When shopping for LED light bulbs, you may come across terms such as A60, A19, E27, E26, G45, G120, and GU10. For buyers who are not familiar with lighting terminology, these codes can be confusing.
So, what does A60 bulb mean?
An A60 bulb is a standard A-shaped light bulb with an approximate maximum diameter of 60 mm. The letter “A” refers to the traditional bulb shape, while “60” refers to its approximate diameter in millimetres.
Importantly, A60 and E27 describe different parts of a lamp:
●A60 describes the bulb's shape and approximate diameter.
●E27 describes the screw-type lamp base.
●LED describes the light source technology.
●Wattage describes electrical power consumption.
●Lumens describe the amount of visible light produced.
This distinction is particularly important when selecting LED bulbs for residential, commercial, hospitality, and general lighting applications.
The term A60 can be understood in two parts:
A = A-shaped bulb
60 = approximately 60 mm bulb diameter
An A-shaped bulb has the familiar rounded form traditionally associated with general-purpose household light bulbs.
In practical terms, an A60 LED bulb normally has a bulb diameter of around 60 mm. Commercial products may have slightly different overall heights depending on the housing, diffuser, LED design, and lamp base.
An A60 LED bulb typically has an approximate maximum diameter of 60 mm, although exact dimensions can vary by product design.
A60 LED products with a 60 mm diameter, demonstrating that A60 is used as a recognized lamp form factor in commercial product specifications.
One of the most common misunderstandings is thinking that A60 means a 60W bulb.
It does not.
The “60” in A60 refers to the approximate bulb diameter, not power consumption.
For example:
Specification | Meaning |
A60 | Bulb shape and approximate diameter |
E27 | Screw lamp base |
8W | Actual LED power consumption |
800 lm | Approximate light output |
3000K | Warm white colour temperature |
CRI ≥80 | Colour rendering performance |
An A60 LED bulb could consume 6W, 8W, 10W, or another wattage depending on its design and performance.
This is probably the most important distinction for buyers.
A60 and E27 are not interchangeable terms.
They describe different characteristics of a lamp.
A60 tells you approximately what the glass/plastic bulb looks like and how wide it is.
E27 identifies the 27 mm Edison screw-type cap used to connect the lamp electrically and mechanically to the lampholder.
IEC standards cover lamp caps and their interchangeability requirements, including E27 lamp caps.
Therefore, a product can be described as:
A60 E27 LED Bulb
This means:
A60 shape + E27 screw base + LED light source.
This combination is extremely common in general lighting applications.
A60 and A19 refer to closely related A-shaped bulb formats, but the terminology is commonly used differently in different markets.
A60 is the metric designation commonly encountered in Europe and many international markets, while A19 is commonly used in North America.
Both describe the familiar general-purpose A-shaped bulb family, but their dimensional conventions differ.
For European B2B buyers, A60 E27 LED bulb is therefore a particularly useful search and product description format.
Interestingly, some international product specifications may list both A60 and A19 terminology depending on the target market.
For exporters and lighting distributors, this is a good reason to consider both market terminology and local search behavior when preparing product catalogs and online listings.
The A60 format is widely used because it provides a familiar general-purpose bulb shape suitable for many standard lighting fixtures.
Typical applications include:
●Residential lighting
●Hotels and hospitality
●Restaurants and cafés
●Offices
●Retail stores
●Corridors and common areas
●Apartments
●Decorative luminaires
●General-purpose replacement lighting
For B2B buyers, the main advantage is not simply the shape itself. The value comes from combining the appropriate base, wattage, lumen output, colour temperature, beam distribution, and product compliance for the intended application.
If you are sourcing A60 LED bulbs for a project or distribution business, don't select a product based only on the words “A60 LED bulb”.
There are several specifications to check.
First confirm the required fitting.
The most common European combination is:
A60 + E27
However, other base configurations may exist.
Always check the existing luminaire or lampholder before placing a bulk order.
Wattage tells you how much electrical power the lamp consumes.
Lumens tell you how much light it produces.
This is especially important when replacing conventional incandescent lamps with LED technology.
For example, an LED bulb using significantly less electrical power can provide a similar amount of useful light compared with an older incandescent lamp.
As an example, an A60 LED product with 7W power and 806 lumens, while identifying the conventional-lamp equivalent separately.
For professional procurement, compare:
Wattage → Lumens → efficacy (lm/W)
rather than wattage alone.
Common LED colour temperatures include:
CCT | Typical appearance | Common applications |
2700K | Warm white | Residential, hospitality |
3000K | Warm white | Hotels, restaurants, residential |
4000K | Neutral white | Offices, retail, commercial |
5000K+ | Cool/daylight | Functional and specialist applications |
The correct CCT depends on the atmosphere and visual requirements of the project.
For commercial buyers, offering multiple CCT options can make the same basic A60 platform suitable for different customer segments.
The A60 shape was originally associated with traditional incandescent lamps, but today the same familiar form factor is widely used for LED products.
The important difference is the light source technology.
A modern A60 LED bulb can provide:
●Lower power consumption
●Longer operating life
●Instant or near-instant light output
●Different colour temperatures
●Different lumen outputs
●Optional dimming
●Filament or opaque diffuser designs
●Different energy-efficiency levels
Therefore, A60 does not describe whether a bulb is LED or incandescent.
It describes the bulb form factor.
Buyers sometimes confuse A60 with other common decorative bulb shapes.
