Lighting for Outdoor Security and LED Floodlights

While doing massive security upgrades like installing a complete alarm system or electric fence are not affordable – installing outdoor lighting is. Whether you install simple LED floodlights or more complex Solar LED lights with motion sensing capabilities – it will significantly improve the safety and security of your home. I will even go so far as to say that it is mandatory.

Throughout this website I have constantly emphasised the importance of outdoor security lighting to improve the security of your home. If you’re looking to buy an LED floodlight with PIR or without, this article will provide you with the relevant information.

DIY light installations are pretty straight forward. You can purchase light online and have them delivered to your home. This will save you loads of time and effort and you can easily and quickly compare the available options to choose the right wattage or lumens that you need.

Why you need to install lighting for outdoor security

Most hijackings and robberies happen in our driveways – especially if the driveway is dark or concealed by bushes and trees. This is simply because criminals always look for easy targets where the risk of being spotted and disturbed are minimal. Better lighting will help you deter burglars, robbers and help you avoid a home invasion.

Having a dark driveway and garden also increases the chances of having your home burglarised during the night and early hours of the morning since, once again, criminals love to do their dirty work in the shadows.

Top 10 reasons to install outdoor floodlights:
  1. For practical reasons – no one wants to be having a braai with a torch in hand or fumble around in the dark to find their keys.
  2. Security – as mentioned criminals tend to avoid well lit areas. It will make it easier for you to spot criminals before you enter your driveway as well as help you spot them from inside your home.
  3. Safety – lighting up your swimming pool area, Jacuzzis and children’s play area can help you keep an eye on your little ones while they play outside
  4. Flood lights will help your security company patrollers spot intruders – especially while you’re away on holiday.
  5. A LED floodlight with a motion senor will help detect intruders and alert you to strange activity in the vicinity of your home.
  6. LED floodlights consume less energy than halogen, incandescent or metal halide lights.
  7. LED floodlights offer more lumens per watt – so your get more light with less energy consumption.
  8. LED floodlights make it harder for criminals on the prowl to see inside your home at night. An important security tip is to always important to draw your curtains to prevent criminals from finding out how many people are home and where everyone is.
  9. LED floodlights are relatively inexpensive depending on the type you require and are also very durable and can last for many years. As with anything that is exposed to the elements – it will corrode over time. Most floodlights are waterproof and are either
  10. You can easily install an LED floodlight yourself so you don’t need to get someone in to do it for you.

What are lumens?

When purchasing an LED floodlight or any other type of light you will come across the word “lumens” in the technical specifications. Lumens refer to the amount of light that can be seen with the human eye from a single light source.

The higher the number of lumens the more powerful and bright the light will be. A standard 40W halogen light bulb offers around 450 lumens while a 60w light bulb offers between 800 and 850 lumens. A 100W LED floodlight offers about 8500 lumens while a typical 50W LED floodlight offers about 4500 lumens.

LED lights are a good choice for outdoor applications because they provide more light with less energy since they do not lose energy by creating heat but rather – more light! While most people know that the higher the wattage of a halogen bulb the brighter it will be, with the increasing popularity of LED’s wattage can actually be quite misleading and you may want to refer to the lumens.

You can roughly calculate how many lumens an LED light has since 1 watt will typically offer 90 lumens.

How many lumens do you need?

The number of lumens or the wattage that you will require from an LED floodlight will depend on where you’re placing it and how much light is required. You should consider:

  • Other light sources – if there are street lights close by, other floodlights or bulbs or lights from surrounding buildings.
  • The area you wish to light – you need to consider that the beam angle of the floodlight is 120o and the lower the wattage or the lower the lumens – the smaller the space will be light up.
  • The presence of trees and shrubbery – trees and bushes make it more difficult for people to see what is going on in your driveway and will also reduce light coming in from nearby sources. See the article entitled garden security for more tips on improving your outdoor security.
  • Although you want to light up your home if you do not opt for a floodlight with PIR sensor and you rely on a timer – you do not want to have “too much light” not only will this consume more energy but it may help criminal easily see what is going on in your driveway and garden as well as possible highlight valuables, entrances, doors, windows and so on.

