Your halogen downlights still work, so why change them? Maybe one blew again last month, or the ceiling gets uncomfortably warm on a summer night, or your power bill keeps creeping up. If you have been weighing up whether to switch your old halogens for LED, here is a plain look at what actually changes, what it costs you to keep the halogens, and whether the upgrade is worth it for your home.
The short answer
For most Melbourne homes, yes, it is worth it. LED downlights use far less power for the same brightness, they last for years instead of months, and they run cool instead of pumping heat into your ceiling. Halogen downlights are cheap to buy but expensive to run, and they are slowly disappearing from shelves. If you are replacing blown globes every few months, you are already paying the LED premium in dribs and drabs, just without the benefits.
Halogen vs LED: what actually differs
Halogen downlights work by heating a filament until it glows. Most of the energy they draw turns into heat, not light. That is why a halogen globe gets hot enough to burn your hand and why a room full of them makes the space warmer.
LED downlights produce light through a small electronic chip. They draw a fraction of the power for the same light output and stay cool to the touch. A halogen downlight typically pulls around 50 watts. An LED giving off the same brightness usually sits somewhere between 6 and 10 watts. Across a house with twenty or thirty downlights, that difference adds up every single night.
Running cost and lifespan
This is where the real gap shows. Halogen globes are cheap on the shelf but they fail often, sometimes within a year, and they burn through power the whole time they are on. LED downlights cost more up front but they last for many years and sip electricity by comparison.
Over the life of the fitting, LEDs win comfortably on total cost. You stop buying replacement globes, you stop dragging the ladder out every few months, and your lighting draws a lot less off the meter. If you have ever grumbled about how often a downlight in the kitchen or hallway needs changing, that alone is a strong reason to switch.
Heat, safety and your ceiling
Halogen downlights run hot, and that heat has to go somewhere. In older homes especially, that means heat radiating up into the ceiling cavity, close to insulation and timber. Old-style halogen fittings needed clearance from insulation for exactly this reason, which left gaps in your ceiling insulation and let warm air escape in winter.
LED downlights run cool, and many modern fittings are rated to sit in direct contact with insulation. That means a tidier, better-insulated ceiling and one less heat source sitting above your head. For anyone thinking about the safety of ageing halogen fittings, this is a genuine upgrade, not just a power saving.
Light quality: will it look different?
Good LED downlights look as warm and bright as halogen, and often better. The thing that trips people up is colour temperature. Halogen gives a warm, slightly yellow light. LEDs come in different colour temperatures, from warm white through to a cooler daylight tone.
For living rooms and bedrooms, a warm white LED gives you that familiar cosy feel. For kitchens, bathrooms, and laundries, a neutral or cooler white shows detail better. Dimmable LEDs are widely available too, but they need a compatible dimmer, which an old halogen dimmer often is not. A good electrician will match the colour temperature to each room and sort the dimming so the result feels right, not clinical.
Can you just swap the globes yourself?
Sometimes, but not always, and this is where people get caught out. Some halogen fittings take a simple LED globe replacement. Many do not. A lot of older halogen downlights run through a transformer that LEDs do not play nicely with, which leads to flickering, buzzing, or globes that fail early.
The cleaner long-term fix is to replace the whole fitting with a purpose-built LED downlight, wired properly and matched to your ceiling. That is electrical work, and in Victoria it needs a licensed electrician for downlight installation. It also gives you a fitting that is rated for insulation contact and built to last, rather than an LED globe forced into a fitting never designed for it.
What the upgrade involves
A downlight upgrade is usually a straightforward job. The electrician removes the old halogen fittings and transformers, fits new LED downlights, and connects them safely. In many homes the existing holes in the ceiling are reused, so there is little to no patching. If you want to change the layout, add lights to a dark corner, or move to dimmable zones, that can be built into the same visit.
If you are lighting a whole home or planning a renovation, it is worth stepping back and looking at the full picture rather than swapping fittings one by one. Our LED lighting upgrades and broader lighting installation services cover everything from a simple downlight swap to a full lighting plan for a new build or extension.
So, is it worth upgrading?
If your halogens keep blowing, your ceiling runs hot, or your power bill bothers you, the answer is almost certainly yes. LED downlights cost more to buy but they pay you back through lower running costs, far fewer replacements, and a cooler, safer ceiling. For most homeowners the question is not whether to switch, but when.
