Deanna Rose Farmstead To Entertain with Innovative Holiday Lighting Display


Successful Local Entrepreneur and Lighting Controls Specialist Utilizes New Technology to Transform City of Overland Park Venue into Intriguing Destination for Viewing Holiday Lights

OVERLAND PARK, KS — An Overland Park entrepreneur is transforming his childhood fascination with holiday lights into a new world of wonder for area families who visit the City of Overland Park’s Deanna Rose Children’s Farmstead this holiday season.

Mark Callegari, an Overland Park resident who has built many software and technology companies, has underwritten the costs to build and produce a holiday light park at the popular children’s attraction. Working with Deanna Rose officials, Callegari and his team have choreographed a lighting show synchronized to many popular holiday songs. The entire attraction is operated by newly designed lighting controls software and hardware with leading-edge features and effects.

The holiday lighting show opens Thanksgiving evening (Nov 28, 2013) and runs through Jan. 5, 2014. Hours are 5 p.m. to 10 p.m. each night with 20-minute lighting shows that start on the hour. The display is visible from the parking lot of the facility, where visitors can view the lights from the comfort of their cars like an old-fashioned drive-in movie. The music will be broadcast on an FM radio station. The event is free.

The Deanna Rose Children’s Farmstead is located at 13800 Switzer Road, Overland Park, KS 66221.

Lighting Moved to Deanna Rose After Outgrowing Neighborhood Location

For many years, Callegari’s holiday lighting display has entertained thousands of visitors to his Overland Park home. The popularity of the display and traffic finally reached such a high level last year that Callegari sought a new location to help ease congestion in his neighborhood.

With the new site at Deanna Rose, Callegari has re-located many elements of his traditional display as well as added numerous new attractions.

  • A unique LED-illuminated flat panel tree-shaped display, dubbed “The Ultimate Holiday Tree”, is one of the feature attractions. The tree, featured on HGTV’s “All Out Christmas” show, is illuminated with thousands of solid-state LEDs and delivers bright lighting effects, video-like effects, colorful moving patterns, and super large text messages that are precisely synchronized to music that celebrates the holiday season.
  • In addition to the Ultimate Holiday Tree, visitors will enjoy unique LED-based displays including giant spheres, a whimsical tree forest, a 20-foot-tall color-changing star, and hundreds of additional color-controlled LEDs adorning the Farmstead’s trees and buildings.
  • Underlying the user experience is Pango, a new generation of LED control technology being demonstrated for the first time. This technology allows thousands of full-color (RGB) LEDs to be precisely controlled and synchronized to music on a note-by-note basis. The result is a lighting and music experience that many believe equals or surpasses the experience at a Disney-level resort. (Earlier versions of the patented lighting control software are used in lighting installations worldwide including the Marriott Hotel in downtown Kansas City, MO.)

“We’ve constructed a dazzling light show,” Callegari said. “We’ve integrated our advanced lighting controls to manage thousands of LED lights while using very little energy.”
