LED Lightbulbs explained

LED Lightbulbs explained

When people think about improving the energy efficiency of their home lighting, they often assume it means replacing fittings with recessed downlights.

But that isn’t the case.

One of the simplest and most effective upgrades you can make is simply switching your lightbulbs to LED.

This means you can keep the beautiful lighting you already love—pendants, table lamps, floor lamps, wall lights, and chandeliers—while still dramatically reducing energy use.

Why Choose LED Lightbulbs?

LED lighting has completely changed how we light our homes. It allows you to enjoy warm, decorative, and functional lighting while being far more efficient than traditional bulbs.

Use up to 90% less power

LED bulbs use only a fraction of the electricity of traditional incandescent bulbs, helping reduce energy bills.

Last much longer

A good quality LED bulb can last up to 15 times longer, meaning fewer replacements and less maintenance.

Instant light

No warm-up time—LED bulbs reach full brightness immediately.

Less heat

LEDs waste far less energy as heat, making them safer and more efficient.

Dimmable options available

Many LED bulbs can be used with compatible dimmers, allowing you to adjust the mood and brightness of a room.

Understanding LED Wattage

One of the most common questions is how LED wattage compares to traditional bulbs.

With LEDs, wattage measures energy use—not brightness.

As a general guide, LED bulbs use around one-tenth of the power of a traditional incandescent bulb while producing a similar light output.

A simple guide:

Traditional Bulb	LED Equivalent	Typical Brightness (Lumens)
40W	4–5W LED	~400–470 lm
60W	6–8W LED	~700–800 lm
75W	8–10W LED	~1100–1200 lm
100W	10–15W LED	~1500–1600 lm

For example, a 10W LED can produce a similar amount of light to a traditional 100W bulb, while using a fraction of the electricity.

When choosing LED bulbs, it’s often best to think in terms of brightness (lumens) rather than wattage alone. Lumens simply tell you how much light you’ll get.

Traditional Bulb	LED Equivalent
40W	4–5W LED
60W	6–8W LED
75W	8–10W LED
100W	10–15W LED

For example, a 10W LED bulb can produce a similar amount of light to a 100W traditional bulb, while using a fraction of the electricity.

When choosing LED bulbs, it’s often better to look at lumens rather than wattage, as lumens measure brightness more accurately.

As a rough guide, higher lumens = brighter light, regardless of wattage.

LEDs Come in Many Shapes and Styles

One of the biggest advantages of modern LED lighting is the variety available.

You don’t need to compromise the look of your lighting to be energy efficient.

LED bulbs now come in many shapes, including:

• Candle bulbs
• Golfball bulbs
• GLS standard bulbs
• Globe bulbs
• Tubular bulbs
• Filament-style decorative bulbs
• Reflector bulbs

This means you can maintain the style of your fittings while upgrading the performance inside them.

Choosing the Right Colour Temperature

LED bulbs are available in different colour temperatures, allowing you to set the mood of a space.

Warm White (2700K–3000K)

Soft and inviting—ideal for living rooms, bedrooms, and decorative lighting.

Cool White (4000K)

Clean and crisp—commonly used in kitchens, bathrooms, and work areas.

Daylight (5000K–6000K)

Bright and energising—best for task lighting, workshops, and commercial spaces.

Beautiful Lighting Doesn’t Need to Change

Good lighting is about atmosphere, style, and comfort—not just efficiency.

By switching to LED lightbulbs, you don’t need to replace your fittings or lose the character of your lighting. Instead, you can keep the pieces you love and simply upgrade what’s inside them.

Sometimes the most effective lighting change isn’t a new fitting—it’s simply the right bulb.
