LED vs Filament Bulbs: Which Light Globe Is Best for Your Home?

Choosing a light bulb should be simple, but labels such as LED, filament, E27, B22, 2700K and 6000K can quickly become confusing.

The most important fact is this:

LED describes the technology that produces the light. Filament often describes either an older incandescent bulb or the decorative appearance of a modern LED filament bulb.

A modern LED filament bulb is still an LED. It simply uses thin LED strips arranged to resemble the glowing wire inside a traditional incandescent globe. This gives you a more decorative, vintage appearance without returning to the high electricity consumption of old-fashioned incandescent lighting. Modern filament LED lamps are available in familiar shapes, bases and warm colour temperatures while retaining LED efficiency.

For most homes and businesses, the practical decision is therefore not simply “LED or filament”. It is usually:

 

Should you choose a standard LED bulb or a decorative LED filament bulb?

What Is a Standard LED Bulb?

A standard LED bulb normally contains LED chips beneath an opal or frosted diffuser. The diffuser softens the light, reduces visible glare and distributes illumination more evenly around a room.

Standard LED globes are generally the best choice when brightness, efficiency and everyday practicality matter more than the appearance of the bulb itself.

They work particularly well in:

• Ceiling fittings
• Bedrooms
• Kitchens
• Offices
• Garages
• Passageways
• Enclosed or partially enclosed shades
• Utility and work areas

South African energy-saving guidance recommends replacing inefficient incandescent globes with LEDs. Depending on the products being compared, the reduction in electricity consumption can be approximately 80% to 90%.

Recommended standard LED options

For fittings that use a bayonet connection, consider the LED Basic A60 B22 7W Opal 6000K. For screw-in fittings, the LED Basic A60 E27 7W Opal Bulb 6000K provides the same familiar A60 shape with an E27 base.

Whitehouse Lighting and Electrical’s current catalogue contains both E27 and B22 general-purpose LEDs alongside decorative candle, golf-ball, ST64 and G125 filament designs.

What Is an LED Filament Bulb?

An LED filament bulb uses narrow LED elements arranged inside a clear or amber glass envelope. These elements imitate the glowing filament seen inside traditional incandescent bulbs. The exposed design makes the bulb itself part of the décor.

LED filament globes are ideal for:

• Open pendant lights
• Chandeliers
• Bedside lamps
• Wall sconces
• Restaurants and cafés
• Reception areas
• Dining rooms
• Decorative table lamps
• Vintage, industrial and minimalist interiors

A filament bulb is especially effective when the fitting does not hide the globe. In an open cage pendant or clear glass shade, a plain opal bulb may appear bulky, while a clear ST64, candle or globe-shaped filament bulb contributes to the overall design.

Recommended decorative filament options

For chandeliers and smaller fittings, the Brightstar 4W E14 LED Filament Candle Bulb 2700K produces a warm 2700K light from a compact candle shape.

For vintage pendants, the Brightstar 6W ST64 Filament Bulb E27 2700K combines an elongated ST64 shape with warm ambient lighting.

For compact decorative fixtures, consider the WHL&E B3-05 4W G45 Filament Bulb E27 3000K.

For oversized open pendants and feature lighting, the WHL&E B3-10 6W G125 Filament Bulb E27 3000K creates a stronger visual focal point.

Which Uses Less Electricity?

Both standard LED and LED filament bulbs are highly energy-efficient.

The major electricity difference is between LED technology and traditional incandescent technology, not between standard LED and LED filament designs.

Consider this illustrative example:

• One traditional 60W incandescent bulb used for four hours per day consumes 87.6kWh per year.
• One 7W LED used for the same period consumes 10.22kWh per year.
• The LED saves approximately 77.38kWh per year per bulb, or about 88% of the electricity used by the 60W bulb.

The actual rand saving depends on your municipal or Eskom tariff, how many globes you replace and how long they operate each day.

When comparing products, do not choose a bulb based only on wattage. Watts measure electricity consumption. Lumens measure visible light output.

A lower-wattage bulb is only a suitable replacement when it provides enough lumens for the room.

