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.


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.


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.

Product Spotlight: Hubbell Tamper-Resistant Receptacles

When it comes to common plugs on small devices like electronics chargers, lamps, appliances and extension cords, they often have flexible blades with sharp edges and burrs that catch in conventional temper resistant (TR) outlets. This can cause damage to the devices and/or safety concerns. Hubbell’s patented technology resolves this issue! Their receptacles are tamper-resistant, not plug resistant.

Hubbell heard concerns from customers when it came to their tamper-resistant receptacles and this drove their product development team to engineer a better way. The result? Hubbell created a patented cam action mechanism. When a plug is inserted into a Hubbell tamper-resistant receptacle, the cam will slide the insulating barrier out of the way, a rotating action that eliminates friction creating a more reliable and smoother insertion. The Hubbell Cam Action Technology makes inserting a plug as easy as plugging into a standard receptacle. This new design has been incorporated into the Hubbell Industrial, Hospital, Commercial and Residential receptacles.

Approximately 2,400 children suffer severe shock and burns from sticking objects into unprotected receptacles, according to the NFPA. The 2014 NEC Code requires that tamper-resistant receptacles to be installed in:

  • Hospitals and healthcare facilitieshubbell usage
  • Child care facilities
  • Hotels/hospitality
  • Assisted-living facilities
  • Schools and higher education housing
  • New and remodeled residences


We are seeing a huge surge in TR receptacles in libraries, lobbies, neo-natal wings, waiting rooms, grade schools, pediatrics and manufacturing plants, just to name a few. The safety and ease of these Hubbell tamper-resistant devices makes them perfect for these applications.

You can view the full line of tamper-resistant receptacles from Hubbell HERE. Have any questions or need help selecting what TR receptacle will work best for your location? Give your French Gerleman Account Manager a call or contact us.

Product Spotlight: APC Server Room Cooling Solutions

One French Gerleman customer was struggling with their server room cooling challenge and came to us for some product and service options. Like many clients we work with, they didn’t have an abundance of space in their server room and were looking for alternative, space-saving ideas. In this video, Joe Dody, Manager of the Datacom Division, and Jason Stockmann, VP of Information Technology, present this client’s challenge and explain how with APC’s Server Room Cooling Solutions, they were able to save the day.

This client’s facility is underground and the server room is located in a converted small office that didn’t allow for expansion. They were unable to install an external condensing unit to provide cooling to the server room. That’s where we came in to get creative, and offer them an efficient and cost effective APC option.

APC offers a unique self-contained solution for data centers. Unlike other units, it has a built in condensing unit that used the plenum air space above the data center to expel hot air, and draw in cool air. This is ideal for smaller spaces or when looking for alternatives to having your condensing unit outside of the building.

You benefit from ease of deployment when working with French Gerleman and APC. There is one part number, and APC does the configuration, schedules the install and start-up, and you are ready to go.

From a budget standpoint this client looked into three options. The first one would be to install an external condensing unit. This would have been three times the cost of the APC self-contained cooling solution. The second option was to look into what they could do with their existing HVAC system, but in their circumstance, their existing HVAC was not adequate enough to produce the cooling required. The APC solution was not only the most cost effective option, but the most space saving option.

In the end, the client was happy to have a solution to their cooling dilemma. Does your business have a similar problem? We would love to help you create a solution that works for your company. Give us a call at 800-333-3122 and ask to speak with a representative in our Datacom Division to discuss your options.
