How We Build the Show: Behind the Scenes in October & November

Every year on November 27th at 5:30 PM, the lights come on and the music starts. To visitors, it looks effortless — a house full of perfectly synchronized color that seems to appear overnight. But the truth is that the show takes nearly two full months to build. Here is an honest, behind-the-scenes look at what happens from October 1st through opening night.

📅 The Full Setup Timeline

• Early October — Storage and InventoryControllers, extension cords, props, and light strings come out of storage. Every item is tested before it goes up. Burned-out strings and failed channels get replaced now, not on opening night.
• Mid-October — Controller MountingAll 12 Light-O-Rama controllers are mounted along the house. CAT 5 cable runs from each controller back to the Windows PC inside. Each controller handles 16 channels — 192 total across the display.
• Late October — Light String LayoutThousands of feet of light strings go up: roofline, bushes, trees, arches, candy canes, wireframes. Everything is mapped to a specific channel on a specific controller. Change one wire and the programming breaks.
• Early November — FM Transmitter SetupThe 106.9 FM transmitter is tested and positioned. It operates under FCC Part 15C with a range of roughly 100 feet — just enough to reach the cars parked on Shenandoah Road.
• Mid-November — Sequence Programming & TestingEvery song in the show has a sequence — a frame-by-frame map of which channels turn on and off, and when. Sequences are reviewed, timed, and loaded into the Light-O-Rama show scheduler.
• Week Before Thanksgiving — Full Run-ThroughsWe run the complete show at night to catch anything that does not look right. A channel that fires slightly off-beat, a light string that flickers instead of strobes, a prop that is too dim to see from the street. All of it gets fixed.
• November 27 — Opening Night5:30 PM. The show starts. Whatever is not perfect just has to be good enough until the next maintenance window.

🔌 The Light-O-Rama System

The backbone of the show is Light-O-Rama (LOR) — a system originally designed for professional holiday decorators that has become the standard for hobbyist synchronized shows across the country. Our setup includes:

• 12 LOR controllers at 30 amps each, providing 16 channels per controller
• 192 total channels of independently controllable circuits
• CAT 5 network cable daisy-chained between controllers and running to the house
• Windows PC running LOR software, which plays audio and sends lighting commands simultaneously

Each “sequence” in LOR is essentially a spreadsheet: rows are channels, columns are time (typically down to 1/10th of a second), and each cell tells that channel to be on, off, dimmed, or fading. A three-minute song might have 18,000 individual cells to fill in. Multiply that by 35 songs and you start to understand why setup takes two months.

🏠 Why It Gets Harder Every Year

When the show started in 1996, it was a simple static display — lights went up, lights came on, lights came off at bedtime. No synchronization, no FM transmitter, no computer. Over 30 years, we have added channels, controllers, props, and complexity every single season.

More channels means more things to mount, more cable to run, more channels to map, and more sequences to program. It also means more things that can fail. A controller that worked fine in January when we put it in storage can develop a bad channel by the time October rolls around. We test everything, but surprises still happen.

🤵️ What You Can Do to Help

We start breaking the show down on January 2nd. Everything goes into labeled bins and heads back to storage, and by January 15th there is almost no sign that any of this ever happened. Then, sometime in late September, we start thinking about what we want to add for next year — and the whole process begins again.

We hope this gives you a little more appreciation for what you are looking at when you pull up to 12 Shenandoah Road. See you this November 27th at 5:30 PM!
