The term 'Security lighting' is used in relation with preventive measures taken against criminal activity in a property or place. Security lighting is used to increase the sense of safety and as a tool to deter criminal entrance or intruders.
"Installing security lighting fixtures can not only add security to your home, but can often decrease your home owner insurance payments."
Research shows that security lights provide a feeling of security as people feel unsecured in dark and more relieved in light. And the various types of security lighting were introduced to reduce the risk of intrusion.
Security Lighting can also benefit homeowners and invited guests with added functionality, especially in areas where there are no nearby street lights or the house is set back far from the street. Good security lighting can make it easier to navigate driveways and paths in the dark.

Security lights are not only used for domestic purposes, but also in industries, offices, commercial buildings, institutes and virtually any location security is desired. Other than providing a sense of protection they aid in spotting intruders and stopping the entry of unwanted persons.
Security lights should be designed carefully as lighting can obstruct vision by producing glare.
Security lights should either be covered by protective materials such as wire mesh or polycarbonate shields. They should also be mounted high to be out of the reach of trespassers and provide a clear unobstructed field of vision.
Electricity and the circuit are the backbones of lighting. Therefore, other than securing security lights, the entire circuit should be protected from an intruder's access.
There are many different types of security lights available in the market but most can be categorized into three parts: a) HID or High Intensity Discharge, b) Halogen or Incandescent and c) LED or Light Emitting Diode.
High Intensity Discharge generally known as HID, is a technology where a capsule of gas replaces filament of the light bulb. In case of HID lamps, current passes through a metal vapor which produces the light. These types of security lights produce very low light when lit initially; say about 5% only. But after 15-20 seconds they start giving their complete output. The only problem with several types of security lights (High Intensity Discharge) is in case of power loss or it is turned off, the arc tube which produces light takes around 15-30 seconds to cool down. At this point, the HID lamp has to be re-lit to produce light and one has to wait.
A HID lamp comes with a number of advantages with it. A general 18 Watt HID produces light which is roughly the same amount of light produced by a 55 Watt halogen bulb which is around 4 times better results. The color temperature of light produced by this type of security light (HID) comes more close to the color temperature of natural light (sunlight) and at night feels more blue, while the light produced by halogen looks similar to normal indoor lighting. Moreover, the lamp life of a HID is about 10,000 hours which is around 4 times longer than other types of security lights. The color temperature of a HID is approximately 5000K.
This type of security light is used in landscaped gardens. It is also used in cars for brighter and whiter light as it stretches meters ahead of the car and thus ensuring a clear vision for drivers.
Halogen light bulbs consist of filament of carbon which is supported within the lamp envelope and produces light when current is passed through the lamp. This type of security lights (Halogen or Incandescent) requires no time to warm up. They are capable of producing continuous and instantaneous and are generally referred as floodlight.
This type of security light gives a yellowish color and is generally used for aesthetic lighting applications. Halogen or Incandescent lights are generally used around private homes, hospitality, and wherever a more indoor and warmer type of light style is required.
Halogen or Incandescent bulbs generally have a round plate which is mounted to a wall or ceiling. This type of security light can be installed without much mechanism with a thumbscrew. The light produced by halogen bulbs can swivel in any direction and thus locks in place.
While designing a Halogen or Incandescent bulbs which is to be used for as security lamp, one should consider the aspect of light glaring. It should be designed in such a manner that they have glare shield which would help in directing the light in a required direction where it would serve the real purpose rather than spreading the light in all directions.
Halogen or Incandescent are generally used where intimacy and comfort are required. This type of security light is available at a low cost in the market And the CRI of a general halogen bulb is 100 and it produces vibrant and pleasing colors.
Incandescent type of security lights are used for small, medium, and even large scale lighting needs. Halogen and Incandescent bulbs are commonly available from 50 to 150 watts. These bulbs provide high density and warm illumination of light for a compact property. They are used to light the sheds, garages, walkways and driveways.
