🎄 The Technology
Light-O-Rama Controllers
The display uses 12 computerized Light-O-Rama controllers, each capable of handling up to 30 amps and 16 independent channels. That’s up to 192 separately controllable light circuits across the entire display.
Each channel can turn lights on, off, brighten, dim, twinkle, and shimmer — giving the display its characteristic animated look that reacts to every note of the music.
| Controllers | 12 Light-O-Rama units |
| Channels per controller | Up to 16 |
| Max amperage per controller | 30 amps |
| Total channels | Up to 192 |
| Effects | On, off, brighten, dim, twinkle, shimmer |
| Connection | CAT 5 cable to Windows PC |
Light-O-Rama Sequencing Software
Every song in the show is programmed using Light-O-Rama sequencing software running on a Windows computer. Each song is mapped out channel by channel, beat by beat — telling each of the 192 channels exactly what to do at every moment.
Some songs use pre-built sequences from the Light-O-Rama community; others are uniquely created from scratch specifically for our display. A single song can take many hours to sequence properly.
| Software | Light-O-Rama (LOR) |
| Platform | Windows PC |
| Songs in show | 35 fully sequenced tracks |
| Sequence types | Community sequences + custom originals |
FM Transmitter — 106.9 FM
To let visitors hear the music synchronized with the lights from their car, we broadcast on 106.9 FM using a whole-house FM transmitter. The transmitter complies with FCC Part 15C, which governs the legal use of low-power FM transmitters.
The broadcast reaches approximately 100 feet from the house — plenty of range for visitors parked along Shenandoah Road. Just tune your car radio to 106.9 FM and enjoy the show!
