Our 2020 display has 35,295 lights in six colors (Red, Yellow, Green, Blue, Violet, and White).
The lights we are using this year require 120A (14,400W) of electricity when they are turned on all at once. Fortunately we don't turn them on all at once most of the time (although a couple songs do for a brief moment). This year's display required about 1,800 ft. of custom extension cords.
Light Counts (how we've grown):
2010: No Show
With all the lights and power in place comes the real challenge: synchronizing them to music. Doing so requires a way to interface the lights with a computer, and a way to program the computer with a set of commands to tell the lights what to do (and when to do it). The electronics necessary to make this happen consist of D-Light controllers running the open source DMX firmware. The software which controls the lights is known as Aurora (we wrote it). Each song takes about 10 hours of time to synchronize to music. The music is transmitted to visitor's FM radios by a low power FM transmitter on an empty FM station.
Channel Counts (how we've grown):
2005: Not animated
2006: 63 (8x D-Light ACx8)
2007: 96 (8x D-Light ACx8, 1x D-Light DCx16, 2x D-Light ACx16)
2008: 210 (8x D-Light ACx8, 1x D-Light DCx16, 6x D-Light ACx16, 4x D-Light Firefli)
2009: 368 (6x D-Light ACx8, 1x D-Light DCx16, 6x D-Light ACx16, 4x D-Light Firefli, 1x DMX Intelligent Light)
2010: No Show
2011: 368 (6x D-Light ACx8 DMX, 1x D-Light DCx16 DMX, 6x D-Light ACx16 DMX, 4x D-Light Firefli DMX, 1x DMX Intelligent Light)
2012-2018: 368 (6x D-Light ACx8 DMX, 3x Blizzard Q12W DMX, 6x D-Light ACx16 DMX, 4x D-Light Firefli DMX, 1x DMX Intelligent Light)
2019-2020: 388: Added an additional Blizzard Q12W and a Lynx controller.
Setting It All Up:
So, with all of that in place, how long does it take to hang all of those lights? The time required has greatly improved over the years. Early on, when everything was new to build, it took every day for a full month to set up. The setup of our 2019 display began in the first week of November and took until November 27 to complete. Most of that is on weekends instead of every day. They all come down in just a day or two though.
Of particular interest is our 16 foot tall animated Christmas tree. First used in 2006, this display element was custom made by us out of plumbing parts just for this display. The support pole and star were assembled on the ground and then raised into place and anchored by four steel cables. A shape ring was then constructed at the base of the tree. Lights were raised onto the tree and secured between the eye bolts at the top and the shape ring at the bottom. The mega tree consists of 13,240 lights. The Mega-Tree topper was damaged during a wind storm during the 2015 season and a new topper was built for 2016. The topper was upgraded from plywood to a custom 3D printed star in 2019.
Our Mega Tree is circled by 48 "mini trees". These are made by wrapping three strings of incandescent mini lights around a floral easel. The mini trees havea combined count of 14,400 lights.
The Leaping Arches
Introduced in 2008 are the four arches in the foreground of the display. These arches each consist of 16 individually controllable RGB pixels contained on a D-Light Firefli strand. This allows us to control the exact color out of 16 million possible colors that each pixel should be throughout the show.
The Animitronic Santa
Added in 2019 is a animitronic Santa who dances to the music in a few places in the show. He also moves his mouth to "speak" one of our radio announcements. Santa was originally a novelty dancing/talking Santa that we found at the hardware store. We modified him to be able to control him from our show sequences.
So how much is the electric bill?
Because the lights are not always on (each "channel" is only on for brief periods of time) the bill is far less than you might guess. In 2018 it only cost $80 to run the display for the entire Christmas season. Our anticipated electricity cost this year is calculated to be very slightly more. Electricity turns out to be one of the cheapest things in the entire display. Replacing worn bulbs each year is far more expensive than the electricity.
What changes were made for 2019/2020?
Several light strings (including all of the incandescent green on the Mega Tree) required replacement. In 2019 we added an animitronic talking/dancing Santa. Some show sequences were updated/modified, and the show playlist was changed. One new sequence was added.
