The G12 metal halide lamp is an efficient lamp based on discharge technology, used for professional and industrial lighting. A power of 70 W achieves 6500 lm of light — significantly more than a halogen or old fluorescent lamp at the same power. The 3000 K color temperature provides a warm white tone, and the 360° light distribution spreads light in every direction. The UV-protected bulb ensures safe use in locations where the lighting is close to the objects being illuminated.

Requires a separate ballast. 85 V lamp voltage — NOT for direct 230 V mains voltage. G12 base. Installation by a qualified electrician.

Compatibility and installation

Ballast required — no direct mains connection

The metal halide lamp does NOT work directly on 230 V mains voltage. The lamp requires a separate ballast that:

  • Regulates the lamp's starting and operating voltage (the lamp operates at 85 V)
  • Provides a high starting voltage to ignite the lamp
  • Stabilizes the current during operation

The ballast can be magnetic (older, traditional choke + igniter) or electronic (modern HID driver — better control, less flickering). Check your luminaire's ballast before purchasing. An electrician will take care of choosing the correct type.

Applications

  • Industrial halls and warehouses
  • Sports halls and multi-purpose facilities
  • General lighting for commercial premises
  • High-ceiling lighting solutions
  • Outdoor locations where bright light is needed (in a suitably IP-rated luminaire)

Startup and shutdown time

A special feature of the metal halide lamp is its slow startup and shutdown:

  • Startup to full brightness: 1–4 minutes (from cold)
  • Restart after a short shutdown: 5–10 minutes waiting time

This limits the use of the lamp — it is not suitable for locations where light is needed immediately or where the lamp is switched on/off frequently. It is well-suited for locations where the light is on for the entire duration of opening hours or a work shift.

UV protection

A metal halide lamp inherently produces a significant amount of UV radiation. The UV-protected bulb filters out harmful UV. This is especially important in environments where people are close to the light or materials that can fade. Never use a metal halide lamp without a luminaire equipped with protective glass — even a UV-protected lamp requires a protective cover in the luminaire.

Service life

The typical service life of a metal halide lamp is 6,000–10,000 hours — significantly more than halogen but less than LED. For long-term use, LED is often a more reasonable long-term solution.

Usein kysytyt kysymykset

What is the difference between a metal halide lamp and an LED lamp?

Both offer effective lighting, but there are significant differences:

  • Metal halide lamp (this one): discharge technology, gas ionization. Slow startup, requires a ballast, lifespan 6,000–10,000 h.
  • LED: semiconductor technology. Instant startup, can be used directly with mains voltage (internal driver), lifespan 30,000–50,000 h.

In modern new construction, LED is almost always the better choice. Metal halide lamps remain a sensible option for continued use in existing installations, in locations where the light is on constantly (startup time is not an issue), and in high-ceiling environments where replacement is expensive (longer service life is better).

Can I replace an old metal halide lamp with an LED alternative?

Yes, LED alternatives for metal halide lamps are available. The replacement process:

  • Retrofit LED: same G12 base, but the old ballast can be bypassed or left in place. Check the LED lamp's data sheet for compatibility.
  • Full renovation: replacing the entire luminaire with an LED-compatible one. Handled by an electrician.

The benefits of switching to LED in large facilities are significant: energy consumption can be halved or even reduced to a third, service life is 3–5 times longer (less maintenance work), and instant startup (suitable for various uses). Consult an electrician regarding LED options.

Why does a metal halide lamp turn off and require a cooling period?

In a metal-halide lamp, light is produced by the discharge of ionized metal gas. This requires:

  • Heating during start-up: the gas must warm up to the ionization temperature (1–4 minutes)
  • Cooling after switching off: before a restart is possible (5–10 minutes)

If the lamp is accidentally switched off during operation—e.g., a power failure—wait 5–10 minutes before restarting. Restarting too soon may shorten the lamp's service life or cause it to break.

This characteristic is the main difference compared to an LED—an LED can be switched on instantly in any situation.

Does a metal halide lamp fit all light fixtures?

No. A metal halide lamp requires a special luminaire that includes:

  • A compatible ballast: correctly sized for a G12 metal halide lamp
  • Heat-resistant construction: the lamp gets very hot during use
  • Protective cover: for safety, in case the metal halide bulb breaks
  • Adequate airflow: to prevent overheating

Do not attempt to install a metal halide lamp in a standard halogen luminaire or an E27 spotlight — the bases (G12 vs E27) are not even compatible. Check your luminaire's instruction manual for requirements, or consult an electrician.