E27, B22, E14 and GU10: Which Base Do You Need?

The bulb base must match the lamp holder. A bulb with the wrong base will not fit, regardless of its wattage, brightness or colour temperature.

E27: Standard screw-in bulb

E27 is a common Edison screw base. The bulb is installed by turning it clockwise into the holder.

E27 is widely used in:

• Pendant lights
• Table lamps
• Floor lamps
• Decorative fixtures
• Modern ceiling fittings

The “27” refers to the approximate diameter of the screw base in millimetres.

B22: Bayonet or clip-in bulb

B22 bulbs have two side pins. The bulb is inserted into the holder, pressed down and turned to lock it into place.

Customers commonly describe B22 as:

• Bayonet
• Clip-in
• Push-and-turn
• Pin-type globe

B22 is common in many established South African homes.

E14: Small screw-in bulb

E14 is a smaller Edison screw base commonly found in:

• Chandeliers
• Candle fittings
• Bedside lamps
• Decorative wall lights
• Small appliance lamps

An E14 bulb cannot be used in an E27 holder without an appropriate adaptor.

GU10: Downlight connection

GU10 bulbs have two short pins with widened ends. They are inserted and twisted into place.

GU10 is commonly used in:

• Recessed downlights
• Track lights
• Spotlights
• Directional ceiling fittings

Before ordering, remove the existing globe safely and check the code printed on its base or packaging.

A60, G45, ST64 and G125: Understanding Bulb Shapes

The letters and numbers on a bulb may also describe its shape and approximate diameter.

A60: A60 is the familiar household bulb shape. It works well for general lighting and fits inside most conventional lamp shades.

G45: G45 is a compact round golf-ball shape. It is suitable for smaller fittings, vanity lights, chandeliers and decorative lamps.

ST64: ST64 has an elongated vintage shape, often associated with Edison-style decorative lighting. It works particularly well in open pendants and industrial-style fittings.

G125: G125 is a large globe-shaped bulb designed to be visible. It creates a strong decorative feature in minimalist pendants, restaurants, reception areas and modern living spaces.

Candle bulb: Candle bulbs have a narrow, tapered profile. They are commonly used in chandeliers and traditional decorative fittings.

Always confirm that the bulb will physically fit inside the shade or enclosure. An E27 G125 bulb and an E27 A60 bulb use the same base, but the G125 bulb is considerably larger.

Warm White vs Cool White: Which Colour Temperature Is Best?

Warm White vs Cool White: Which Colour Temperature Is Best?
Colour temperature is measured in Kelvin, shown as K on the packaging.

South African consumer guidance identifies traditional warm incandescent light as generally falling between 2700K and 3000K. As the Kelvin value increases, the light appears cooler and more blue-white.

2700K to 3000K: Warm white

Warm white produces a soft, comfortable and slightly golden light.

Best for:

• Bedrooms
• Lounges
• Dining rooms
• Restaurants
• Hotels
• Decorative pendants
• Filament bulbs
• Relaxing spaces

Around 4000K: Neutral white

Neutral white provides a cleaner appearance without the intense blue-white effect of daylight globes.

Best for:

• Bathrooms
• Kitchens
• Home offices
• Retail areas
• General workspaces

6000K to 6500K: Daylight or cool white

Daylight white creates a crisp, high-visibility appearance.

Best for:

• Garages
• Workshops
• Kitchens
• Storerooms
• Security areas
• Offices
• Task lighting

Colour temperature does not tell you how bright a bulb is. A 3000K bulb and a 6000K bulb can produce the same number of lumens while creating very different atmospheres.

Are Filament Bulbs Bright Enough?

Yes, provided the lumen output suits the application.

Filament bulbs are often selected for ambience, but modern versions can still produce useful general illumination. For example, Whitehouse Lighting and Electrical’s catalogue includes a 4W E14 filament candle rated at 400 lumens and a 6W ST64 filament bulb rated at 600 lumens.

However, a single decorative bulb may not provide enough light for a large room.

