Frequently Asked Questions
Do I need a licensed electrician to replace downlights in NSW?
Yes. Replacing downlights is classified as electrical work in NSW and must be carried out by a licensed electrician. This applies even when swapping like-for-like fittings on an existing circuit. The only exception is replacing a plug-in globe in a fitting that uses a standard lamp socket — but most recessed downlights are hardwired and require a licensed electrician.
How long does a downlight installation take?
A standard LED replacement job takes approximately 15–20 minutes per light depending on ceiling access. A full home with 20 lights typically takes half a day. New wiring installations take longer depending on the number of points and ceiling access. We’ll give you a clear time estimate when we quote.
What’s the difference between fire-rated and non-fire-rated downlights?
Fire-rated downlights are required in certain locations — particularly where there is a floor above (such as in a two-storey home or apartment), or where specific building regulations apply. They are designed to maintain the fire integrity of the ceiling for a set period in the event of a fire. We assess this during installation and use the correct fitting for each location.
Can downlights be dimmed?
Yes — but not all LED downlights are dimmable, and dimmable LEDs require a compatible dimmer switch. If dimming is important to you, let us know when you book and we’ll ensure the fittings and switches we use are fully compatible. Retrofitting dimming to an existing installation is also straightforward.
What colour temperature should I choose for my downlights?
The most common choices are warm white (2700–3000K), which suits living areas, bedrooms, and anywhere you want a relaxed atmosphere, and cool white (4000K), which suits kitchens, bathrooms, and workspaces where clarity matters. Daylight (5000–6500K) is used in garages and workshops. If you’re unsure, warm white is the most popular choice for Hills District homes and works well throughout.
How many downlights do I need per room?
A commonly used guide is one downlight per square metre of ceiling, though this varies depending on the lumen output of the fitting and the ceiling height. A 15m² bedroom might need 8–10 lights, while a kitchen of the same size might need more due to task lighting requirements. We assess each room individually and recommend a layout that provides even, practical illumination.
Can you replace just some of the downlights, or does it have to be all of them?
We can replace as many or as few as you’d like. That said, mixing old halogen fittings with new LEDs in the same room will result in noticeably different light quality and colour temperature. Most homeowners choose to replace all lights in a room at the same time for a consistent result — and the per-light cost is lower when replacing more at once.
