Questions & answers about our Paulmann products

The URail rails in the lengths 0.10 m, 0.50 m, 1.00 m and 2.00 m must only be shortened by a qualified electrician, as unprofessional work could result in an electrocution risk during later operation.

NEW: URail cutting service: We will shorten your URail light rails for you in our in-house Paulmann workshop. Simply select the length you want during the order process.

Some LED lamps are specifically labelled as dimmable. LED lamps without this labelling cannot be dimmed.

A minimum installation height for each recessed luminaire type is indicated on the packaging of the set. An insufficient suspension of the ceiling will lead to the following problem: With its height and width, the transformer may fit through the mounting hole. Due to its length, however, the transformer will get stuck when inserted into the hole. The transformer must be installed elsewhere, but make sure to keep it accessible. Our range includes special round transformers for easy installation in suspended ceilings.

Disc 70: Diameter = 53 mm H = 22 mm

Disc 105: Diameter = 71 mm H = 22 mm

Dimmers work like fast electronic switches. That means, a dimmer switches off the lamp/luminaire for very short periods of time. These On/Off processes cause abrupt changes in the magnetic field of conventional transformers. These changes in the magnetic field causes the transformer windings to vibrate, which can be amplified particularly by wood ceilings.

A slight loosening of the fixing screws can help reduce that effect. Alternatively, you could place a rubber profile between the transformer and the ceiling. That will also help reduce vibration.

Any installation must have a dimmer to match the lamps and/or luminaires. All Paulmann transformers (230/12 V AC) are dimmable.

• For LED lamps, you will need either a leading-edge dimmer or a trailing edge dimmer.
• Halogen 12 V lamps with electronic transformer usually operate with a trailing-edge dimmer, while halogen 12 V lamps with a conventional transformer usually operate with a leading-edge dimmer.
• 230 V halogen lamps can be dimmed with any dimmer.

The three letters "R", "L", "C" or a combination thereof denote dimmers and electronic transformers. You have made the right combination choice for transformer, dimmer and lamp if their relevant letters match.

If you dim your halogen lamps frequently, you should make sure to switch to full brightness from time to time to re-stimulate the halogen cycle in the lamps and ensure a maximum service life.

Mains voltage halogen and low-voltage lamps, as well as incandescent light bulbs can be easily dimmed.

LED lamps and LED luminaires can be dimmed if they are specifically designed for it and labelled accordingly. There are also some dimming technologies that are directly integrated in the lamps – these include Zigbee, 3-Step-Dimm and Easydimm.

The dimming feature has not been widely adopted for energy-saving lamps.

Residual or afterglow of LED lamps:

Parallel cables inside your walls act like a capacitor. Capacitors conduct AC voltage. The amount of transmitted energy depends on the size of the capacitor. The same capacitor effect is used in some types of LED lamps to reduce mains voltage.

However, capacitors created as a result of parallel cables within walls only transmit minimal amounts of energy, which are neither dangerous nor registered by electric meters. The minimal energy consumption of some LED lamps may cause a dim glow. Simply mount a regular incandescent lamp in the electric circuit to see, whether the glow is actually the result of cable capacity. The glow will disappear where that is the case.

These minimal amounts of energy are also transmitted in regular lamps, but will not be visible due to the low coil resistance of the lamp.

Some LED lamps are specifically labelled as dimmable. LED lamps without this labelling cannot be dimmed.

LED technology now offers new and advanced dimming options that are pre-integrated into the lamps, e.g. 3-Step-Dimm and Easydimm. Additionally, there are LED lamps that can be controlled via remote control, smartphone or voice command.

YourLED Strips (12 V DC) are coated LED strips for decorative lighting that can also be used in wet rooms. The uncoated YourLED Eco Strips (12 V DC) are perfect for extended routing. YourLED Strips are coated LED strips for decorative lighting that can also be used in wet rooms. The uncoated YourLED Eco Strips (12 V DC) are perfect for extended routing.

MaxLED Strips (24 V DC) are the perfect choice for area and room lighting. They too come with or without coating. The output of one metre of MaxLED 500 is similar to a 40 W light bulb. One metre of MaxLED 1000 is as bright as a 75 W light bulb.

You have two options for controlling the LED strips via app.

Depending of the type of strip you have chosen, you will need a BLE Controller and the Paulmann Home app for control via Bluetooth. Have a look at our advice section for more information about lighting control via Bluetooth and the app download link.

You will need a Zigbee controller and a gateway with the right app if you want to integrate the strips with other systems and devices in your home into one networked system. Here you will find out more about Zigbee light and Smart Home control, the gateway and the app.