The main difference is physical form.
Bulb type | General form | Typical use |
A60 | Standard A-shaped bulb | General lighting |
G45 | Small globe | Decorative/general lighting |
G120 | Large globe | Decorative lighting, pendant fixtures |
Candle | Candle-shaped | Chandeliers, decorative fixtures |
PAR | Reflector-shaped | Directional lighting |
For example, SNORDER's G120 LED bulb range belongs to a different bulb form factor from an A60 bulb.
That distinction is useful when building a professional LED lighting portfolio: A60 is generally positioned as a standard general-purpose bulb, while larger G-series lamps can be used when a more prominent decorative appearance is required.
For wholesalers, distributors, contractors, and project buyers, the most important specifications go beyond bulb shape.
Before purchasing, check:
●Rated power
●Input voltage
●Frequency
●Power factor
●Operating current
●Dimmable or non-dimmable
●Luminous flux
●Colour temperature
●CRI
●Beam angle
●Colour consistency
●Luminous efficacy
●Bulb diameter
●Overall height
●Base type
●Housing material
●Diffuser material
For the European market, buyers should also verify the applicable regulatory and product-compliance documentation for the specific product.
Depending on the product and market, documentation may include relevant declarations, test reports, technical files, and applicable European compliance information.
For a B2B supplier, these documents are important because distributors and professional buyers often need more than a product photograph and a wattage specification.
For European distributors and lighting wholesalers, A60 E27 LED bulbs can be an effective general-purpose product category because the format is familiar and suitable for a wide range of luminaires.
However, successful sourcing is not simply about finding the lowest unit price.
Professional buyers should evaluate:
Product specification + consistency + documentation + packaging + MOQ + lead time + quality control + after-sales support
This becomes particularly important for importers purchasing hundreds or thousands of units.
A supplier should be able to provide clear technical specifications and support customers in selecting the appropriate configuration for different applications.
As an LED lighting supplier serving international B2B customers, SNORDER provides a range of LED bulb formats for different fixture types, lighting applications, and project requirements.
Our LED bulb portfolio includes E27 LED bulbs, LED filament bulbs, globe LED bulbs, AR111 LED bulbs, and other general-purpose and decorative lighting products. Different bulb shapes and housing designs can influence the appearance of the luminaire, light distribution, and overall lighting effect, so selecting the right form factor is an important part of LED bulb sourcing.
For applications where the bulb itself is visible, transparent or clear LED filament bulbs can provide a more decorative appearance while maintaining the functionality of an LED light source. SNORDER's LED filament range includes multiple shapes with E27 bases, such as A60, T64, G45, and G125. The E27 base is widely used in European residential and commercial lighting, making it a practical option for many standard fixtures.
For example, an E27 G120 LED bulb can be considered when a larger globe appearance is preferred over the more conventional A60 shape. In contrast, A60 LED bulbs are commonly selected for general-purpose lighting where a familiar standard bulb profile is required. G45 bulbs are suitable for more compact decorative fixtures, while AR111 LED bulbs are designed for applications requiring a directional beam and a different fixture format.
For B2B buyers, the choice between A60, G45, G120, AR111, and other LED bulb formats should not be based on bulb shape alone. Key factors include lamp holder type, bulb dimensions, input voltage, wattage, lumen output, color temperature, beam angle, dimming requirements, fixture compatibility, and the intended lighting application.
SNORDER can help buyers evaluate these specifications and select suitable LED bulb formats according to fixture requirements, application conditions, target market, and project needs.
SNORDER can help B2B buyers compare:
●Bulb shape
●Base type
●Texture type
●Wattage
●Lumen output
●CCT
●CRI
●Beam angle
●Product dimensions
●Packaging
●Compliance documentation
●MOQ and supply requirements

No.
A60 describes the bulb shape and approximate diameter, while E27 describes the screw base.
A product can therefore be both an A60 bulb and an E27 bulb.
No.
The number 60 refers approximately to the bulb diameter in millimetres, not its power consumption.
Not necessarily.
A60 describes the form factor. The bulb can use different light-source technologies, although A60 LED bulbs are now widely available.
An A60 bulb has an approximate maximum diameter of 60 mm. Actual overall dimensions can vary depending on the specific product design.
E27 is a very common combination, so buyers will frequently see products described as A60 E27 LED bulbs.
A60 is a standard A-shaped bulb format with an approximately 60 mm diameter.
G120 is a substantially larger globe-shaped bulb, generally used where a larger decorative appearance is desired.
For B2B purchasing, check base type, voltage, wattage, lumens, efficacy, CCT, CRI, dimensions, lifetime, dimming requirements, compliance documentation, MOQ, packaging, and supply consistency.
So, what does A60 bulb mean?
The simplest answer is:
A60 is a designation for a standard A-shaped bulb with an approximate diameter of 60 mm.
The “A” refers to the bulb shape, while the “60” refers approximately to its diameter in millimetres.
It does not mean 60 watts, and it does not specify the lamp base.
When you see A60 E27 LED bulb, you can read it as:
A60 = bulb shape
E27 = screw base
LED = light source technology
For professional lighting procurement, however, these are only the starting specifications. Lumens, efficacy, CCT, CRI, electrical performance, compliance documentation, dimensions, and supply capability should all be considered before selecting a product.
For B2B buyers evaluating different LED bulb formats, SNORDER can help match the appropriate bulb type to the application, fixture, and target market.
