An LED upgrade should start with what you want the lighting to do. Replacing inefficient lamps, improving task lighting and adding compatible dimming are different reasons to change a system—and may call for different work.
This guide covers the choices that affect the scope and cost, rather than promising a particular payback period.
Keep the fitting or replace it?
A compatible LED globe may suit an existing user-serviceable fitting. In other cases the fitting, driver, transformer or control also needs attention. Check the complete combination rather than choosing a replacement by its shape alone.
Hardwired fitting, driver and dimmer work needs an electrician. Do not open a fitting or enter a roof space to identify parts yourself.
Choose the light before choosing the quantity
Consider:
- Brightness: compare the light output in lumens, not just the electrical wattage.
- Where the light falls: beam angle, fitting position and shadows matter at benches, desks and mirrors.
- Colour appearance: warm, neutral or cooler light changes how a room feels.
- Colour rendering: product performance affects how objects and finishes look.
- Glare: a bright fitting in the wrong position can be uncomfortable.
- Controls: dimming, separate zones and suitable switches can make existing rooms easier to use.
There is no single fitting count that suits every room. A layout should account for furniture, cabinetry, ceiling height and the activities in the space.
What affects the installation cost?
- Whether existing positions and wiring can be retained.
- Whether lamps only, complete fittings or associated equipment are being replaced.
- Compatibility with existing transformers, drivers and dimmers.
- New cable routes, switching or separate lighting zones.
- Ceiling height and access, including any patching or repainting.
- Product specification and who supplies the equipment.
Combining work with a renovation can avoid reopening finished surfaces, but it does not guarantee a lower total price. Compare the actual scopes.
What about energy savings?
LEDs generally use less energy than halogen lamps for comparable light output. Actual savings depend on the products, how many are changed, hours of use and your electricity tariff. The Australian Government lighting guide (opens in new tab) explains energy-efficient selection.
For a meaningful comparison, use the actual wattages and usage—not a standard saving per room. Installation cost, product life and any maintenance also matter. A seldom-used room may have a different case for upgrading from lighting used every day.
Compatibility and maintenance
| Question | What to check |
|---|---|
| Will it dim? | The lamp or fitting must be dimmable and compatible with the control |
| Can existing supply equipment stay? | Transformer or driver suitability for the selected product |
| What happens if it fails? | Whether the lamp, driver or whole fitting is replaceable |
| Is it suitable for the location? | Moisture exposure, installation clearances and the product's rating |
| How long should it last? | Manufacturer-rated life and warranty, subject to installation and use |
LED equipment still needs appropriate installation clearances. A long rated life is not a promise that a driver or fitting will never fail.
What changes the scope
Some changes look small on paper but alter the amount of electrical work involved. Moving a fitting from its existing position means a new cable route and, often, patching. Adding a separate zone or a second switch position means new switching wiring rather than a swap at the ceiling. Introducing dimming to a circuit that was never dimmed can mean changing the switch, the driver and sometimes the fittings together.
Outdoor and bathroom locations bring moisture and clearance requirements that limit the products that can be used. High or raked ceilings change the access equipment needed. Older transformers left in the roof space from halogen downlights may need to be removed or replaced rather than reused. None of these are reasons to avoid the work, but each moves the job away from a simple lamp change, so mention them when describing the rooms.
Questions to ask when comparing quotes
- Are the fittings, lamps and drivers supplied by the electrician or by me, and are the models named?
- Are the existing positions and wiring retained, or does the price include new cabling and making good?
- Are the dimmers and switches included, and have they been checked for compatibility with the fittings quoted?
- What happens to the old fittings and transformers?
- What testing and compliance documentation is included for the circuits changed?
Compare like with like. A quote that replaces lamps in existing fittings and a quote that replaces the fittings, drivers and controls are different jobs, and the difference in price usually reflects that rather than one being poor value.
Planning the work
AB Electrical handles lighting installations and upgrades, including the circuit, fitting and control requirements. Tell us which rooms you want to improve, what is not working for you and whether you want to keep existing positions.
If lights are flickering, first establish whether there is a fault rather than assuming an upgrade is the answer. Our flickering-light guide explains the useful warning signs.
For a fitting that smells of burning, sparks or gives off heat, switch it off if that is safe and call 0405 343 343 from a safe place. For a planned upgrade, send an enquiry with your suburb, a short description of the rooms and what you want to change, and photos of the fittings only if they can be taken safely from the floor. Planned work is quoted in writing once the scope is understood.
