LED technology has matured significantly. If you are still running halogen downlights, fluorescent tubes, or old CFL fittings, here is an honest look at whether upgrading makes sense for your property in 2026.
The primary driver behind LED upgrades has always been energy consumption, and the numbers are straightforward. A typical 50-watt halogen downlight can be replaced with an LED equivalent that uses around 8 to 12 watts — a reduction of approximately 75 to 85 percent. For a home with 20 halogen downlights, that reduction adds up quickly on the electricity bill.
Fluorescent tubes — common in commercial premises, garages, and kitchens — are less wasteful than halogens but still consume significantly more power than their LED replacements. A standard 36-watt fluorescent tube can be replaced with an 18-watt LED panel or tube, cutting consumption by roughly 50 percent while delivering equal or better light output.
CFL (compact fluorescent) globes were once considered the efficient option, but they are now outperformed by LED in every measurable way — energy use, lifespan, light quality, and startup time.
This is where LEDs pull away from every other lighting technology:
In practical terms, an LED fitting installed in a typical residential application will last 15 to 20 years before needing replacement. That means fewer globe changes, fewer callouts, and fewer maintenance costs — particularly in commercial settings where replacing fittings in high ceilings or hard-to-reach locations requires a licensed electrician and access equipment.
Halogen downlights are inefficient partly because they convert a significant portion of their energy into heat rather than light. A 50-watt halogen can reach surface temperatures above 200 degrees Celsius. In a Sunshine Coast home during summer, a ceiling full of halogen downlights is effectively adding a heating element to every room — forcing your air conditioning to work harder to maintain temperature.
LED downlights run significantly cooler. Reducing the heat load from your lighting can have a noticeable impact on air conditioning costs, especially in homes with multiple downlights across living areas and bedrooms. It is a compounding benefit: you save on lighting energy and you save on cooling energy.
The most common LED upgrade projects we handle include:
Sometimes, but not always. The answer depends on what you are upgrading from and the condition of your existing wiring and fittings.
For halogen downlight replacements, the existing halogen fitting is usually removed entirely and replaced with an integrated LED downlight. The wiring is retained, but the transformer (if present) is typically removed or bypassed. This is electrical work that requires a licensed electrician — it is not a matter of simply screwing in a new globe.
For fluorescent tube conversions, the approach depends on the fitting type. Some fittings can be retrofitted with LED tubes that use the existing housing. Others are more efficiently replaced with new LED panel lights or battens. We will assess your existing fittings and recommend the most cost-effective approach.
In older properties, the wiring and switchboard may also need attention to support the new lighting circuit configuration. We will identify this during the quoting process.
An LED upgrade makes clear financial sense when you are replacing halogen downlights, running lights for extended hours (commercial, strata common areas), or dealing with frequent globe failures. The payback period is typically 12 to 24 months through energy savings alone, after which the savings are pure reduction in your electricity costs.
Where it makes less sense is if you have recently installed quality CFL or fluorescent fittings that are performing well and have years of life remaining. In that case, a planned transition — replacing fittings as they reach end of life — may be more practical than a wholesale changeover. We will give you an honest assessment based on your specific situation.

In some cases, drop-in LED replacement globes are available for certain halogen fittings. However, the results are often inconsistent — compatibility issues with existing transformers, flickering, and reduced light output are common. For halogen downlights, replacing the entire fitting with an integrated LED downlight is the recommended approach. It provides better light output, longer life, and eliminates transformer compatibility problems.
That depends on the number of fittings, the type being replaced, and the condition of the existing wiring. Rather than quoting a generic range, we prefer to assess your specific property and provide an accurate, itemised quote. Call us for a free assessment — we will tell you exactly what is involved and what it will cost.
Not all dimmer switches are compatible with LED lighting. Older leading-edge dimmers designed for halogen globes can cause flickering, buzzing, or limited dimming range with LEDs. If you want dimmable LED lighting, the dimmer switch may need to be replaced with an LED-compatible trailing-edge dimmer. We handle this as part of the upgrade if needed.
