What is Paulmann's guarantee policy for bulbs?

What is Paulmann's guarantee policy for bulbs?

We guarantee all Paulmann products for 5 years. This guarantee does not cover bulbs.

Will a bulb with a GU-base fit in a GZ-fitting?

Will a bulb with a GU-base fit in a GZ-fitting?

Yes for "GU in GZ", but no in the case of "GZ in GU". GZ bulbs give off heat to the back, and could cause the lighting fixture to overheat. For this reason, GU sockets are installed in temperature-sensitive lighting fixtures to ensure that GZ bulbs cannot fit into the sockets.

What is the difference between high-voltage and low-voltage halogen bulbs?

What is the difference between high-voltage and low-voltage halogen bulbs?

The service life of high-voltage bulbs is shorter than low-voltage bulbs (for high-voltage 1,000 to 1,500 hours, for low-voltage up to 10,000 hours). Low-voltage bulbs provide almost twice the light yield.

The high-voltage bulbs can be dimmed with leading-edge phase as well as trailing-edge phase dimmers. For low-voltage bulbs, this depends on the transformer. In general, electronic transformers are dimmable with trailing-edge phase dimmers. With the use of a Paulmann Profi transformer (70-150VA) or Mipro transformer, low-voltage bulbs can also be dimmed using any dimmer. A conventional transformer is dimmable with a leading-edge phase dimmer.

With high-voltage systems the installation depths are deeper than with low-voltage systems; as a result, no transformer is required for high-voltage systems.

What does the +C specification on reflector lamps mean?

What does the +C specification on reflector lamps mean?

This symbol stands for "with cover glass".

How many light bulbs can be expected to fail within a particular service life?

How many light bulbs can be expected to fail within a particular service life?

Determining the theoretical rate of failure for an installation: If a large number of bulbs are used in a particular area, it goes to follow that there a certain monthly failure rate has to be expected. The following formula, based on an average service life of 1,000 hours, can be used in order to approximately calculate this failure rate:

Is it possible to dim an LED?

Is it possible to dim an LED?

There are dimmable LED bulbs that are specially labelled as dimmable. LED light bulbs without this designation cannot be dimmed. more

Why do the LEDs in GU10 LED lamps have an "afterglow"?

Why do the LEDs in GU10 LED lamps have an "afterglow"?

LED lamps are dimly lit or have an afterglow:

Cables that lie parallel to the wall create a capacitor. Capacitors have a propensity to conduct AC voltage. The amount of energy conducted depends on the size of the capacitor. This capacitor effect is also used within certain LED lamps in order to reduce the mains voltage.

Capacitors that result from parallel cables in the wall only conduct extremely small quantities of energy that are neither dangerous nor registered by electric meters. The minimal energy consumption of most LED lamps may result in a dim glow. To demonstrate that this really is coming from cable capacities, an incandescent bulb can be mounted in the electric circuit. The glow disappears then.

These minimal quantities of energy are also conducted in the case of incandescent bulbs, but because the resistance of the filament in the bulb is so minimal, the energy is not visible.

 

 

Energy Saving Lamps

Is it possible to dim energy-saving bulbs?

Is it possible to dim energy-saving bulbs?

Paulmann Energy Saving Lamps are not dimable. more

Why doesn't the energy-saving bulb light up at extremely low temperatures?

Why doesn't the energy-saving bulb light up at extremely low temperatures?

The time required for a fluorescent lamp to light up depends on the ambient temperature and the mains voltage. The lower the ambient temperature, the longer the time required for the lamp to light up. The lower the mains voltage, the longer the light-up time.

Energy-saving bulbs are designed for a minimum temperature of -10 °C. At temperatures under -10 °C, the bulb may not function perfectly.

What should I do if a compact fluorescent bulb breaks?

What should I do if a compact fluorescent bulb breaks?

If a bulb in a lighting fixture breaks, first disconnect the lighting fixture from the power supply to prevent electric shock.

  • Ventilate the room and leave it for 10-15 minutes while allowing a strong draft to clear the air.
  • Take care to avoid being cut by the glass shards.
  • Tip: Wear disposable or household gloves.
  • Collect all of the pieces of the bulb, ideally by sweeping.
  • Use a moistened, disposable paper towel and, optionally, adhesive tape to pick up the small pieces and dust.

 

 

Illuminants for Plants

Do the grow lights really affect the growth of plants?

Do the grow lights really affect the growth of plants?

Ausstrahlwinkel

Paulmann grow lights for plants help plants grow by providing the optimal amount of light where the plant is located. Growth results that go beyond those from providing the optimal brightness can only be achieved by using HQ gas-discharge bulbs (mercury gas). This requires a lighting fixture with a special electronic ballast and a bulb that is filled with mercury and gas.
