The Thorgeon HPL-N 700W is a high-power mercury lamp with an E40 base, producing 42,000 lumens of natural white 4000K light. It is intended for professional use in large industrial halls, sports field lighting, pole luminaires, and outdoor lighting for industrial areas. It operates in established mercury lamp systems together with an appropriate ballast and ignitor.

E40 base. Requires a ballast and ignitor. Contains mercury.

⚠ Order product

This product is an order product — delivery time is approximately 2 weeks from the order. Please consider this if you need the lamp quickly.

ℹ Aging technology — consider an LED alternative

Mercury lamps are an older lighting technology that is gradually being replaced by LED counterparts. If your system allows for an LED replacement, consider industrial LED luminaires — energy savings are typically 60–70% and the lifespan is up to 5 times longer. This product is still available for the maintenance of existing systems.

Compatibility and installation

Requires a ballast and ignitor

The internal lamp voltage of a mercury lamp is 110–125 V, not the household 230 V. This means that the lamp requires a ballast and ignitor, which convert the mains voltage to the correct internal voltage and ignite the lamp. Check that the luminaire has:

  • An appropriate ballast designed for a 700W mercury lamp
  • A compatible ignitor (starter relay)
  • An E40 lamp holder suitable for a high-power lamp

If needed, compatible control gear can be found in our selection under Electrical Supplies → Control Gear/Ballasts.

Professional high-power lamp

The Thorgeon HPL-N 700W is a professional mercury lamp, used especially in:

  • Industrial halls and large warehouses — high spaces requiring powerful general lighting
  • Sports fields — football, ice hockey, and other large outdoor fields
  • Pole lighting and street lighting — road and street lighting, parking areas
  • Outdoor lighting for industrial areas — yards, loading areas, storage areas
  • Stage sets and general lighting for exhibition halls — large spaces for events

Lifespan and warm-up time

The lifespan of mercury lamps is typically 15,000–24,000 hours and the warm-up time to full power is 3–7 minutes from ignition. The lamp heats up before reaching full light output, so it is not suitable for spaces where immediate powerful light is required (e.g., high-frequency lighting or emergency lighting).

Contains mercury — recycling is important

This lamp contains mercury, which is harmful to the environment. At the end of its lifespan, the lamp must be recycled in accordance with the WEEE directive (Waste from Electrical and Electronic Equipment):

  • Do not place the lamp in general waste
  • Take the end-of-life lamp to the nearest WEEE collection point (e.g., recycling centers, electrical supply stores)
  • Especially for professional use — property management must have a mercury lamp recycling agreement

Note on color rendering — CRI 40–59

The Color Rendering Index (CRI) of this lamp is 40–59, which is low compared to, for example, LED lamps (CRI 80–95) and halogen (CRI 100). In practice, this means that colors do not appear natural under mercury lamp light — greens are accentuated, reds fade. This is typical for mercury lamps and the reason why they are mainly used in outdoor lighting and industrial spaces, not in spaces where color rendering is important.

Installation checklist

  1. Check that the luminaire has an E40 base (not E27)
  2. Check that the ballast and ignitor are designed for a 700W mercury lamp
  3. Check that the overall dimensions of the luminaire (Ø155 × 339 mm) fit the lamp holder
  4. Use protective gloves during installation — do not touch the lamp glass with your fingers
  5. Install with power disconnected — screw the lamp into the E40 holder and ensure it is firmly in place
  6. Turn on the power — wait 3–7 minutes for full power to be reached
  7. At the end of its lifespan, recycle according to the WEEE directive

Usein kysytyt kysymykset

Can I directly replace an old 700W mercury lamp with this one?

Yes, if the old lamp was a 700W mercury lamp with an E40 base. Please check that:

  • The luminaire's ballast is designed for a 700W mercury lamp (not a different wattage or for a different lamp)
  • The ignitor (starter relay) is functional
  • The E40 base and lamp holder are suitable for a high-power lamp
  • The luminaire's space is sufficient for a 155 mm diameter and 339 mm length

If all these points are confirmed, the replacement can be done as a simple lamp change. The installation for larger industrial and outdoor lighting systems is carried out by an electrical contractor.

Is it worth switching from a mercury lamp to an LED light?

In the long run, yes — the LED option is almost always worthwhile:

Energy saving: A 700W mercury lamp can be replaced by an approximately 200–250W LED luminaire, which produces the same light output. Energy saving of about 60–70%.

Lifespan: An LED luminaire lasts 50,000–100,000 hours, a mercury lamp 15,000–24,000 hours. The replacement interval for LED is significantly less frequent.

Color rendering: LED produces CRI 80–95 color rendering, while a mercury lamp only produces 40–59.

However, note that an LED replacement requires either replacing the entire luminaire (remove the ballast, install a new LED driver) or using a retrofit LED lamp that is compatible with the existing ballast. If the system is new or needs upgrading, LED is clearly the better choice.

Why is the color rendering (CRI) of a mercury lamp so low?

Mercury lamps produce light in a gas discharge of mercury vapor, which primarily emits UV radiation and visible light from the blue, green, and yellow regions — but very little red. For this reason, the CRI is typically only 40–59 (for comparison, perfect natural light has a CRI of 100). In practice, green and blue colors are emphasized, but reds, oranges, and skin tones appear unnatural. This is why mercury lamps are mainly used in outdoor lighting and industrial facilities where color rendering is not important.

How do I recycle an end-of-life mercury lamp?

Mercury lamps must not be disposed of with mixed waste — they contain mercury, which is harmful to the environment. Recycling is carried out in accordance with the WEEE directive (Waste from Electrical and Electronic Equipment):

  • Take the end-of-life lamp to the nearest WEEE collection point (Waste from Electrical and Electronic Equipment collection). These can be found at municipal recycling centers, electrical supply stores, and hardware stores.
  • Especially for professional use — facility management and electrical contracting companies often have their own mercury lamp recycling agreement.
  • Do not break the lamp during transport — mercury vapor is harmful to health. Use the original packaging or a sturdy plastic bag.
