G4 LED Bulbs
The G4 LED bulbs come as an energy-efficient version of the G4 halogen capsule bulbs. The G4 LED bulb uses up to 88% less energy to achieve the same light intensity as the conventional halogen bulbs. This difference is something you’ll certainly notice in your energy costs. The G4 LED bulbs are known for their very compact size and therefore fit in small fixtures. When purchasing G4 LED bulbs, it is important to look at two things. For example, some G4 LED bulbs work with 12V. This means you’ll need a transformer for it to work properly. In addition, it is always good to check the dimensions of your fixture when you are buying this bulb as replacement for your current G4 bulb.
The colour code is a combination of colour rendering (CRI) and light colour (Kelvin). The first number indicates the colour rendering (1 = very poor colour rendering, 9 = maximum colour fastness). The second and third number contains the light colour. Example: the colour code 830 consists of good colour rendering (8) and warm white light (3000K).
Every bulb or fixture has an energy efficiency class A to G. Energy label A is the most efficient and G the least. LED lighting is the most sustainable lighting technique. Even if a LED bulb is rated E or lower, they still save 70% of energy compared to conventional lighting with the same energy label. Why is it the same label then? To motivate LED brands to get even more durable.

G4 LED light bulbs are compact, energy-efficient alternatives to traditional halogen capsule bulbs. They’re perfect for small luminaires where space is limited, such as under-cabinet lighting, furniture lights, display cases, and decorative fittings. Despite their small size, G4 LEDs offer impressive brightness and long lifespan, making them a reliable choice for both commercial and residential applications.
Available in multiple wattages and light outputs, G4 LED capsules run on low voltage (typically 12V) and require a compatible LED transformer. These bulbs use a bi-pin (2-pin) base, spaced 4mm apart, which fits easily into many common low-voltage fittings.
Looking for flexibility in light control? Our range includes dimmable G4 LED light bulbs, allowing you to adjust the brightness to suit the mood or task. Dimmable options are particularly useful in hospitality settings, kitchen installations, or bespoke furniture designs where lighting ambiance is key. Always ensure that the LED driver and dimmer switch used are compatible with LED technology to avoid flickering or reduced bulb life.
Why switch to G4 LED?
Compared to traditional halogen capsules, G4 LEDs use up to 90% less energy and last significantly longer – reducing both electricity costs and maintenance time. They also emit less heat, making them safer and more suitable for enclosed or sensitive installations.
Buying tips:
- Check if your application uses 12V AC or DC – match your bulb and transformer accordingly.
- For mood lighting or decorative installations, select dimmable G4 LED light bulbs.
- Choose warm white (2700K–3000K) for cosy environments or cool white (4000K+) for task lighting.
- Ensure compatibility with existing fixtures, especially in older setups previously fitted with halogen
What are the benefits of G4 LED light bulbs?
G4 LED light bulbs are energy-efficient, compact, and long-lasting, making them ideal for small fittings like cabinet lights, display units, and decorative fixtures.
Are dimmable G4 LED light bulbs compatible with all dimmers?
No, they require an LED-compatible dimmer switch and transformer. Always check for compatibility to avoid flickering or premature failure.
Can I replace a halogen G4 bulb with a G4 LED directly?
Yes, but ensure the transformer is compatible with LED bulbs. Older halogen drivers may not work correctly with low-wattage LEDs.
Do G4 LED bulbs run on mains power?
No, G4 LEDs typically operate on 12V and need a low-voltage LED driver or transformer.
