Event lighting
Custom-controlled lighting for events and installations.
Addressable LED Systems
WS2812/NeoPixel driver firmware, sound-reactive effects, event lighting and ESP32-based LED controllers.
Overview
What this service covers
Driver firmware and controller hardware for WS2812/NeoPixel-class addressable LEDs — the engineering behind custom RGB effects, sound-reactive lighting and event installations, not just off-the-shelf strip controllers.
Client Problems
Problems this service solves
- Off-the-shelf LED controllers don't support the effect or scale needed.
- Sound-reactive lighting needs to sync to audio in real time.
- An app is needed to control an installation instead of a physical remote.
- A large installation needs multiple controllers synchronised.

Development Process
How we approach an LED project
- 01Effect & scale requirements
Confirm the installation size and effects needed.
- 02Controller hardware selection
Choose ESP32 hardware and LED type to match the scale.
- 03Firmware & effect development
Build and test driver firmware and effects.
- 04Installation testing
Validate on-site before handoff.
Deliverables
What you receive
- Firmware source code
- Controller hardware design, where custom hardware is built
- Effect configuration documentation
Testing & Validation
How LED installations get validated
Effect timing and audio-reactive response are checked on the bench first, then again on-site once the LEDs are actually mounted, since run length, power injection points and ambient light change how an effect reads in the real installation compared to a test rig. For multi-controller setups, synchronisation is validated across the full run before handoff, not just on a short test segment.
Applications

How We Can Help
How PAK-EL LAB Can Help
If an off-the-shelf controller can't handle the scale or effect you need, we can build the driver firmware, controller hardware and control app together, or focus on whichever piece is missing. Scope, deliverables, schedule and quotation are confirmed once we know the installation size, the effects you have in mind, and whether audio-reactivity or multi-controller sync is part of it — those details change the design enough that a generic estimate isn't useful up front. We work with clients internationally and collaborate remotely as standard practice.

FAQ
Frequently Asked Questions
Which addressable LED types do you support?
WS2812, NeoPixel and SK6812-class addressable LEDs are the common starting point; the driver firmware is written for the specific LED protocol your installation uses.
Can lighting sync to live audio in real time?
Yes, sound-reactive effects are built around real-time audio input processing so the lighting responds as the sound happens, not on a noticeable delay.
Can multiple controllers be synchronised for a large installation?
Yes, multi-controller synchronisation is part of scaling an installation beyond what a single ESP32 can drive on its own.
Do you provide an app to control the lighting?
Where the project needs one, yes — a Wi-Fi/BLE control app is a common addition alongside the controller firmware.
