Heat Lights

After a single radiant heater for the ensuite, a dual fitting for the family bathroom, or a replacement globe for one that's blown? You're on the right page. This category covers standalone heat lamps and the globes that go in them. Nothing else.

If you actually want a fan, light and heater bundled into one ceiling fitting, the 3-in-1 bathroom heaters page is the better fit. Two different products, two different problems. Worth knowing which one you need before you order.

Heat lamps run on infrared globes. They warm you directly, not the air around you, which is why they feel good the second you flick the switch.

Types of bathroom heat lights

Three real buying choices on this page. Pick the one that matches what you're doing.

Single lamps suit tight spaces where one globe over the shower or towel zone does the job. Dual lamps spread warmth across a bigger room. Replacement globes are usually E27 screw base in R80 or R95 shapes, and most are 275W infrared.

Worth knowing. This is radiant heat, not fan-forced. It warms you, not the room. If whole-room warmth matters more, have a look at radiant heating as a broader category.

Installation and Australian compliance

Heat lamps in bathrooms have to follow AS/NZS 3000, the wiring rules that split the bathroom into zones based on how close fittings sit to water.

Zone 1 is directly above the bath or shower. Fittings here need a high IP rating and careful placement.
Zone 2 is the area immediately around Zone 1. IP44 minimum, meaning splash-resistant from any direction.
Outside zones covers the rest of the ceiling. Most standard heat lamp fittings sit here.

Keep the fitting clear of insulation and timber per the manufacturer's clearance spec, usually printed on the box. And this isn't a DIY job. A licensed electrician has to install or hardwire any bathroom heat lamp in Australia.

Replacing a heat globe

Check the base of the old globe first. The code (E27, R80, R95) and wattage are printed on the metal cap or the glass. Match that exactly when you order the new one.

Switch the power off at the switchboard before you change it, not just at the wall switch. Let the globe cool fully or you'll burn your fingers.

If all globes blow at once, or the circuit trips when you switch on, it's the fitting itself, not the globes. Time to replace the unit.

Looking after the fitting

Wipe the fascia with a dry cloth when the unit is cool. Don't spray cleaner directly onto the fitting or the globes. On dual lamp units, replace both globes at the same time even if only one has blown. The other won't be far behind, and matched globes give even heat across the fascia.

After a combo unit? The 3-in-1 bathroom heaters page has fan, light and heater in one fitting. For whole-room warmth, radiant heating covers panel and strip heaters. Non-heat ceiling fittings sit under bathroom lighting. And heated towel rails work nicely alongside a heat lamp as a second, gentler heat source.
