The Authority on Dirty Power & Flashing Lights.
Professional C-Bus diagnostics for Sydney's grid-related lighting issues.
The Science of the Flicker
In New South Wales, the electrical grid isn't just delivering 50Hz power; it is carrying a hidden "Ripple Control" signal. These Zellweger Tones (often 750Hz or 1050Hz) are injected by utility providers to trigger off-peak equipment.
When these tones meet a dimmed LED circuit on a C-Bus network, they create Interharmonic Distortion. Because a dimmer has already "thinned" the power wave, these pulses cause the LED driver to fluctuate rapidly. This is why your lights only seem to "shiver" at night or when dimmed—your system is literally reacting to the grid's control signals.
The $110 Fix
Our Flicker-Free LED Downlights utilize active filtering drivers. They are engineered specifically for the Sydney grid to ignore ripple frequencies while maintaining smooth dimming curves on C-Bus Universal Dimmers.

Whole-Home Scrubbing
For large-scale properties, we install Zellweger Ripple Filters at the main switchboard. This hardware "scrubs" the incoming power of all high-frequency interference before it enters your automation dimmers.
