Several major improvements have been made to the 21-story Union Plaza Building in Little Rock, but none have been as dramatic as its new exterior lighting system, which has transformed the nighttime skyline in Arkansas’ capitol city.

Now at night the Union Plaza Building is highlighted by Dyna Drum HO and Dyna Flood QA luminaires from Acclaim Lighting, Los Angles, California. Using Acclaim’s quad-color technology, the Dyna Flood QA contains four colors, RGB+amber, under a single lens. Because quad-color technology mixes the colors under the lens unlike traditional technology that color mixes outside of the lens, Dyna Flood QA delivers precise color matching.

Dyna Flood QA offers beam angles of 20, 40 and 60 degrees, and provides 1,233 lumens with efficacy of 20.55. Consuming 60 watts, the long-lasting units are warranted for five years and retain 70 percent of brightness at 50,000 hours.

Ideal for facade and large-scale area flood lighting, the Dyna Drum HO features an adjustable yoke with onboard 180-degree flip inverted digital control display for menu selections and addressing. With its 100-277-volt AC internal power supply, Dyna Drum fixtures consume only 270 watts in replacing traditional 400-watt outdoor discharge fixtures.

The color-changing Dyna Drum HO features RGBW chips, while the single-color version is available in 2,700, 3,000, 3,500, 4,000 and 5,500 K, providing a lumen range of 9,000 to 17,232 at 5,500 K. The Dyna Drum HO is available in beam angles of 6 degrees standard, with 25-, 40- and 60-degree0-spread lens options.

Both Dyna Flood QA and Dyna Drum HO have an IP 66 wet-location rating. Their die-cast aluminum housings are available in gray, black and white to blend easily into the environment. The units mount to a standard 4-inch-round electrical box, and for simple connectability are designed with separate IP-rated power and signal cables, and bare end wires. With a DMX-512 control system, each unit features an auto-switching, multi-voltage power supply and an on-board touch-sensitive menu. The long-lasting units are warranted for five years.

The fixtures were installed by Carl Jones and Ken Ray, while the electrical wiring was completed by Jacobs Electric & Communications, LLC, Little Rock. James said, “This project went together much easier than anyone expected and out preformed expectations. It is an asset to Little Rock’s downtown, night time skyline.”
