Halogen Transformers

Reliable 12V Halogen Transformers for New and Replacement Installations

A halogen transformer safely converts the 230V mains supply into a 12V low-voltage output for halogen lighting. Although LED lighting has become the standard, 12V halogen lamps are still widely used in homes, retail stores, hospitality environments and renovation projects where existing halogen fixtures remain in service.

Tradim offers high-quality electronic halogen transformers designed for both new installations and the replacement of existing transformers. With their compact design, comprehensive protection features and compatibility with dimmable installations, our transformers provide a reliable and long-lasting solution for a wide range of lighting applications.

Why Choose an Electronic Halogen Transformer?

Electronic halogen transformers are smaller, lighter and more efficient than traditional wire-wound transformers. By using high-frequency electronic technology, they offer a compact design that can easily be concealed above ceilings, inside luminaires or in suspended ceiling systems.

Modern electronic transformers also include several built-in protection features that help extend the service life of both the transformer and the connected halogen lamps.

Benefits of an Electronic Halogen Transformer

• Compact and lightweight design
• High efficiency
• Suitable for dimmable halogen lighting
• Soft Start extends lamp life
• Thermal protection
• Short-circuit protection
• Overload protection

Applications

Our halogen transformers are specifically designed for 12V low-voltage halogen lighting and are commonly used for:

• Recessed spotlights
• Surface-mounted spotlights
• Ceiling lighting
• Cabinet lighting
• Kitchen lighting
• Display lighting
• Retail lighting
• Hospitality lighting
• Commercial and project lighting

These transformers are designed exclusively for low-voltage halogen lamps and should not be used with LED lighting.

Choosing the Right Halogen Transformer

The most important factor when selecting a halogen transformer is the total connected wattage.

Simply add the wattage of all connected halogen lamps and select a transformer whose operating range covers the total load.

Examples

• 3 × 20W = 60W → choose a 35–105W transformer.
• 5 × 35W = 175W → choose a 50–210W transformer.

Operating outside the specified minimum or maximum load may affect performance. Always ensure the total connected load falls within the recommended operating range.

Suitable for Dimmable Halogen Lighting

Most 12V halogen installations are combined with a dimmer. Tradim electronic halogen transformers are therefore designed to work with the most commonly used electronic halogen dimmers.

This provides smooth, stable dimming for comfortable and atmospheric lighting.

Soft Start Extends Lamp Life

A key advantage of Tradim halogen transformers is the integrated Soft Start function.

When switched on, the output voltage increases gradually rather than instantly. This reduces the inrush current and minimises stress on the halogen lamp filament.

The result is:

• Reduced lamp failures
• Longer lamp life
• Improved reliability
• Lower maintenance costs

Built for Safe Operation

A transformer is the heart of every low-voltage lighting installation. That is why Tradim electronic halogen transformers include multiple built-in protection features.

Depending on the model, these include:

• Thermal protection
• Short-circuit protection
• Overload protection

These safety features help protect both the transformer and the connected lighting installation while contributing to long-term reliability.

Round Halogen Transformers

Tradim supplies compact round electronic halogen transformers that are easy to install above suspended ceilings or inside lighting fixtures.

Their compact dimensions make them ideal for replacing existing transformers without modifying the installation.

Available power ranges include:

• 35–105W
• 50–210W

This provides a suitable solution for the vast majority of low-voltage halogen lighting installations.

Replacement for Popular Transformer Brands

Many existing halogen lighting systems still rely on transformers that eventually require replacement after years of service.

Tradim halogen transformers provide an excellent replacement for many well-known brands and models, including:

• Kaoyi
• Freetec
• Global Lux
• Calex
• Huibolong

This often allows existing lighting installations to be repaired without replacing luminaires or rewiring the installation.

With their compact design, advanced protection features and compatibility with dimmable halogen lighting, Tradim transformers provide a dependable solution for both renovation projects and replacement installations.

Frequently Asked Questions

Can I use a halogen transformer with LED lighting?

No. A halogen transformer is designed exclusively for 12V halogen lighting. For LED lighting, we recommend using a suitable dimmable LED driver.

How do I determine the required power rating?

Add together the wattage of all connected halogen lamps and select a transformer whose operating range includes the total connected load.

Are these transformers dimmable?

Yes. Tradim electronic halogen transformers are compatible with the most commonly used electronic halogen dimmers.

What does Soft Start do?

Soft Start gradually increases the output voltage when switching on. This reduces stress on the halogen lamp filament and typically extends lamp life.

Can I replace a Kaoyi transformer with a Tradim transformer?

Yes. Several Tradim halogen transformers are technically identical to well-known Kaoyi models and can often be used as direct replacements.
