The DECC ( Duluth Entertainment and Convention Center) is Duluth's largest venue with several rooms and ballrooms for your wedding reception. Links to the large Harbor Side Ballroom and the smaller Horizon Room are in buttons above. This gallery page is for all of the other corporate events we light up at the DECC. Large events take place in Harborside Ballroom, Lake Superior Ballroom, and for the largest of them all: Pioneer Hall. Many of these photos in this gallery contain decor from a company out of Minneapolis that we work with all the time called Event Lab. Our lighting works wonders, but is even better when we have beautiful decor to light up like backdrops and set peices. For very large events like this we also work with two great local companies called Northland Special Events and The Hub for Event Logistics.
