This course is temporarily offline for review. Please check back again soon for availability to enroll or contact FEMP_Training@ee.doe.gov for more information.

This course will first provide an introduction to key lighting and energy terms. It is important for
users to understand lighting terms:

  • The amount of light output by the device;
  • The efficacy of the device (conversion of power into light);
  • Color metrics and how they might affect certain lighting decisions; and
  • Glare which is the ratio of foreground brightness to background brightness. Glare is a driving choice in certain lighting conditions.

The bulk of the course will focus on the options including TLEDs, retrofit kits, and new fixtures. A review of the three types of TLEDs, installation features and concerns, and energy savings potential of TLEDs will be discussed. Retrofit kit options and installation details will reviewed.


Michael Myer, Lighting Engineer at Pacific Northwest National Laboratory.  

Mr. Myer earned a B.A. from Arizona State University and an M.S. in Lighting from Rensselaer Polytechnic Institute. Mr. Myer is a lighting engineer with considerable experience in architectural lighting design and knowledge about lighting, specializing in sustainable lighting design, controls, and new technologies. He brings hands-on skills to the project, previously working in lighting design for Naomi Miller Lighting Design and Hayden McKay Lighting Design.

Learning Objectives

Below, are the objectives and activities the learner will be able to accomplish/master as a result of participation in the training program:

  • Users will understand key metrics related to lighting in order to better evaluate different options. For example, users will learn about lumens (basic unit of light) and how this value factors into glare as well as illuminance (the amount of light falling in space). Users will understand that lumen selection is key to many choices. Users will also learn about color metrics and how these metrics ultimately drive choices;
  • Users will understand lighting energy use. First how much it uses, different methods to evaluate it, and how to effectively manage it;
  • The course will provide the differences between 3 lighting technologies: tubular LEDs, retrofit kits, and new fixtures. Users will be learn about installation time, installation challenges, and the benefits of each option; and
  • Lighting controls will be presented to users. Users will learn about basic lighting controls such as occupancy sensors and daylight sensors, but also learn about different control protocols such as Wi-Fi, Zigbee, Bluetooth, and Power Over Ethernet (PoE).
  • Attendees will learn federal requirements and resources available.