For better results:

• Use multiple bulbs in chandeliers or multi-light pendants.
• Combine decorative pendants with downlights or wall lights.
• Use brighter task lighting over kitchen counters and desks.
• Treat decorative filament bulbs as part of a layered lighting plan.

Can LED Filament Bulbs Be Dimmed?

Only bulbs specifically marked dimmable should be connected to a dimmer.

A non-dimmable LED connected to a dimmer may:

• Flicker
• Buzz
• Switch off unexpectedly
• Have a restricted dimming range
• Fail prematurely

The dimmer must also be compatible with LED loads. Older dimmers designed for high-wattage incandescent bulbs may not work correctly with low-wattage LEDs.

For adjustable decorative lighting, consider a product such as the O-Lite G125 5W Dimmable E27 Filament Bulb.

When uncertain, ask a qualified electrician to confirm the compatibility of the bulb, dimmer and fitting.

Which Bulb Should You Choose?

Choose a standard opal LED bulb when:

• The bulb is hidden behind a shade.
• You need practical everyday lighting.
• Uniform light distribution matters.
• You want an economical replacement globe.
• The fitting is used for task lighting.

Choose an LED filament bulb when:

• The bulb will remain visible.
• The fitting forms part of the room’s décor.
• You want a warm, vintage or premium appearance.
• You are lighting a dining room, bedroom, restaurant or reception area.
• You are using an open pendant, chandelier or clear glass fitting.

Avoid traditional incandescent filament bulbs for routine household lighting. They use substantially more electricity and generate more heat than LED alternatives. South African authorities regulate general-service lamp efficiency and safety through compulsory specifications, while national energy guidance encourages the replacement of inefficient lighting with LEDs.

Light Bulb Buying Checklist

Before purchasing your next globe, check:

1. Base: E27, B22, E14, GU10 or another connection.
2. Shape: A60, G45, ST64, G125, candle or reflector.
3. Brightness: Compare lumens, not only watts.
4. Colour temperature: Warm, neutral or daylight white.
5. Dimming: Confirm that both the bulb and dimmer are compatible.
6. Fitting size: Ensure the bulb fits inside the shade.
7. Voltage: Select a product intended for the fitting and local supply.
8. Application: General, task, accent or decorative lighting.
9. Enclosure: Check whether the bulb is suitable for an enclosed fitting.
10. Product compliance: Buy electrical products from a reliable retailer and follow the manufacturer’s installation instructions.

Frequently Asked Questions (FAQ's)

1. Is an LED filament bulb a real LED?

Yes. It uses LED elements arranged to resemble a traditional glowing filament. The visible design changes the appearance of the bulb, but the light source remains LED technology.

2. Is B22 screw-in or clip-in?

B22 is a bayonet-style push-and-turn connection. E27 is the standard larger screw-in connection.

3. Is warm white or cool white better?

Warm white is usually better for bedrooms, lounges, dining rooms and decorative lighting. Neutral or cool white is generally preferred where visibility and concentration matter, such as kitchens, offices, garages and workspaces.

4. Can I replace a 60W bulb with a 7W LED?

Potentially, but compare lumen output rather than wattage alone. The replacement LED must provide enough brightness for the intended area.

5. Which bulb is best for a chandelier?

An E14 candle filament bulb is a common choice, but the correct base depends on the chandelier’s lamp holders. Check the fitting before ordering.

6. Which bulb is best for a pendant light?

For an open pendant, consider an E27 ST64 or G125 filament bulb. For a pendant with an enclosed or opaque shade, a standard A60 LED may provide more practical illumination.

7. Do LED bulbs get hot?

LEDs still produce heat, but substantially less than traditional incandescent bulbs. Heat must still be managed correctly, particularly in enclosed fittings.

Find the Right Globe for Your Space

The best light bulb is not simply the one with the highest wattage or the lowest price. It must match the fitting, produce the correct brightness, create the right atmosphere and operate efficiently. For practical everyday illumination, choose a standard LED globe in the correct E27 or B22 base. For exposed pendants, chandeliers and feature fittings, choose an LED filament bulb in a shape that complements the light fixture.
