A low voltage system that uses conductive voltage cables to offer endless variations of high-tech lighting arrangements is called cable lighting. The cables that are hung with surrounding, accent or decorative luminaires and run parallel under the ceiling. This makes your cable lighting the best choice when you cannot access an electrical power source from the ceiling due to vaulted ceilings or cathedral ceilings or exposed ducts. The cables can be mounted ceiling to wall, ceiling to ceiling or wall to wall as they can change direction.
In different cable lighting systems, the amount of cables required by different methods is determined. Usually the length of the run is multiplied by two (this is done for each cable) and a little extra is added for adjustment and turns.
For cable lighting, the cables must be hung up; what type of installation, say wall to wall, ceiling to ceiling or ceiling to wall will determine for you what type and how many roof supports you need. You may need rigid or flexible support and this depends on your design. Extra support may be required for runs that are more than 20 feet or if you use heavier luminaires. If the drive is to overcome the large height difference, it should be taken into account when choosing your suspensions. The angles of your cable run can be changed by reusing the routers.
Source of power
Since cable systems have low voltage, a step-down transformer is required to reduce the input voltage to 24 or 12 volts. Transformer remotely mounted or surface mounted. The power is delivered from the transformer to the cables through the power supplies. To determine the desired wattage from the transformer, sum up the wattage of the lamp to be connected in the system. Another transformer may be required if the sum of the watts consumed is over 300 watts at 12 volts or 600 watts at 24 volts.
In cable lighting systems, you should take into account the amount of watts you are going to work with and what you are going to light. The cable system is an excellent solution for ambient, direct or accent lighting. If ceilings cannot accommodate recessed lighting due to beams, track lighting can be used. This allows you to place luminaires close to the ceiling and keep the lines of sight clear.
