Choosing a globe holder is a small decision that affects fit, safety and the way a fitting can be used. The holder must match the globe base, the fitting's voltage and the environment around it. A B22 bayonet holder is not interchangeable with an E27 screw holder, and a GU10 connector is a different part again.
Globe holder types at a glance
| Holder or connector | Globe base | Typical use | First check |
|---|---|---|---|
| B22 bayonet | B22 | Ceiling lights, wall fittings and lamps | Push-and-twist fit and holder heat rating |
| E27 Edison screw | E27 | Pendants, table lamps and decorative fittings | Thread size, globe shape and available clearance |
| GU10 connector | GU10 | Downlights and directional spotlights | Twist-lock pins, cut-out and fitting depth |
| G9 or G4 bi-pin | G9 or G4 | Compact decorative and low-voltage fittings | Pin spacing, voltage and transformer requirements |
This comparison is a starting point rather than a compatibility guarantee. Read the fitting label and the globe information together before ordering. If you are replacing a complete fitting, browse the globe, bulb and lamp holder collection for the relevant base type.
Choose the holder by globe base
B22 bayonet holders
B22 holders use two side pins. The globe is pushed into the holder and turned until it locks. They are common in general ceiling and wall fittings. Check that the contacts are clean and that the holder grips the globe without excessive movement.
E27 screw holders
E27 holders accept a standard 27 mm Edison screw base. They suit many pendants, floor lamps and table lamps, including decorative filament globes. Leave enough room for the globe to clear the shade and never force a different thread into the holder. For lamp-based applications, compare the holder with the fitting and the options in our table lamp collection.
GU10, G9 and G4: compact holders and connectors
GU10 connectors for downlights
GU10 globes use two short pins that lock with a twist. The connector is usually part of a recessed or surface-mounted spotlight. Confirm the cut-out, fitting depth and whether the holder is intended for the globe and lamp body you plan to use. Our GU10 connector is a useful reference when you are replacing the connector rather than the entire fitting.
G9 and G4 bi-pin holders
G9 and G4 holders are used in compact fittings, but they are not interchangeable. G4 lamps commonly operate at low voltage, so check whether a transformer or suitable driver is required. G9 lamps are a separate base and voltage category. A globe that looks close in size can still be the wrong electrical match.
For bathroom applications, the bathroom lighting collection is a better starting point than adapting an indoor lamp holder without checking its moisture protection.
How to choose a holder for the installation
1. Check the electrical details
Match the holder to the globe's voltage and maximum wattage. LED globes usually produce less heat than older halogen lamps, but the fitting still needs to be suitable. Never connect a 12V G4 lamp directly to a 230V supply.
2. Check heat and clearance
Enclosed fittings can hold heat around the holder and globe. Confirm the manufacturer's limits, leave the intended clearance around the lamp and avoid fitting a higher-wattage globe simply because it fits the thread.
3. Check moisture and dust
Outdoor areas, bathrooms and covered patios need an appropriate IP-rated fitting. A standard indoor holder is not automatically suitable because it sits under a roof. For garden or exterior work, compare the fitting with outdoor lighting rather than relying on the holder alone.
What a replacement connector should match
A replacement connector should match the globe base and the fitting, not just the visual shape of the old part. Compare the pin arrangement, mounting method and lead connections. If the original connector is part of a complete downlight, replacing the fitting may be safer than adapting an unrelated holder.
Use a product image as a visual check, then confirm the written specification and installation requirements before ordering. The GU10 connector listing is relevant when the job involves a GU10 replacement rather than a B22 or E27 lamp holder.
Replacing a holder safely
Switch off the circuit at the distribution board, not only at the wall switch, and confirm that the circuit is dead before touching wiring. A holder replacement can involve live mains conductors, earthing and strain relief. If the fitting is fixed, outdoors, in a bathroom or requires rewiring, use a qualified electrician.
For a plug-in lamp, the safest route is often to replace the complete lamp-holder assembly with a correctly rated part. For a ceiling fitting, record the existing base type and wiring arrangement before buying anything. Do not use an adaptor to hide an uncertain voltage or mechanical fit.
Frequently asked questions
Can I swap a B22 holder for an E27 holder?
Yes, but it requires rewiring. The two types are not cross-compatible without changing the actual holder. You will need to follow safety precautions or consider hiring an electrician.
Do I need a special globe holder for LED bulbs?
Most LED bulbs are made to fit standard holders like B22, E27 or GU10. Make sure the holder is heat-resistant and that the voltage and wattage match.
Are ceramic globe holders better than plastic ones?
Ceramic holders handle heat better, making them suitable for high-use lights or enclosed spaces. They can suit ceiling downlights and kitchen installations when the fitting allows them.
What is a GU10 holder used for?
GU10 holders are used with GU10 bulbs, mainly for downlights in kitchens, bathrooms or hallways. They use a secure twist-lock system.
Can I use globe holders outdoors?
Yes, but the holder and complete fitting must have the appropriate IP rating for the location. Check the product label before installation and do not treat a covered position as fully weatherproof.
Need a different backup option during an outage? Our solar lighting kits cover a separate use case from fixed globe holders, but they can be useful where rewiring is not practical.
