LED Emergency Sconce

For the electrical engineering community here in Nashville and middle Tennessee, this is a great emergency LED sconce.  I have ordered a sample for TLC Engineers who asked to see the fixture and can bring it for a demonstration to anyone else who would like to see it...  thank you.

• The emergency components are completely integral to the luminaire.
• Emergency lighting is provided for a 90 minute period in the event of power loss.
• The 121-EM is suitable for use in ambient temperature conditions from 40°C (104°F) maximum to -10°C (14°F) minimum.
• Available wattages include 35 watt and 50 watt.
• In order to provide speed to market, the 121-EM is based on 121 generation 1 technology. It is available with Wide Throw (WT), Forward Throw (FT) and Medium Throw (MT) optics. Note: luminaires with MT optics include a diffuse lens.
• 121-EM with FT and WT optics are provided with a clear glass lens for a similar outward appearance to the recently announced 121-Generation 2 sconce family.
• 121-EM sconces with MT optics are provided with a diffuse lens. For a similar outward appearance, simply specify the DL (diffuse lens) option on 121-Generation 2 luminaires for a closer match to the 121-EM with MT optics.

Each 121-EM wall sconce includes a combination indicator light and test switch located in the door frame center, near the wall.

Lighting Layout Calculator

HE Williams Lighting provides a lighting layout calculator on their website.  Here a link and screenshot of the recessed architectural section of lighting.  It is somewhat intuitive, but feel free to call me if you would like to discuss how to best utilize this tool.

Cree Lighting CR24 Troffer

The R9 Value for the 3000K Cree CR24 is 80 which adds to the industry leading CRI of +90.  A link to the energy study is below.

Energy.Gov Study

Per the DOE website,

"A good CRI score does not guarantee good color quality

One problem with the CRI is that it can give fairly high scores to sources that render some saturated object colors very poorly. An example below shows a case of a red-green-blue (RGB) white LED simulation optimized for highest luminous efficacy of radiation (LER, lm/W) at CRI R

a=80. This light would qualify for Energy Star and achieve high luminous efficacy2, but the actual color rendering is very poor. With R9 = -114, skin tones under this light look pale and unhealthy. "
