Don't forget to turn off the power to the lights before starting work.

Security lights usually come in a box with a mounting bracket and a Halogen light filament.
Try not to handles the light filament with your fingers.

Firstly, work out where your power will come from. As your power source is normally inside a hole will have to be drilled in the wall for the power cable.
If you find the prospect of chasing out channels in walls to access a power point(for example a power socket) then you can fit the cable with a mains plug. If you have a nearby socket to your exterior wall, this is a quick and easy way to get your security light up and running.
The security light itself must not be installed upside down nor sideways.
Don't install the light too low down; about 2 meters from the ground is suitable. Remember this product gets very hot so put it where children are unlikely to touch it.
Decide where you want the light to be and fix the holding bracket there.
The light should not be attached to the bracket at this stage.
Before you put the light fitting up, have a good look at the sensor controls. Then when the light is fixed in position it will be easier for you to adjust the controls bearing in mind that they will appear upside down as you are looking up. Also, the controls are very small.
Do not fix near flammable materials or near to plants.
Use 3 core flex; that is live, neutral and earth.
Unscrew the back of the wiring box.

Work the cable through the access gasket on the side of the wiring box. It may be a tight fit as there is a rubber ring which has to fit round the cable. On some wiring boxes you can take out this ring and force it over the end of the cable; on others it does not come out soyou have to force the cable through. This is to ensure that the light is waterproof.
Inside the wiring box there is a terminal block with four parts. All the wires will be coming out of the same side of the terminal block. There should be six wires on that side.
Your three wires will come in from the opposite side of the terminal block.
Just match the color of your wires to the color on the opposite side.
Brown to brown; green/yellow to green/yellow; and blue to blue. There will probably be another wire in the blue slot(opposite you) but that does not affect where you put your blue wire.
Make sure all the wire are in tightly and screw the back on the wiring box.
Next bolt the light on to the holding bracket.
Undo the at the top of the light and swing down the front surround with the glass in it. Often the halogen filament(in a small cardboard container) is inside so prepare to catch it.
Fit the filament gently in place. Look closely before you do, so you know where to position the ends of the filament.
Screw the front window back on.

Switch on the light to test it.
If it does not come on then it is probably one of four things:
1. The mains supply is not switched on.
2. The halogen filament is not seated correctly.
3. You have a fault in your wiring somewhere.
4. You have not put the light setting completely anticlockwise and the sensor is picking up daylight.
If the light does come on, it should stay lit for only 5 - 10 seconds as the setting is at its lowest.
When you walk in the detection area the light will come on again.
Move the timer control clockwise to increase the time the light stays on.
When you are satisfied with the time delay turn the light adjustment control fully clockwise, which means the light will not come on until completely dark.
Wait until dusk and turn the light adjustment control back anticlockwise until the light comes on.
