The Grand Hall Ballroom at Historic Union Station




Listed in the National Register of Historic Places, the Crowne Plaza at Historic Union Station is housed with America’s first “union station.” Union Station’s majestic red-brick and granite “headhouse,” built in 1888, is recognized as one of the finest Romanesque Revival-styled structures in America. – Crowne Plaza


Down the center ceiling of the Grand Hall Ballroom, there is a 120′ long by 35′ wide, stained glass window barrel ceiling, which is illuminated only by artificial light from above.  Through special passageways on the south stairwell, lies a catwalk on either side of the ceiling running parallel to the massive artistic feature.  Lining both sides of this 130+ year old structure were a total of (30) 400w Metal Halide Flood Lights.  Both hard to reach physically and with a fair degree of danger (not only to the electrician, but to the stained glass structure). Challenge: to work with the property’s electrical contractor to illuminate the stained glass feature appropriately to reveal it’s true beauty, while saving energy, and providing a controllable light output for the various special events that the site holds on a regular basis.


To maximize light coverage with constraints provided, we ended up specifying an area light fixture from Cooper Lighting‘s McGraw-Edison line-up, The Galleon LED Area Light, which offered best in class optics, allowing us to reduce the numbers of fixtures needed from (30) to (10), to direct light both efficiently and reduce the overall energy footprint.  Additional measures were taken with selecting an 80 CRI index and utilizing a 3000K color temperature to maximize brilliance of colors used in the stained glass.  A simple 0-10V dimming option allows the property to adjust the light output for special events, which also further reduces the overall energy consumption of the lighting.
