Downlights are a fair dinkum staple in Aussie homes, giving our kitchens, living rooms, and hallways that clean, modern look. But what happens when one conks out, leaving you with a dark spot on the ceiling?

Figuring out how to change a downlight can seem simple, but it depends entirely on the type of downlight you have. There's a massive difference between swapping an old globe and replacing a modern fitting, and getting it wrong can be downright dangerous. This guide tells you what you can do, and when you absolutely must call a pro.

Scenario 1: Just Changing the Globe (The Old-School Halogen or LED Globe)

If you have older-style downlights (often installed before around 2012), you might just need to replace the globe (bulb) inside the fitting. This usually involves a halogen globe or an early type of replaceable LED globe. This can be a safe DIY job, but only if you follow these steps precisely.

Step 1: Safety First! Kill the Power!

This is non-negotiable, mate. Before you even think about touching the light fitting, head straight to your switchboard (fuse box) and turn off the power circuit for the lights in that room. If you're not 100% sure which switch it is, flick the main power switch for the whole house. Better safe than sorry.

Step 2: Let it Cool Down

If the light was just on, especially if it was an old halogen globe, it will be stinking hot enough to fry an egg. Give it a good 10-15 minutes to cool down completely before you touch anything.

Step 3: Release the Fitting (Carefully!)

Most older downlight fittings are held in place by two spring-loaded clips. Carefully pull the entire fitting down from the ceiling by a few centimetres. You should feel the clips resisting. Reach your fingers in behind the fitting (watch out for sharp edges!) and carefully squeeze the two arms of one spring clip together, then gently guide it out of the ceiling hole. Repeat for the other clip. Let the fitting hang down carefully by its wire – don't let it snap back!

Step 4: Swap the Globe

• For GU10 Globes: These have two short, chunky pins. You need to push the globe gently upwards into the socket, twist it anti-clockwise about a quarter turn, and it should pop out. To put the new one in, line up the pins, push gently, and twist clockwise until it locks.
• For MR16 Globes: These have two thin, straight pins. They usually just pull straight out of the socket. Line up the pins of the new globe and push it gently but firmly back in. Crucial Tip: If you're replacing a halogen globe, try not to touch the new glass bulb with your bare fingers. The oils from your skin can create hot spots and shorten its life. Use a tissue or clean cloth.

Step 5: Put it Back Together

Carefully squeeze the spring clips together again and guide the fitting back up into the ceiling hole until it sits flush. Turn the power back on at the switchboard and test your new globe. Sorted!

Scenario 2: Replacing the Entire Fitting (The Modern Integrated LED Downlight)

Now, this is a completely different kettle of fish. The vast majority of new LED downlights installed in Australia today are fully sealed, integrated units. You cannot just change the 'globe' because the light source and the fitting are all one piece. If one of these fails, the entire fitting needs to be replaced.

This is 100% NOT a DIY Job

Let's be absolutely crystal clear. Replacing an entire downlight fitting involves disconnecting and reconnecting 240V electrical wiring up in your ceiling cavity. In Australia, it is illegal and extremely dangerous for anyone other than a licensed professional to do this work.

This work must only ever be carried out by a licensed electrician. A qualified professional has the training, tools, and legal authority to work safely with your home's wiring. They will ensure the new fitting is installed correctly, is compatible with any existing dimmers, meets all insulation clearance requirements (using IC-rated fittings where needed), and complies with all Australian standards. Don't risk your life or your home insurance trying to save a few bucks.
