This course is registered with AIA CES for continuing professional education. As such, it does not include content that may be deemed or construed to be an approval or endorsement by the AIA of any material of construction or any method or manner of handling, using, distributing, or dealing in any material or product. ___________________________________________ Questions related to specific materials, methods, and services will be addressed at the conclusion of this presentation.
- 3. Sponsors It is predicted that by 2016 LED lighting will be approximately 50% of the residential lighting marketplace. This rapid adoption means that LEDs will soon become the primary lighting source in single-family and multi-family construction. This course will focus on the LED and Solid State Lighting technologies and design concepts that are leading the way in the re-shaping of residential lighting design. The efficiency, small scale and ubiquity of these new technologies are providing designers with opportunities to integrate LED lighting into innovative residential lighting design concepts using multiple LED lighting layers. The course also will cover updates on the latest and most innovative LED product introductions for residential applications.

- 56. LED Facts
- 57. Lumen The most common measure of light output (or luminous flux) is the lumen. Light Source Lumens 60 Watt Incandescent 820 15 Watt CFL 950 8 Watt LED 810
- 59. Incandescent and LED comparison
- 60. Efficacy Light Source Lumens Lm/W 60 Watt Incandescent 820 14 15 Watt CFL 950 63 8 Watt LED 810 101 The light output emitted by a light source divided by the nominal light source wattage and expressed in lumens per watt (lm/W).

- 66. The color rendering index (CRI) scale is used to compare the effect of a light source on the color appearance of its surroundings. A scale of 0 to 100 defines the CRI. A higher CRI means better color rendering, or less color shift. Color Rendering Index (CRI) · 97 Lumens per Watt · CRI 90+ · 2700K, 3000K, 3500K, 4000K
