Lighting System
Lighting system : means the combination of components required to provide a certain light level. Sample 1.
Lighting system means all exterior manmade lighting sources, associated infrastructure and controls on a site.
Lighting system : usually required for various buildings such as residential, commercial and industrial buildings
and for roads and public spaces streets,

 Lighting Circuits: Lighting circuits are basically radial circuits. There are two distinct types of lighting, circuit the loop-in circuit and the older
junction box circuit. Most houses combine aspects of both types of circuits. The loop-in circuit has a cable, running from
light to light terminating at the last light as in the conventional radial circuits and then single cable run from the lights to
the light switches.
The other type of lighting circuit has a junction box for each light. The cable runs from the consumer unit to the first
junction box and then onto the next terminating at the last junction box. Then another cable is run from each junction box
to its light and another wire from the junction box to that light switch.The cable used for a lighting circuit is 1mm2 or
1.5mm2 for long runs.
A 5amp fuse or 6amp MCB is used on the consumer unit for a lighting circuit. The maximum load for a lighting circuit is
1200 watts, which amounts to 12 x 100 watt lights. If more lights are needed then another lighting circuit should be used.
It is usual to have 2 lighting circuits in a house one upstairs and the other downstairs.

How Many Lights Can Be Installed on One Circuit Breaker?
 In order to figure out how many lights can go on one circuit breaker, you need to know what follows.
 Electrical Panel
Before any circuit breakers can be installed, you must have an electrical panel. This box has the main electrical line
coming in from outside. This line is then branched off to different circuit breakers.
 Circuit Breaker
There are many different types of circuit breakers. For a residence, there is one main circuit breaker that branches off into smaller amp
(amperage) individual circuits. All the individual circuit breakers combined cannot exceed the total main amp. Each circuit breaker is
designed to trip (shut off) when there is an excessive amount of power going through it.
 Amperage
Amperage, or current, is the amount of electrical energy flowing through any light fixture at any given time. The
amount of amps will be clearly identified on the individual fixture.
 Wattage
Watts are a measure of the use of electrical power. One watt is equal to one volt multiplied by one amp.
 Electrical Wire
Electrical wire carries electricity to the outlets or appliances from the circuit breaker. It is made of a metal that easily conducts
electricity, usually copper, in an insulator. There are different wires made to allow certain loads.
 Conclusion
To figure out "How Many Lights Can Be Installed on One Circuit Breaker," you have to know the following.
50 watt light equals less than 1/2 amp current flow at 120 volts.
You can put up to 30 lights (based on 50 watt light) on a 15 amp breaker.
You can put up to 40 lights (based on 50 watt light) on a 20 amp breaker.

TECHNOLOGY OF LIGHT
Over the years, the technology of light has changed
drastically as science has evolved, yielding new
sources, materials and innovations for lighting. Since
humble beginnings when an open flame served as
the primary source of light, technologies have
advanced to the age of the LED.
Advancements in lighting technology are not limited
to the light source, but include all luminaire
components – today we consider not only the light
source itself, but also a luminaire’s materials,
aesthetics and efficiency. Zumtobel takes this a step
further as we consider the impacts of lighting on
people. Innovations such as our Luminance Reducing
Optic (LRO), which reduces glare and enhances visual
comfort in offices, or our True Gamut Rendering
(TGR) technology that provides authentic color
representation at retail,

One-Way Switching Circuit
Figure 01 shows how a lamp is controlled by a simple one-way switch, providing on
/ off control of the lamp. The phase conductor is connected to the one-way switch,
terminal C, through a suitably rated fuse or MCB, 6-10A. The neutral is connected
directly to the lamp.
When the switch is closed the phase conductor is switched through to the lamp
from terminal L1 and the 230 V supply is placed across the terminals of the lamp
and so the lamp is illuminated.
When the switch is opened the phase conductor is interrupted and the lamp is
extinguished. This occurs when the switch is in the “up” position.
Figure 01 Figure 02
If more than one lamp is required, the extra
lamp or lamps should be connected in parallel
as shown in Figure 02.

One Gang Two-Way Switching Circuit
Figure 03 shows how a lamp can be controlled from two locations providing on / off control from either
location. This circuit is used to control lamps in such places as stairways, corridors and rooms with two
doorways.
The two-way switch has two outputs, sometimes labelled L1 and L2. The third terminal is referred to as
the “Common” terminal and is marked “C” in some cases. This terminal is “common” to L1 & L2. In the
“up” position the common is connected to L2 as shown, and therefore the lamp is “off”. If either switch
is changed to the L1 position the lamp will be “on”. If both switches are changed to the L1 position the
lamp will again be “off”. If the “strappers” are crossed over at either switch, the lamp will be “on” when
both switches are in the “up” position. It is simply good practice to ensure that this does not occur. This
means that it is possible to place all switches in the “up” position and be assured that all lamps are “off”.
It also ensures safety when replacing faulty lamps or flex drops.
Figure 03

We have our two way switches at either end and then an intermediate switch in the middle. We take our live feed and connect
it into the common of switch 1. We then run a brown cable from L1 of switch 1 over to L4 of switch 2. We then run a brown
cable from L2 of switch two, over to L2 of switch three.
We then run a blue wire from L2 of switch 1 over to L3 of switch 2, we place a brown sleeve at each end of the wire to warn
that it is intermittently live. We run another blue wire from L1 of switch 2 over to L1 of switch 3. And then we run a final blue
wire from the common of switch 3 up to the light.
