The time of year for exterior lighting is here

Traditionally, most outdoor floodlights have used halogen bulbs, which use 20-30% less energy than older incandescent bulbs, but which come nowhere near LED bulbs for their energy-saving potential. The biggest advantage of LED bulbs in this case is their superior lifespan. Where a halogen bulb might last around 2,000 hours, LED floodlights can last 30,000 hours or more.

In addition to the cost saving that this long lifespan provides, it means that you won’t have to go through the hassle of replacing your floodlight (or its bulb) nearly as often. This alone makes for a good reason to upgrade to LED floodlights. A recent project has been upgrading exterior lighting to an LED lighting solution, and this has meant that the project paid back on its investment within two and a half years just from the energy saved. The products then have another four years of expected service, which means even more energy saving compared to the previous more conventional lighting method. LED really is a no brainer.

There are a few features and technical specifications to look out for when shopping for exterior lighting.

IP rating

Electrical, battery and solar-powered outdoor lights have an IP (Ingress Protection) rating. This refers to how well they’re protected from intrusion of water and dirt.

The first digit of an IP rating refers to intrusion protection – whether you’re protected from its moving parts, as well how protected the equipment is from foreign bodies. So, for example 0: means ‘no special protection’, while up to 6 is ‘totally dust-tight’. The second digit of an IP rating refers to protection against moisture: 0 represents no protection, while up to 8 means protection against prolonged effects of immersion under pressure.

So, for example, a light with an IP rating of 68 will be very protected from both intrusion and moisture, and would therefore be ideal for an exterior location near moisture.

A number replaced by an X indicates that the enclosure is not rated for that specification. Therefore, a light with a rating of X4 hasn’t been rated for intrusion, but offers protection from water spray in any direction.

Location is everything

Before you even start looking for the right outdoor floodlight, determine where you’re going to install it. Most importantly, what area does the light need to cover? The height and angle at which the light is installed could make a big difference as to how well it lights your chosen space.

Windows, doors, drainpipes and gutters may all be obstacles to finding the right placement, so it’s important to think about this early. When you have decided on the right spot, try and get an idea of the size of light that will fit in the space. It would be no good buying a high-powered floodlight, only to find that it’s too big to fit in the position you have chosen for it.

How do you want your outdoor light to activate?

As lighting technology progresses, floodlights are becoming more sophisticated in how they are activated. In addition to the standard on/off switch that you can use to manually activate your light, you can also find floodlights with motion sensors, which will illuminate when someone (or something) passes in range of its sensor. Alternatively, ‘Dusk till Dawn’ floodlights automatically switch on when the ambient light falls to a certain level, and then switch off again in the morning when the sun comes up.

Get the right brightness

Floodlights come in a broad range of brightness outputs, perhaps more than any other type of light. You can find floodlights that output anything between 700-20,000+ lumens.

Which one you choose primarily depends on how big a space you need to illuminate. An outdoor floodlight with only a relatively low lumens output (700-1500lm) will suffice for patios and driveways, while commercial spaces like car parks and small fields will obviously need high-powered floodlights that output many times that. There is no hard and fast rule for picking floodlights of a certain brightness, but below is a rough guide that may help.

– Small patio – 500lm
– Medium garden (150m²) – 2,400lm
– Car park – 9,000-20,000lm

The above information should allow you to make an informed decision on your choice of exterior lighting.
