Low Voltage Recessed Lighting – Spotlights, transformers, and connecting wires are in direct contact with the vapor barrier. The temperature rise generated by these three components in operation is such that it causes the combustion of kraft paper which is an easily combustible material. The “Very low voltage” spots to recess in a false ceiling are currently raging. And for good reason, they are rather easy to install and their halogen bulbs are economical.
Attention, first of all, starts by cutting the circuit breaker. Draw on the ceiling the diameter of the area to be cut (which must correspond to the inside diameter of the low voltage recessed lighting, that is to say, the part that will be invisible) with a hole saw or a handsaw at the window. If the manufacturer has provided you with a template, you will tape it to the ceiling and trace its outline with a simple pencil. If the circumference of the drilled hole is too rough or uneven, sand with fine-grained sandpaper.
TBT low voltage recessed lighting work with a transformer. Connect the existing circuit to the input of the transformer (220 V), then connect the wires of the socket to its output 12 V. Insert the transformer in the hole, and place it about 20 cm from it. Attention, it is possible that no circuit is present in your false ceiling. In this case, you will need to pull wires and bring them there.
