The 125-watt HPL mercury lamp is the most common E27-base mercury lamp in old yard, street, and pole luminaires, as well as in halls and warehouses. It produces 6200 lumens of neutral white 4200 Kelvin light and works in a luminaire equipped with a 125-watt mercury lamp ballast. The average rated operating life is 10,000 hours.

Compatibility and installation

An HPL lamp always requires a ballast rated for the same power, in this case, a 125-watt mercury lamp. A separate igniter is not required. Never connect an HPL lamp directly to mains voltage without a ballast – the lamp will fail immediately.

A similarly sized HWL compact fluorescent lamp looks almost identical, but it works without a ballast. Therefore, always check the markings on the old lamp. The lamp reaches full brightness in a few minutes and will only restart after it has cooled down. The lamp contains mercury: take the used lamp intact to an electrical and electronic waste collection point.

  1. Check the markings on the old lamp: HPL, HQL or HSL and 125 W.
  2. Ensure that the luminaire's ballast is designed for a 125-watt mercury lamp.
  3. Turn off the power and allow the old lamp to cool down completely.
  4. Screw the lamp securely into the E27 socket and wait a few minutes for it to reach full brightness.

Replacing the ballast and making electrical connections should be done by a qualified electrician. Also see Patron SON-E 110 W, Patron HPL 80 W and LED lamps replacing discharge lamps.

Usein kysytyt kysymykset

What is the difference between the HPL 125 W and HWL 160 W lamp?

The bulbs are the same size and look almost identical, but they work differently. An HPL mercury vapour bulb always requires a ballast. An HWL halogen bulb has an internal filament, so it can be connected directly to the mains without a ballast.

Choosing the wrong bulb is costly: an HPL bulb without a ballast will fail immediately. Check the marking on the old bulb. If it says HWL or ML, choose an HWL halogen bulb.

Can a 125 W HPL lamp be replaced with a sodium lamp?

Partially. There are replacement sodium lamps for mercury-vapor lamps on the market, such as the Patron SON-E 110 W, which are designed to work with a mercury-vapor lamp socket without a separate igniter. They produce significantly more light, but the color is yellowish.

Before replacing it, make sure that the replacement lamp is specifically designed for a 125 W mercury-vapor lamp socket. A standard sodium lamp requires its own socket and igniter.

How long does a 125 W HPL lamp last?

The average rated life of the lamp is 10,000 hours. For an outdoor light that is on for about 12 hours a day, that means a little over two years.

The light output gradually diminishes even before the lamp burns out, so the lighting may be dim even while the lamp is still on. In locations with multiple lights, it is recommended to replace the lamps all at once.

Why does the lamp turn on slowly and not immediately again?

This is normal for a mercury-vapor lamp. After ignition, the lamp initially emits a dim, bluish light, and full brightness is reached in a few minutes as the mercury vaporizes.

A hot lamp will not reignite immediately, for example after a power outage, but must first cool down. Therefore, HPL is not suitable for applications where light must return instantly.
