LED Lighting From A to Z

Replacement original lighting with LED lighting

  • Dimming phase cut-off
  • Dimmers with phase cut have the letters RC on the dimmer. These dimmers are suitable for incandescent lamps, 230 volt halogen, 12 volt halogen, dimmable LED lamps and dimmable energy saving lamps.
  • By dimming lighting with the phase cut-off method you can save energy. With a dimming range of 100% you can completely dim the lamp until it is off.
  • Almost all dimmable lamps are dimmed based on the cut-off principle. When you choose phase cut, you choose the most energy efficient principle.
  • Dimming phase cutting
  • Dimmers with phase cutting have the letters RL on the dimmer. These dimmers are suitable for incandescent lamps, 230 volt halogen and some of these dimmers can also dim LEDs. This must be specifically mentioned on the dimmer.
  • A dimmer with phase cut has a dimming range of 40%. A lot less! With this way of dimming, it will never be possible to dim the light source completely.

Question and Answer

How do we disassemble a chandelier on site?

There are different ways to take down a chandelier. Many chandeliers are very heavy and cannot be brought down without an aid.

Canal lift

Up to 8 meters height (top side chandelier) the whole chandelier can be brought down with a hoist lift. Chandeliers up to 500 kilograms can be brought safely to the floor.

Up to a height of 12 meters (top of the chandelier) the chandelier can be brought down via a ladder or scaffold provided the arms are removable and lowered by 25 kilograms each.

How do we pack a chandelier for transport?

The separate parts of the chandeliers are labelled one by one. After labelling, each component is carefully wrapped in foil. For each chandelier there are wooden transport boxes where the same parts are neatly put together.

How do we check threads?

By means of a magnifying glass the thread can be checked for damage. In case of doubt, another tensile test will be done with five times the total weight of the part. We do this to make sure that the thread is strong enough when the chandelier is reassembled.

How do we check a weld?

By means of a magnifying glass the weld can be checked for damage. In case of doubt, another tensile test will be done with the total weight of the product x 5. This to make sure that the thread is strong enough.

How do we polish a chandelier?

Chandelier parts are polished by means of a polishing machine with polishing discs. The polishing discs are provided with polishing paste in different gradations. By moving the part of the chandelier along the brush, it is lightly sanded and the shiny surface of brass reappears.

How do we paint a chandelier?

By means of a two-component lacquer/varnish we lacquer the parts of the chandeliers. After complete curing (24 to 48 hours), these are sealed off from oxygen and thus no oxidation can occur. In this way the dark and duller are postponed. Oxygen is the culprit of the blackening of the brass.

How do we assemble a chandelier?

By means of numbers/letters or labels we can put the chandelier back together again. The basic parts are secured on a steel rod. The arms are secured by plug-in pins.

How do we electrify a chandelier?

There are two ways to electrify chandeliers. 17th century chandeliers have massive arms and therefore no electricity cables can be pulled through them. We use gold wire and small gold ty-raps to attach the cables to the chandelier arms. From a height of 2.5 to 3 meters this wiring is almost invisible with the lighting on.

The 19th century chandeliers have hollow arms through which electricity cables can be drawn. In this way the cables are invisible.

How do we make a chandelier adjustable in height?

By means of an electric winch we can adjust chandeliers up to 15 meters in height. This makes it possible to lower the chandeliers up to 1 meter above the ground for easy cleaning. If for an event the chandelier has to be raised then this can be adjusted with one push on the button.

How do we mount a chandelier?

After maintenance, the chandelier will be transported in its entirety to location, the chandelier will usually be transported in a wooden transport box. The transport box is rolled to the right place. From there the chandelier will be hung on the hook by means of a duct lift. With accompaniment of a scaffolding or a high staircase it is possible to guide the chandelier up and connect it.

How do we make chandeliers maintenance-free for 15-20 years?

By means of a 2-component lacquer we seal the brass from the oxygen that causes oxidation. See question lacquers.

  • If electric chandelier
  • Re-assembly of cabling
  • Mounting LED luminaires
How can you tell a chandelier needs maintenance?

What can you tell that a chandelier needs maintenance?

  • Yellow colour is very dull and/or brass does not shine anymore
  • Black spots under the lacquer, brass in far state of oxidation
  • Leaves of lacquer
  • Different colors of lacquer, stains

We can make all the dull chandeliers shine again and restore them to new condition.

Recommended by the Cultural Heritage Inspectorate

After restoration, the chandeliers are indistinguishable from new ones. The Cultural Heritage Inspectorate values the craftsmanship of Brink & van Keulen so highly that they recommend their treatment for monumental crowns instead of regular polishing!
