I just jumped onto ACL to send a message to a guru and I noticed a fairly large number. Not sure how normal this number is especially at this time of year but it definitely made me say hmmmm.
Things that make you say hmmm
- Thread starter AAH
- Start date
I must have scared 50 away 
This is most likely going to be AI bots scraping the public areas of the site.
Expect to see more of it as it scans through the content to train the models.
From a logged out ChatGPT, i asked the the following question:
==========
AusChristmasLighting (often abbreviated ACL) is one of the largest online communities focused on computer-controlled Christmas light displays, especially in Australia and New Zealand. It brings together hobbyists who design synchronized light shows using programmable LEDs, controllers, and sequencing software. Below is a detailed overview of the community, its notable figures, the content it hosts, and recent activity.
Key facts:
Typical components discussed:
It typically covers:
Example topics:
Members often:
Even outside the forum, hobbyists often recommend AusChristmasLighting as the best place to ask Australia-specific lighting questions. (Reddit)
In short:
AusChristmasLighting is a long-running DIY lighting community combining forums, tutorials, events, and shared resources to help hobbyists design increasingly sophisticated Christmas light displays.
If you want, I can also explain:

AusChristmasLighting (often abbreviated ACL) is one of the largest online communities focused on computer-controlled Christmas light displays, especially in Australia and New Zealand. It brings together hobbyists who design synchronized light shows using programmable LEDs, controllers, and sequencing software. Below is a detailed overview of the community, its notable figures, the content it hosts, and recent activity.
Overview of AusChristmasLighting
AusChristmasLighting is primarily a forum-based community dedicated to animated and computer-controlled Christmas lighting displays. The site serves as a hub for enthusiasts ranging from beginners to highly technical builders creating thousands-pixel light shows synchronized to music. (AusChristmasLighting)Key facts:
- ~21,000+ registered members
- ~16,000 threads and 140,000+ messages
- Open to hobbyists worldwide, though strongly Australia-centric. (AusChristmasLighting)
What the community focuses on
The core hobby is synchronized RGB light displays, where lights are controlled digitally to create animations timed to music.Typical components discussed:
- Addressable LED pixels (e.g., WS2811)
- Controllers using E1.31/DMX protocols
- Sequencing software such as xLights
- FM transmitters so viewers can tune in from their car
- Large props like mega-trees, matrices, singing faces, and pixel arches
Main content and resources
1. Forums
The forum is the community’s central resource. Major categories include:- Lighting controllers and hardware
- RGB pixels and intelligent lighting
- Sequencing software (xLights, xSchedule)
- Custom props and 3D-printed mounts
- Music and broadcast setups
- Display videos and show announcements
- Troubleshooting pixel failures
- Wiring layouts and power injection
- Sequencing techniques for animations
- Controller networking and firmware
2. The “ACL 101 Manual”
One of the community’s most important resources is the AusChristmasLighting 101 manual, a beginner guide explaining how to build a computer-controlled display from scratch. (AusChristmasLighting)It typically covers:
- Pixel types and voltages
- Power supplies and wiring
- Controllers and networking
- Sequencing basics
- Safety and weatherproofing
3. Shared sequences and show designs
Members frequently share:- xLights sequences (timed light animations)
- Model layouts
- Effects presets
- Audio timing tracks
4. Videos and tutorials
The community runs a YouTube channel featuring:- Tutorials
- recorded talks
- behind-the-scenes tours of displays
Example topics:
- pixel wiring and power injection
- building mega trees
- sequencing workflows
- troubleshooting controllers
5. Display showcase
Members post videos of their displays each year. Example recent uploads include sequences for songs like:- Uptown Funk
- Let It Go
- Carol of the Bells
Notable figures and contributors
The community is mostly hobbyist-driven rather than celebrity-driven, but several long-time contributors and moderators stand out.Administrators
- Ryan (ryanschristmaslights) – site administrator involved in organizing and moderating the forum. (AusChristmasLighting)
Moderators and active members
Examples of active contributors:- Skymaster – global moderator based in Western Sydney. (AusChristmasLighting)

- Other prolific members include:
- Johnnyboy
- Cranzy
- Juddge
- Zuseleets
Community culture
One notable aspect of the community is its collaborative culture.Members often:
- Share spare hardware
- Help each other fix shows close to Christmas
- Provide step-by-step build advice
Even outside the forum, hobbyists often recommend AusChristmasLighting as the best place to ask Australia-specific lighting questions. (Reddit)
Events and offline activity
The community organizes “Mini” expos, small regional meetups held in cities like:- Adelaide
- Sydney
- Brisbane
- Perth
- presentations on sequencing techniques
- demonstrations of new controllers
- workshops on building props
- networking between hobbyists
Recent developments (2024–2026)
Recent activity and trends in the community include:1. Continued forum growth
The site now reports:- 21k+ members
- 140k+ posts
showing continued expansion of the hobby. (AusChristmasLighting)
2. More advanced hardware discussions
