Capsule LED Bulbs for Compact and Decorative Fittings

The capsule globe is defined by its compact bi-pin base and sealed body, designed for fittings where space is restricted and a standard screw or bayonet bulb simply will not fit. The G9 and G4 are the two most common bi-pin capsule types: the G9 runs on 240V mains power and suits a broad range of ceiling fittings, wall sconces, under-cabinet lights, and display applications, while the G4 operates on low-voltage 12V and 24V DC systems suited to marine, caravan, and landscape lighting installations.

Dulora's G9 capsule range comes in clear and frosted finishes. The clear finish allows the LED to be fully visible, giving a defined light point suited to open fittings and display applications. The frosted finish diffuses the output, reducing glare and producing a softer, more even glow suited to enclosed fittings and task-adjacent applications. Colour temperatures span extra warm 2200K, warm white 2700K, and soft white 3000K, covering the full warm-to-neutral range that most ceiling and wall fittings require.

All 240V G9 products are SAA-certified, dimmable, and flicker-free. G4 and low-voltage G9 models are also dimmable on compatible 12V and 24V DC dimmers; check the product page for compatible dimmer specifications. All products deliver high CRI colour accuracy and are covered by a warranty of up to 3 years. Free metro delivery on orders over $99, free regional delivery over $199.

Buying Guide

What is the difference between G9 and G4?

G9 and G4 both describe bi-pin capsule globes but they run on different voltages and suit different applications. The G9 has two parallel pins spaced 9mm apart and runs on standard 240V mains power, making it compatible with most ceiling fittings, wall sconces, and under-cabinet lights in Australian homes. The G4 has two pins spaced 4mm apart and runs on low-voltage 12V or 24V DC, suited to marine, caravan, landscape, and display installations where mains power is not available or not appropriate. The two sockets are not interchangeable: check your fitting specifications or your existing globe before ordering.

Which colour temperature suits a capsule globe?

Extra warm 2200K gives the deepest amber tone, suited to feature wall lights and dining room fittings where atmosphere takes priority over task output. Warm white 2700K is the most widely used temperature in the G9 range and works well across ceiling fittings, under-cabinet lights, and display applications where warmth is wanted with good visibility. Soft white 3000K is a cooler, more neutral warm tone suited to kitchen and bathroom fittings where clarity matters. The 3W G9 Frost covers all three colour temperatures in a single product, making it a versatile choice for fittings where the exact temperature may need to change.

Can I dim capsule LED bulbs?

All capsule LED bulbs in this collection are dimmable. The 240V G9 models work with most incandescent and LED dimmers, and low-voltage G4 and G9 models require a compatible 12V or 24V DC dimmer controller. Dulora-sold dimmers are trailing-edge, which is the correct driver type for LED loads. In ceiling fittings, wall sconces, and under-cabinet lights where G9 capsules are most commonly used, dimming controls the mood and function of the space across the full brightness range. Browse our dimmers collection for compatible trailing-edge options. Check the product page to confirm dimming compatibility for your specific globe-dimmer combination.

Why does colour accuracy matter for capsule globes?

Capsule globes are used in fittings where the light falls at close range: G9 ceiling fittings, wall sconces, and under-cabinet lights are all applications where the quality of the light is more visible than in a larger, more diffuse installation. A globe with high colour accuracy renders fabrics, wall finishes, and decorative surfaces the way they appear under natural light, rather than shifting their tone. For fittings that form part of a styled interior, this makes a genuine difference. All G9 and G4 capsule globes in this collection carry high colour accuracy; check the specification table on each product page for the exact CRI figure. Note that high colour accuracy is not the same as full-spectrum lighting: it means colours render accurately under the light, not that the light contains every wavelength of the visible spectrum.

Where are capsule LED bulbs most commonly used?

G9 capsule globes are specified wherever a compact 240V bi-pin fitting is required: ceiling light fittings, wall sconces, under-cabinet lighting, display cabinets, and bathroom vanity mirrors all commonly use the G9 socket. The small profile makes the G9 particularly well suited to enclosed or recessed fittings where a standard globe would not fit. G4 capsule globes are used in low-voltage applications: marine and caravan lighting, landscape and garden fittings, decorative accent lighting, and any 12V or 24V DC installation where compact output is needed.

Frequently Asked Questions

Capsule LED Bulbs

• What wattage do these capsule LED bulbs replace?
• The 2W G9 models replace a 25W halogen and the 3W and 5W models replace a 40W halogen. G4 models vary by product; exact equivalent ratings are listed on each product page in the specification table.
• Are capsule LED bulbs dimmable?
• All models in this collection are dimmable; 240V G9 models work with most incandescent and LED dimmers using trailing-edge drivers, while low-voltage G4 and G9 models require a compatible 12V or 24V DC dimmer controller. Check the product page to confirm dimming compatibility for your specific globe and fitting.
• What is the CRI rating for these globes?
• All G9 and G4 capsule globes in this collection are rated CRI90. CRI ratings are listed in the specification table on each product page. A high CRI is not the same as full-spectrum lighting; CRI90 means colours render accurately under the light across 90 percent of the visible spectrum.
• What is a G9 capsule bulb?
• G9 describes the bi-pin base of the globe: two parallel pins spaced 9mm apart. The G9 is the standard 240V bi-pin socket used in compact ceiling fittings, wall sconces, and under-cabinet lights. It is not a screw or bayonet fitting and requires a matching G9 socket in the fitting.