Types of floodlights

10w led floodlightThe types of floodlights that can be found are halogen floodlights, metal halide floodlights and LED floodlights. In recent years, partly due to the electricity crisis in South Africa and practical considerations, LED floodlights have become the most popular option for homeowners. The “colour” of the light is usually described as either cool white or warm white. LED floodlight housing is made from aluminium and die cast aluminium.

Where can flood lights be used?

LED floodlights can be used just about anywhere including indoors. Not only can they light up your driveway, parking, patio, lapa and garden but they can also be used to light up trees and give a lovely aesthetically pleasing appearance to your garden at night. Although we are primarily concerned with safety and security and preventing your home from being targeted by criminals – additional practical reasons to have good lighting is always considered.

LED Floodlight Wattage

You can get a 10W, 20W, 30W, 50W, 60W, 70W, 80W, 100W, 150W and 200W LED floodlight. If you’re looking to light up different sections of your garden and driveway – since a single light will not do the job – you may want to adjust the wattage based on the size of the space you need to light up. A 10W LED floodlight will suffice on top of an entrance or to light up a dark corner concealed by bushes or trees.

LED floodlights with PIR sensor

PIR stands for passive infrared and is simply a sensor that will detect infrared radiation emanating from objects and trigger the switch to turn your light on. A PIR sensor is “passive” because it does not consume energy to detect the infrared radiation.

I recommend the LED floodlights with PIR because they add an extra layer of security since they can help detect intruders in your driveway and garage as well as save on energy since the light will only be on when it’s needed.

Advice on LED floodlight options
  1. 10W LED Floodlights

A 10W, 12V floodlight offers about 800 lumens and 50,000 hours of operation. This is not ideal for driveways, in my opinion, but, they are great to install above back doors, storerooms, sheds and other outbuildings.  Many 10W LED floodlights come with a motion sensor that typically has a range of between 1 and 8m and are quite inexpensive.

  1. 20W LED floodlights

A 20W LED floodlight typically offers between 1600 and 1800 lumens and is one of the more common options for South African homes. This light will not be so bright that it cause serious glare nor so weak that it can is inefficient.

  1. 50W LED floodlights

A 50W LED floodlight can be used to light up your back yard, garden or driveway. This offers about 4000 to 4500 lumens with a sensing range of about 10m. Using a powerful LED floodlight may seem like a good idea at first but it can cause serious glare and it is usually best to use 2 weaker lights to reduce glare.

For instance instead of using a single 50W LED floodlight in between a double garage to light up the space you can use 2 20W LED floodlights above each garage. Alternatively you could use a compatible dimmer, however, be aware of potential buzzing that may be caused by dimmers.

  1. Solar LED PIR security light

solar powered led lightSolar powered LED lights are easy to install yourself and durable and are the ultimate in energy consumption. Some solar powered LED floodlights offer only about 630 lumens and are 7W lights however, these are ideal if you’re looking for a long term energy efficient security upgrade. The detection area for the Solar LED PIR security light ranges from 3 to 5 meters. Not ideal for driveways requiring lots of light but are fantastic since they will still work during power outages and offer an extra security barrier.

Where to buy LED floodlights

You can buy LED floodlights at any Builders Warehouse or lighting outlet as well as online by visiting Eco Depot, one of my favourite home improvement and DIY online stores. They offer an impressive range of outdoor lighting products at great prices.

Do you have any questions or comments? How long has your LED floodlight lasted? What do you think about the fact that the import of incandescent lights was banned in South Africa in June of 2011?

  2. but mara you want the place to be light up the toti will come to your house, me im using the beams and adt by my house, no light

  3. Looking for flood lights to light outside of warehouse, I find the LED lights don’t last as long as have tried a few different brands, have installed solar in 2 sections but not happy with light, what do you suggest ?

    1. Hi Mario, you’re right since the no-name brands don’t last and are susceptible to corrosion, excessive weather damage, and malfunctioning. It’s hard to say what you should use without seeing the layout and size of your warehouse perimeter but, below are a few suggestions.

      Ellies and EUROLUX are good options across the board: EcoDepot outdoor lights

      You’re probably not happy with the light from the two sections you installed solar lights at because they’re not of the right Wattage or cannot fully recharge due to placement. I suggest a the Ellies 50W (or more) LED solar lights for warehouses and other commercial spaces: EcoDepot 50W solar
