Choosing the right LED light bulb starts with matching the socket and shape to your fitting, then selecting the color temperature that suits the space.

Most Australian homes and commercial spaces run on one of four sockets. E27 and B22 are the most common, found in pendant lights, table lamps, and ceiling fittings across the country. E14 and B15 suit smaller decorative fittings: chandeliers, wall sconces, and compact pendants where a full-size base will not fit.

Within each socket, shape determines how the light falls. A GLS or frosted globe distributes light evenly in all directions, ideal for enclosed fittings and table lamps. A candle or flame-tip bulb concentrates the beam upward, built for chandeliers and multi-arm pendants where the silhouette matters. Edison and ST64 shapes suit industrial and vintage-style pendants. Oversized G95 and G125 globes make a deliberate statement when the fitting is on display.

Color temperature sets the mood. Ultra warm at 2000K reads closer to candlelight and suits decorative and ambient settings. Extra warm at 2200K brings a rich, golden tone to living rooms and dining spaces. Warm white at 2700K is the most widely used residential choice. Soft white at 3000K suits kitchens and bathrooms where warmth meets task brightness. Natural white at 4000K delivers a clean, crisp tone suited to workspaces and commercial environments. All Dulora LED light bulbs are SAA certified, carry up to three years warranty, and are rated by thousands of verified Australian customers.

What socket do I need: E27, E14, E12, B22, or B15?

The socket in your fitting determines which bulb you buy, not the other way around. E27 and B22 are the two most common in Australian homes. E27 is a large screw base found in most pendants, floor lamps, and table lamps; B22 is a large bayonet cap found in most ceiling fittings and batten holders. E14 and B15 are smaller versions of each: E14 suits chandeliers, wall sconces, and decorative pendants; B15 suits compact decorative fittings that require a smaller bayonet base. E12 mini Edison screw is a candelabra base that turns up in imported fittings and specialist decorative pendants in our range. To identify your socket, remove the existing bulb and look at the base. A screw thread means an Edison screw (E27, E14, or E12). Two small pins and a twist-lock mean a bayonet cap (B22 or B15).

What shape should I choose?

Shape affects both how the light spreads and how the bulb looks in the fitting. For enclosed fittings, table lamps, and ceiling pendants with shades, a GLS or frosted globe is the practical choice: it distributes light evenly without hotspots or glare. For open pendants and exposed fittings where the bulb is on display, shape becomes part of the design. Candle and flame-tip bulbs bring a traditional silhouette to chandeliers and multi-arm pendants; browse Dulora's candle bulb range. Edison and vintage styles suit industrial and warehouse-style spaces. Oversized G95 and G125 globes work best in large, feature pendants where the fitting is meant to be seen. For narrow fittings where a standard bulb will not fit, Dulora's tubular range offers a practical solution.

What color temperature is right for each room?

Color temperature is measured in Kelvin (K) and controls whether the light reads as warm and intimate or bright and functional. Ultra warm at 2000K reads closest to candlelight and suits decorative pendants and ambient settings where mood is the priority. Extra warm at 2200K brings a rich golden tone to living rooms and dining spaces. Warm white at 2700K is the most widely used choice across Australian bedrooms, living areas, and dining rooms. Soft white at 3000K balances warmth with clarity and suits kitchens and bathrooms. Natural white at 4000K delivers a clean, crisp tone for workspaces and commercial environments. Color temperature stays constant as you dim a standard LED. For a halogen-style warm shift as you dim, where the light shifts gradually from 2700K down to 1800K as you lower the brightness, our dim-to-warm range is built for that effect.

What is the difference between dimmable and non-dimmable LED bulbs?

A dimmable LED bulb contains circuitry that works with a compatible dimmer switch to reduce light output smoothly, rather than cutting power directly. Non-dimmable bulbs are not designed for this and will typically flicker, buzz, or fail early if used on a dimmer circuit. Dimmable bulbs can be used in any standard non-dimmable fitting at full brightness with no issue: the dimmable rating indicates capability, not a requirement. If you are fitting bulbs in a home where dimmer switches are already installed or planned, choosing dimmable bulbs throughout is the practical approach. Dulora's dimmable LED bulbs work with most incandescent and LED dimmers; every dimmer Dulora sells is trailing-edge. Browse the full dimmable range, and compatible dimmer switches.

Frequently Asked Questions: LED Light Bulbs

• Do I need a dimmer switch to use dimmable LED bulbs?
• No. A dimmable LED bulb works in any standard non-dimmable fitting at full brightness with no performance penalty. The dimmable rating means the bulb is capable of working with a dimmer switch, not that it requires one. If your fitting is on a dimmer circuit, dimmable LED bulbs work with most incandescent and LED dimmers. Every dimmer Dulora sells is trailing-edge and compatible with our dimmable LED range. Visit our full range of compatible dimmer switches, and the complete dimmable LED bulb collection.
• How do I know which socket fits my fitting?
• Remove the existing bulb and check the base. Most bulbs have the code printed on the base or the glass, which is the fastest way to find it. If it has worn off, the shape tells you the type: a screw thread means an Edison screw, and two small pins with a twist-lock mean a bayonet cap. The number in each code is the base diameter in millimetres, so E27 measures 27 mm, E14 measures 14mm, B22 measures 22mm, and B15 measures 15mm. E27 and B22 are the most widely used in Australian homes, with E14 and B15 found in chandeliers, wall sconces and smaller decorative fittings. E12 also appears in some decorative and imported fittings, and because it sits only 2mm below E14, the two are easy to confuse, so check the printed code rather than judging by eye.
• Are Dulora LED light bulbs SAA certified?
• Yes. All Dulora LED light bulbs carry SAA certification, confirming they meet Australian and New Zealand safety and performance standards. SAA certification is a legal requirement for electrical products sold in Australia and ensures the bulb is safe for use in Australian residential and commercial fittings.
• What CRI do Dulora LED light bulbs have?
• Dulora LED light bulbs are available across a range of CRI ratings depending on the product, with specifications listed in each product's specification table. A higher CRI value means colors in the room appear more accurate and vivid under the light. CRI stays consistent whether the bulb is at full brightness or dimmed.
• What warranty do Dulora LED light bulbs carry, and how long do they last?
• Dulora LED light bulbs carry up to three years warranty covering defects in materials and workmanship. Rated lifespan varies by product; see each product's specification table for the exact figure. All bulbs are SAA certified and meet Australian and New Zealand safety standards. If a bulb fails within the warranty period, contact Dulora's customer support team directly for a replacement.
