energy and be more sustainable, but does not provide a new look or feel. It is the least expensive and easiest transition to LED lighting.
  • Installing a retrofit kit to replace traditional panel lighting is a cost effective way to help provide a new look and feel to your lighting, in addition to standard LED benefits, without penetrating the ceiling.
  • Completely renovating your lighting solutions can be higher cost, but will provide a new look and functionality
  • Add Enhanced Controls. Adding control systems to your lighting allows you to adjust for natural daylight, whether or not the building is occupied, and lets you dim your lights, which can add 50-65% more energy savings in addition to the savings that simply come from switching your light sources.

Old technology is declining as LED improves. Issues with LED, such as glare, are being fixed, and LEDs can now come with integrated sensors and be connected into controlled lighting.

The Next Step, Lighting Controls from Acuity Brands

Switching out lamps help save energy, but the next step forward in energy reduction is controlled lighting. Connecting an entire building with an information system converged network creates an IoT building. IoT (The Internet of Things) delivers building services through one holistic IP system.

Lighting offers the ideal platform to enable the IoT in buildings:

  • Ubiquity — where there are people, there are lights
  • Continuous power for additional sensors and devices
  • Processing capability for edge computing
  • Energy savings from a lighting retrofit can help fund inclusion of IoT networking and sensors

A smart LED lighting system can provide the IoT framework to unify your lighting devices, building controls, management systems and networks.  New, smart lighting systems can provide enhanced, customer-focused services to maximize performance, reduce operational costs, create better visual environments and increase energy savings while enhancing user experiences.

Energy-efficient LED lighting is being transformed into a smart, connected platform for data-driven applications. As a result, companies can derive more value from their LED systems beyond energy-efficiency and high-quality lighting.  Smart applications can help enhance employee safety and security, improve parking management, leverage location analytics and propel operations to the next level.

Evaluation & Selection of LED Fixtures from Dialight

When choosing LED solutions for your workplace, you have to consider the safety standards your lighting must meet. Different standards apply to different environments, such as industrial verses a hazardous location.

The 2017 NEC NFPA70 Code Book is the standard for all such safety ratings. When it comes to lighting safety in general, heat must be considered – both how much heat the lighting emits and how much it can withstand from the environment.

Why upgrade to LED? Overwhelmingly the top reason is safety, followed by energy reduction, maintenance reduction and the reduction of overall operational costs. LED systems use less energy and last longer require less maintenance, making your workplace safer and more efficient.

Whether you are looking to make your workplace safer, or you are looking for an integrated control system, LEDs are your path ahead. If you have further questions, connect with your French Gerleman Account Manager for more information.

What You Need to Know About LEDs Before Your Next Project

How LED work

What is an LED and how does it work? 

A LED, or light emitting diode, is a semiconductor diode which has the ability to conduct an electrical current.  The diodes are formed by combining two different semiconductor materials to form a P-N (positive and negative) junction.  When current is applied, the negative moves to one side while the positive moves to the opposite.  Light is generated when the positive and negative charges recombine.

Lifespan

LEDs are unlike other traditional light sources in that they do not simply fail.  Instead, the LED’s light output slowly diminishes over time.  For example, L70 is the point in hours that the lumen output has depreciated to 70% of the initial lumen output.  L80 would be 80% of the initial lumen output.

Color temperature

The RGB white method and the phosphor white method are the two methods of producing white light with LEDs.  The RGB white method produces white light by combining the output from red, green and blue LEDs.  The phosphor white method produces white light in a single LED by combining a short-wavelength LED, such as blue or UV, and a yellow phosphor coating with one another.

LED

Key terms related to LEDs

  • Luminous Efficacy is the total luminous flux emitted by the light source divided by the lamp wattage and is expressed in lumens per watt (lm/w).
  • Lighting Fixture Efficiency is the ratio of the total lumens exiting the fixture to the total lumens produced by the light source.
  • Absolute Photometry is the evaluation of the performance of the combined LED fixture system. Prior to LEDs, luminaire performance was done using Relative Photometry which allowed fixtures and lamps to be evaluated separately.
  • Fixture Efficiency is the ratio of the total lumens exiting the fixture to the total lumens produced by the light source.
  • Delivered Lumens is the amount of a light source’s raw lumen output that reaches the intended illuminated area.

 

Now that you understand the LED technology and terminology a bit better, here are some considerations when evaluating your next lighting project:

 

  • DON’T assume that all LEDs are created equal because they are not! Be sure to do your research.
  • DO know who you are buying from. Use established manufacturers you can trust. Many early LED manufacturers are no longer in business.
  • DON’T assume that any fixture can be converted into a LED. New and old technology don’t always mix.
  • DO look for retrofit kits designed by the original manufacturer. Find out if retrofitting is the right choice.
  • DON’T use lumen output alone to evaluate light sources. Look at fixture efficacy to determine efficiency.
  • DO read the fine print and check the environmental temperature rating. While cold is rarely an issue for LEDs, heat can sometimes affect performance.
  • DON’T forget that equivalencies are not always equal. Again, always do your research.
  • DO pay attention to specific fixture listings and environmental concerns.
  • DON’T assume that just because a fixture looks good on paper that it will work for you. Ask for samples if they are available.
  • DO remember that technology is constantly evolving. Purchase extras if consistency is important to you.
  • DON’T assume that all measurements and calculations are the same. Entrust one solitary source to do all the measurements to ensure consistency.
  • DO remember to check your verticals. They are just as important as horizontals.
  • DON’T assume that colors will look the same from all fixtures.
  • DO pay attention to warranty information when choosing your LEDs.
  • DON’T stop upgrading your lighting system after switching to LEDs. Take full advantage of your LEDs by pairing them with the appropriate control strategy.
  • DO look into dimming, OCC and controls. They will increase the future value of your system.
  • DON’T settle for fixtures that aren’t designed to be serviced. Look for fixtures with replaceable parts.
  • DO include the additional maintenance savings of not having to change lamps and ballasts. Maintenance savings can be substantial.
