FAQ's

Flickering usually occurs when modern LEDs are paired with an older, incompatible dimmer switch designed for high-wattage incandescent bulbs. Because LEDs draw very little power, they can fall below the dimmer’s minimum electrical load, confusing the internal LED driver and causing erratic strobing, flashing, or limited dimming ranges.

Leading-edge dimmers are traditional switches designed for high-wattage halogen and incandescent bulbs. Trailing-edge dimmers utilise advanced transistors to control the electrical current smoothly. Trailing-edge models are specifically engineered for low-wattage electronics, making them the superior choice for quiet, flicker-free LED dimming.

No. You must specifically purchase bulbs explicitly labelled as "dimmable." Attempting to dim a non-dimmable LED bulb will quickly damage the internal driver, leading to rapid flickering, buzzing, or immediate failure. Always check the product packaging or specifications sheet before installing.

An audible hum or buzz indicates an electrical mismatch between the LED driver and the wall dimmer switch. This occurs when the voltage waveform is cut abruptly. To fix this noise issue, have a licensed electrician upgrade your wall switch to a high-quality, fully compatible trailing-edge or universal LED dimmer.

Yes. In New Zealand, replacing or installing a wall switch involves working with 230V mains electricity, which poses serious risks of shock or fire if done incorrectly. We strongly recommend using an NZ Registered Electrician to ensure safety, protect your product warranty, and guarantee your dimmer is compatible with your LED lights.
