LED lighting for workplace car parks

A workplace car park can be one of the busiest areas of a business site, with employees, visitors and delivery vehicles using it throughout the day and often in darkness during the winter months.

Good car park lighting is important for safety and security, but it can also have a significant impact on an organisation’s energy consumption and maintenance costs.

Upgrading an existing workplace car park to LED lighting can therefore be as much about replacing old light fittings as it is about creating a safer, more efficient and more cost-effective outdoor environment.

Why is good lighting important in workplace car parks?

A workplace car park needs to accommodate both vehicles and pedestrians. While vehicles are manoeuvring through the site, employees may be walking between their cars and the building. Visitors may also be unfamiliar with the layout.

For businesses, effective car park lighting is therefore an important part of providing a safe and accessible workplace. Poor lighting can make it harder to see pedestrians, vehicles, kerbs, obstacles and changes in level. Dark areas can also affect people’s perception of safety.

The Health and Safety Executive (HSE) states that workplace roads, manoeuvring areas, yards and pedestrian areas should have suitable and sufficient lighting.

What are the benefits of LED car park lighting?

Lower energy consumption

One of the biggest reasons businesses switch to LED lighting is the potential reduction in energy consumption.

LEDs can provide the required amount of light while using less energy than many older lighting technologies. This can be particularly valuable for car parks that operate for long periods or remain illuminated throughout the night.

The potential saving will depend on the existing lighting, operating hours, number and wattage of fittings, and the proposed LED system. A professional lighting assessment can help establish the likely savings.

Reduced maintenance costs

Car park lighting can be expensive and disruptive to maintain, particularly when fittings are mounted on high columns or in difficult-to-access locations.

LEDs generally have long service lives, reducing the frequency of lamp replacement and associated labour and access costs. For businesses, this can mean lower ongoing maintenance costs and less disruption to employees and visitors.

Better visibility and safety

Good visibility makes it easier for drivers to identify pedestrians, other vehicles, parking bays, kerbs and potential hazards. A well-designed LED lighting system can provide more consistent illumination across a car park, helping to reduce poorly lit areas and shadows.

Improved security

Good lighting can help employees and visitors feel more comfortable when walking to and from their vehicles, particularly early in the morning, late in the evening, or during the shorter days of autumn and winter. It can also make it easier to identify people, vehicles and potential hazards.

Lighting can support a wider site security strategy too. Better illumination can help CCTV systems capture useful images and make entrances, exits and pedestrian routes easier to monitor.

Smart controls can reduce energy use further

Modern LED lighting can be combined with intelligent controls to avoid operating every fitting at full output when the car park is quiet.

Depending on the site, businesses could use a combination of presence or motion sensors, daylight sensors, time-based controls, dimming and zonal lighting controls.

Choosing the right LED fittings

Not every LED fitting is suitable for an outdoor workplace car park. Look at environmental considerations including exposure to rain, dust, impact and temperature change, and the type of fitting most suitable to these. Take into account:

• IP rating: Provides protection against the ingress of solids and water.
• IK rating: Indicates resistance to mechanical impact and can be important where fittings could be vulnerable to accidental or deliberate damage.
• Light distribution: Good optics help direct light where it is needed, reducing glare and unnecessary light spill.
• Colour rendering: Good colour rendering can help people distinguish objects, vehicles and individuals more easily.

How much lighting does a workplace car park need?

There is no single lighting level that is appropriate for every workplace car park. Requirements depend on factors such as the type of site, traffic levels, pedestrian activity and how the area is used.

BS EN 12464-2:2024 – Light and lighting. Lighting of workplaces – Outdoor workplaces is the current standard covering lighting requirements for outdoor workplaces. It considers factors including illumination, uniformity, glare and visual comfort.

Don’t forget pedestrian routes

The car park shouldn’t be considered in isolation. Employees and visitors need to get safely from their vehicles to the building, so pedestrian routes, crossings, entrances, steps, ramps and changes in level should also form part of the lighting design.

Can LED car park lighting save businesses money?

Potentially, yes. The financial benefits of an LED upgrade can come from several areas:

• Reduced electricity consumption
• Lower maintenance requirements
• Fewer replacement lamps and fittings
• Reduced labour and access costs
• Greater control over operating hours
• Potentially lower carbon emissions

The return on investment will depend on the existing installation and proposed system. A useful starting point is to assess the number and type of existing fittings, their wattage, operating hours, maintenance history and energy costs. Then compare these figures with the proposed LED installation.

For businesses still operating older lighting systems, an LED upgrade could provide an opportunity to reduce running and maintenance costs while improving the workplace environment. However, merely replacing existing fittings with LED equivalents may not deliver the best possible result.

A professional assessment can consider the car park layout, lighting levels, uniformity, glare, pedestrian routes, operating hours, energy consumption and opportunities for intelligent controls. Contact our team to find out more.
