This light globe guide covers the three things you need to get right before you buy: the base (how it fits the fitting), the lumens (how bright it is), and the colour temperature (how warm or cool the light looks). Match those three to the room and you'll never bring home the wrong globe again. Here's how each one works.
Which base does your fitting use?
The base is the fitting that connects the globe, and getting it wrong is the number one reason a globe won't fit. Australian homes use a handful of common types, so identify yours before anything else.
- B22 (bayonet): The classic Aussie push-and-twist base found in many older fittings and lamps.
- E27 (Edison screw): A large screw base, extremely common in modern fittings and imported lamps.
- E14 (small Edison screw): A narrower screw base used in smaller fittings, rangehoods and appliances.
- GU10: A twist-lock pin base used for mains-voltage downlights.
- MR16 (GU5.3): A push-pin base for low-voltage downlights that run off a transformer.
If you're unsure, take the old globe with you or photograph the base and any tiny code printed on it. Appliance globes are a common trap, for example a Philips E14 oven globe must be heat-rated for its enclosure, so never substitute a standard household globe there.
Why lumens matter more than watts
For decades we judged brightness by watts, but with LED that habit will steer you wrong. Watts measure energy used, not light produced. Lumens measure actual brightness, and that's the number to read on the box.
An LED globe produces the same light as an old incandescent for a fraction of the watts, which is exactly why your power bill drops. As a rough guide for household globes:
| Old incandescent | Approx. lumens | Typical LED watts | Good for |
|---|---|---|---|
| 40W | ~450 lm | 4-6W | Lamps, bedside, ambient |
| 60W | ~800 lm | 7-9W | Living rooms, bedrooms |
| 75W | ~1100 lm | 10-12W | Kitchens, larger rooms |
| 100W | ~1600 lm | 13-15W | Bright task areas, garages |
These figures are indicative, so always check the lumen rating printed on the specific globe you're buying rather than assuming.
Warm or cool: choosing colour temperature
Colour temperature is measured in kelvin (K) and decides whether a room feels cosy or crisp. It's the difference between light that helps you wind down and light that helps you focus, so it's worth matching to the room.
- Warm white (2700K-3000K): A soft, yellowish glow that suits bedrooms, living rooms and dining areas.
- Cool white (4000K-4500K): A neutral, balanced light that works well in kitchens, bathrooms and laundries.
- Daylight (5000K-6500K): A bright, bluish-white light best for garages, workshops and detailed task work.
A common mistake is putting daylight globes in a lounge, which can feel clinical and harsh. If you like flexibility, some globes and fittings offer selectable colour temperature so you can change the mood without swapping globes.
Should you buy dimmable globes?
Dimming lets you drop the brightness for evenings, movies or a relaxed dinner, but there's a catch worth knowing. Not every LED globe is dimmable, and fitting a non-dimmable globe to a dimmer switch causes flicker, buzzing or a shortened life.
Always check the box says "dimmable" if you're using a dimmer. It also helps to pair dimmable LEDs with a modern LED-compatible dimmer, since older dimmers were built for incandescent loads and can misbehave.
Fittings with dimming built in sidestep the guesswork entirely. A piece like the Buckley dimmable LED floor lamp gives you adjustable brightness without matching a separate globe and dimmer, and you'll find plenty more options across our home lighting range.
Battery-powered lighting for tricky spots
Not every spot has a nearby power point, and that's where battery lighting shines. Rechargeable wall lights let you add a glow to a reading nook, hallway or rental wall without an electrician. Something like the rechargeable wall sconces with remote mount anywhere and dim to suit the moment.
Match the globe to the room
Once you understand the three basics, choosing per room becomes quick. Here's a simple way to think about it.
- Bedrooms: Warm white, moderate lumens, dimmable if you like reading in bed.
- Kitchens: Cool white for clarity on benches, with bright task lighting over prep areas.
- Bathrooms: Cool white and moisture-appropriate fittings for accurate grooming light.
- Living areas: Warm white and dimmable for a flexible, relaxed feel.
- Garages and sheds: Daylight and high lumens so you can see detail clearly.
Common light globe mistakes to avoid
A few simple errors send more globes back to the shop than any fault ever does. Keep this short checklist from our light globe guide in mind and you will sidestep almost all of them.
- Guessing the base from memory. A B22 bayonet and an E27 screw look similar in a dim room but will not swap, so always check the code or take the old globe with you.
- Buying on watts alone. With LED the wattage is tiny, so a low number does not mean a dim globe. Read the lumens to know how bright it really is.
- Putting a standard globe in an enclosed or appliance fitting. Sealed oyster lights, ovens and rangehoods trap heat that cooks an ordinary globe, so only fit ones rated for the enclosure.
- Mixing colour temperatures in one room. A warm globe beside a daylight one looks mismatched and unsettling, so keep every globe in a space to the same kelvin rating.
- Fitting a non-dimmable globe to a dimmer. The result is flicker, buzz and early failure, so match dimmable globes to a dimmer switch every time.
How many globes and what brightness for Australian rooms
Working out how much light a room needs is easier than it sounds. Add up the lumens from every globe in the space and compare it to the size of the room. As a rough starting point, a cosy bedroom of around three by three metres is comfortable with roughly 2,000 to 3,000 lumens in total, while a family kitchen of a similar size wants closer to 4,000 to 5,000 lumens because you are working with knives and hot pans and need to see clearly.
A living room sits between the two, and dimmable globes let you dial a bright, well-lit space back to a relaxed glow for movie nights. Garages and workshops benefit from more again, spread across several fittings so you are not casting hard shadows over the bench. Spreading the total across two or three globes almost always looks better than forcing it through a single bright fitting, which tends to glare and leave the corners gloomy. If a room still feels dim after you have added up the numbers, the fix is usually more fittings rather than one blindingly bright globe.
Care and safety tips
LED globes are low-maintenance, but a few habits get the most from them. These small steps also keep replacements safe and tidy.
Let a globe cool before handling it, and switch off at the wall before changing one. Keep enclosed and appliance fittings to heat-rated globes only, since heat build-up shortens the life of the wrong globe fast.
When a globe does fail, dispose of it responsibly rather than in general waste, especially older fluorescent tubes. Keeping spares on hand for common bases saves a dark-room scramble, and you can stock other everyday essentials from our household essentials range at the same time.
Frequently asked questions
How do I know which light globe base I need?
The easiest way is to remove the old globe and check the base, or photograph it with any code printed on it. Bayonet bases (B22) push and twist, while Edison screw bases (E27 large, E14 small) screw in. Downlights typically use GU10 or MR16 pins. Taking the old globe shopping removes all doubt about the fit.
What is the difference between lumens and watts?
Watts measure how much energy a globe uses, while lumens measure how much light it actually produces. With LED globes you get high lumens for very low watts, which is why they cut power bills. When comparing brightness, read the lumen figure on the box, not the watts, as watts no longer reliably indicate how bright a globe will be.
Which colour temperature is best for a living room?
Warm white, around 2700K to 3000K, suits living rooms best. It gives a soft, relaxing glow that feels cosy in the evening and flatters furnishings and skin tones. Cooler daylight globes can feel clinical in a lounge. If you want flexibility, choose dimmable warm-white globes so you can brighten the room for tasks and lower it for relaxing.
Can I use any LED globe with a dimmer switch?
No. Only globes clearly labelled dimmable will work properly on a dimmer. Fitting a non-dimmable LED to a dimmer can cause flickering, buzzing or a shortened lifespan. For best results, pair dimmable LED globes with a modern LED-compatible dimmer, since older dimmers were designed for incandescent bulbs and may not dim LEDs smoothly across the full range.
