Parts of the halogen lamp
o switching it on and off works just like with a regular lamp
o the essential parts are an entry cable, the work through which the electrical current flows, a transformer where the change in voltage takes place. Generally it goes in at 220/230 volts and comes out at 12. The third part is the supplementary cable that goes to the halogen mechanism itself.
o Later you can install whatever kind of low-voltage light bulb you want, depending on the lighting needs of the room.
o There are also normal-voltage halogen reflectors that do not need a transformer.
o A halogen lamp allows you to adjust the amount of light emitted. It is a white light with a great capacity for brightening a room.

Where to place it
o Normally, halogen lamps are embedded in the ceiling, if it is hollow and made of dry wall, plaster or something similar. But they can also be set in the wall.
o In this system the lamp housing and the transformer are embedded in the ceiling (or wall), while the diffuser is flush with the ceiling or sticks out just a bit.
o These lamps are ideal for rooms with a low ceiling.

Making the grooves
o Trace lines on the wall and ceiling to run the new cable to the place where you want to place the lamp.
o Use a pickaxe and hammer to make a small groove, just wide enough to hold the tube that will contain the cables.
o In the spot where you are going to embed the transformer and housing, you have to make a hole large enough to work comfortably and introduce these parts. Later they will not be visible.
o Cover the tubes and grooves with plaster until the surface is flush with the ceiling or wall.
o When it is dry, if necessary sand down before painting.

How to install the lamp
o Once you have chosen and prepared the spot, connect the current-carrying cables to the terminals of the transformer.
o Attach the transformer to wooden plank or directly onto the surface of the plaster.
o Make the connections of the cables that run from the transformer to the lamp housing.
o Follow the manufacturer's instructions and use whatever decorative cover is provided.

A tip
As with all electrical work, turn off the main electricity switch in your house. But this warning is only applicable when you are connecting cables.
