E27 LED Light Bulbs for Every Edison Screw Fitting

The E27 socket uses a 27mm-diameter threaded base and is the most common bulb fitting in Australian homes. It is found in pendant lights, bedside lamps, floor lamps, wall sconces, table lamps, and a wide range of ceiling fittings. If you are unsure whether your fitting is E27 or the smaller E14, check the diameter of the threaded base: a 27mm thread is E27.

The GLS range forms the everyday core of the collection: clear and frost finishes from 6.5W to 11W across 2700K warm white, 3000K soft white, and 4000K natural white. For a warmer result, the 4W vintage GLS at 2000K and the 6.5W at 2200K suit dining tables and bedside pendants where the quality of the light matters more than output.

The globe range covers G80, G95, and G125 for open pendant fittings where the bulb is part of the look. Candle and fancy round bulbs suit chandeliers and wall sconces with narrow socket clusters. Tubular shapes suit bar pendants and industrial-style fittings.

The Sunset Dim series is available in GLS, candle, and Edison ST64 profiles. It produces 2700K at full brightness and shifts automatically to 1800K as the dimmer drops, with no app or smart system required.

Buying Guide

How do I know if I have an E27 fitting?

The E27 is identified by a 27mm diameter threaded base. It is the standard large Edison Screw fitting used across most Australian domestic pendants, floor lamps, table lamps, and wall sconces. The smaller Edison Screw size is E14, with a 14mm diameter thread, and is common in candelabra-style fittings, smaller decorative pendants, and some European-designed wall sconces. If your existing bulb has a screw base roughly the width of a standard wine cork, it is almost certainly an E27 bulb. If it is noticeably smaller, closer to the width of a pencil eraser, it is likely E14. When in doubt, remove the old bulb and measure the thread diameter, or check the fitting’s specification label.

Which bulb shape suits my fitting?

The GLS is the standard household shape and fits almost any E27 fitting: pendants, floor lamps, table lamps, and ceiling roses with a shade or diffuser. The globe shapes G80, G95, and G125 suit open pendant fittings and bare-socket installations where the bulb's shape is visible and part of the design. Candle and fancy round bulbs suit multi-arm fittings, chandeliers, and wall sconces where the fitting has a narrow socket, and the bulb extends beyond it into a visible position. Tubular shapes suit bar-style pendants and industrial fittings where a narrower, elongated profile is needed. The Edison ST64 suits vintage-style pendant fittings and open-socket cord sets, where the teardrop shape adds a decorative element.

What colour temperature should I choose?

Colour temperature determines how warm or cool the light appears. For bedrooms, dining rooms, and living rooms where a warm, settled atmosphere is the goal, the 2700K warm white range is the most practical choice, and the 2000K ultra warm and 2200K extra warm variants suit lamps and pendants that are purely atmospheric. For kitchens, home offices, and task-focused spaces, 3000K soft white or 4000K natural white provide a cleaner quality of light without reading as cold. If your room needs to move between a working state and an atmospheric one over the course of a day, the Sunset Dim series starts at 2700K at full brightness and automatically transitions toward 1800K at low dim as the dimmer drops.

Are all E27 bulbs in this collection dimmable?

The majority of the range is dimmable and compatible with most trailing-edge LED dimmers, including all dimmers sold by Dulora. The 3W GLS shatterproof is non-dimmable, and low-voltage 12V and 24V products use 1-10V or PWM dimming rather than the trailing-edge mechanism used by 240V mains products. For smooth, flicker-free dimming, confirm the dimmer is trailing-edge compatible and that the total load wattage is within the dimmer’s rated range. Product pages list the dimming specification for each globe, and Dulora’s dimmer range is designed to pair with the 240V bulbs in this collection.

Frequently Asked Questions

E27 LED Light Bulbs

• What is the difference between E27 and ES?
• ES stands for Edison Screw and refers to the same fitting as E27. The two terms are interchangeable in the Australian market: E27 is the international standard notation, and ES is the abbreviation commonly used in Australian trade and retail contexts. Both describe a screw-in bulb with a 27mm diameter threaded base.
• Can I use an E27 bulb in a B22 bayonet fitting?
• No. E27 is a screw fitting, and B22 is a bayonet fitting; they are not interchangeable without an adaptor. Dulora’s B22 range is available at the B22 LED Light Bulbs collection.
• Do these bulbs require a transformer?
• The 240V mains products in this range plug directly into a standard Australian E27 fitting with no transformer required. The 12V DC and 24V DC products require a compatible low-voltage transformer or driver, suited to off-grid, marine, caravan, and low-voltage circuit installations. The voltage for each product is listed on its product page.
• What warranty applies to these bulbs?
• Most bulbs in this collection carry a three-year warranty, with some variants carrying a two-year warranty. The warranty period for each product is stated on its individual product page.