These days' markets are flooded with numerous kinds of security lights as people have become aware of the benefits of using different types of security light. Now they understand that even criminals choose a dark place to move around or to cultivate any criminal activity than a well lit place. This has not just resulted in better sales of various types of security lights but has also reduced the number of criminal activities.
Motion-detectors, light sensors, and timer lighting are examples of this type of outdoor lighting. Other types of security lighting, such as porch lighting or outdoor garage lighting are easier toinstall but can be less effective.
Installing security lighting fixtures can not only add security to your home, but can often decrease your home owner insurance payments. Check out your insurance policy to see what kind of provisions it makes for home security lighting.
The following details how to replace your current outdoor lights with security lights:
If you can reach your fixture without using a ladder, it's probably too low. It would be as easy for a burglar to reach up and simply unscrew the bulbs. In this case it would be recommended that you have a new outlet box and light assembly installed at a different location that is out of reach. security-motion-sensor-lighting.jpg
Motion sensing security light fixtures come in many configurations with options of multiple bulbs, sizes, shapes and styles, from utilitarian floodlights with adjustable motion-sensing elements mounted on an arm to decorative coach lights with fixed motion-sensing elements. First decide if you want an adjustable or fixed motion sensing element, then choose the style of light fixture that best suits your taste.
Do It Yourself or Possibly Hire an Electrician?
When exterior lights were already installed in your home, installing a new security light may be a quick and simple project. If no exterior lights are installed yet, you need to take in consideration that electrical wire may need to be run to every new location for the motion lights and you might need an expert electrician to help with this.
The steps needed:
Remove the existing light Fixture.
As a first step and for safety, turn off the electric power at the fuse or circuit panel. There may be a few pairs of wires in the electrical wall box (Jbox). Some of the wires may be connected to different circuits than the fixture you are working on. To be on the safe side, check if the power is off by using a voltage meter.
Locate and remove the cover and the light bulb from the fixture.
Release the light fixture from the base by unscrewing the screws that hold the fixture to the wall box and expose the wires and junction box.
Uncover the wires to expose them by removing any wire nut or electrical tape. White is neutral, Black is hot, and green is ground. After you make sure that the wires do not come in contact with each other you may re-energize them by activating the power and test to insure that power is present in the wires. After this is done you may turn the power back off.
Wrap the exposed wires with electrical tape, leaving the last 1.5" bare.
Installing a new light fixture
Place the new light fixture's sealer gasket over the outlet box.
On the new light unit, strip about 1.5" of insulation from the ends of each of the electrical wires and then connect the wires.
Twist the ends of each wire pair together.
Reactivate the power. Use the voltage tester to make sure power is flowing to and from the fixture.
Shut off the power again and with the help of wire nuts, attach the wires of the new fixture to the matching wires in the electrical box. Cover the wires and wire nuts with tape to seal your splice.
You should also have an existing grounding wire (normally copper or green color) already connected to the electrical box. Make sure to attach it to the grounding screw on the light and the junction box ground screw.
Position the new base plate and screw the new bolts through it so it attaches to the mounting strap.
Carefully tuck the wires back into the electrical box.
Place the light fixture base plate so it aligns with the screw holes in the junction box and with the provided screws; mount the light fixture's base plate to the box. It's important that all the wires are completely contained and protected by the light fixture housing.
Screw in the light bulb then replace the bulb cover if included. Many bulbs are sensitive to oils and other material that may get on them during installation. To protect against damaging the bulb, wear lightweight gloves to install the fixture's bulb.
Seal the housing.
Turn on the power.
Adjustment of the light motion sensor
Most motion sensors also have a sensitivity adjustment. You will want to adjust this so that small animals or wind blowing through trees, do not inadvertently trigger your lights. Most sensors allow to adjust the distance at which it detects motion, as well as the sensitivity which is the level of motion that triggers the light, and how long the light stays on once tripped. Test the light at night with the switch first, and then, leave the switch in the ON position. Don't move, and watch for the light to turn off in a few minutes. It should reactivate when you move. Use the manufacturer's instructions to adjust the motion sensors as necessary.
