The benefits of switching to LED lighting

Home - Energy Efficiency - The benefits of switching to LED lighting

Why switching to LEDs needs to be top of your energy saving list

The global issue of carbon emissions is not a new topic, and yet many businesses fail to realise their own contribution to global warming. The UK’s CO2 emissions in 2019 stood at an estimated 354 million tonnes of CO2 with non-domestic buildings accounting for almost half of the country’s emissions.

CO2 is responsible for 64% of manmade global warming, contributing to the global average temperature being 0.85ºC higher than it was in the late 19th century. Scientists warn of a threshold of 2ºc temperature increase, at which point the world is likely to see catastrophic changes in the global environment.

A comprehensive design of the lighting system can save on energy consumption by ensuring an efficient level of light is provided without excess lighting being used, harvesting daylight or using dimming where possible to save energy.

Complete cost of ownership is significantly reduced when you switch to LED lighting and the Hilclare specialists have broken down these benefits for us:


The efficiency of a luminaire is the ratio of the light output from the fixture over the light output of the source and is typically calculated as a percentage. LEDs use around 70% less energy to operate than their incandescent counterparts, which means instant savings on your energy bills along with up to 95% savings on your maintenance budget.


The efficacy of a luminaire is the ratio of light output (lumens) to energy input (watts) and so is measured in lm/W. Where incandescent fittings typically operate with an efficacy of 16 lm/W, LEDs can reach up to 126 lm/W, giving excellent performance using less energy. This enhanced efficacy of LED lighting has led to costs of older lighting technology increasing due to decreasing demand for non-LED technology.


Another benefit of not using a filament in the fitting is that LEDs are inherently more durable. Using fittings with quality components such as aluminium cast housing will also ensure that their lifetime potential reaches full capacity.


The aluminium cast housing of modern LEDs such as Hilclare’s Bandera PRO ensures an excellent heat dissipation and as a result long lifetime is achieved of up to 100,000 hours L80B10 – at least 50 times longer than the typical incandescent fitting. This also means a reduction in WEEE charges as LEDs need replacing less frequently, and so there is less waste lighting equipment produced, which is another cost saving that you can benefit from after switching to LED.

Heat Wastage

By using aluminium cast housing for the fitting of LED luminaires, this also ensures an excellent heat dissipation in comparison to incandescent lamps. The incandescent fittings typically lose around 95% of their energy as heat, with only the remaining 5% being output as light. As LEDs do not produce infrared heat, they are a much safer option as the lamp glass does not heat up in the same way that incandescent lamps do.

This can prove especially valuable in temperature-controlled environments where LEDs do not impact the temperature of the room in the same way incandescent fittings would. This can save even more on your energy bills where air conditioning does not need to contend with heat being produced from the lighting.

Environmental Impact

When reviewing the benefits of switching to LEDs, we often look at how this can benefit ourselves, our business and our energy bills but we must also acknowledge the monumental benefits to the environment as well. Primarily, LED fittings use less energy to produce the same level of light as with incandescent lamps and less heat is released unnecessarily into the atmosphere. In fact, it is estimated that over half a billion tonnes of CO2 is saved each year globally as we switch to LED solutions.

The lifetime of LED luminaires is also a significant contributing factor to their reduced environmental impact. As the fittings last longer, less production, manufacturing and transport is required. This then naturally leads to less waste lighting that needs to be recycled or sent to landfill, as the fixtures do not need to be replaced as frequently.

energy saving environmental impact


The quality of light produced ensures LEDs are the optimum solution for educational and healthcare environments as they can see significant psychological benefits on students and patients.

Their durability also makes them ideal for lighting requirements in hazardous areas such as in high temperature, explosive environments or areas with water or high volumes of dust. This can involve applications such as pulp and paper mills, warehouses and tunnels. Dust resistant fittings also make them suitable for environments that involve food preparation where they need to comply with HACCP IFS BRC food industry standards.

The lifespan also makes them ideal for emergency lighting where they are often installed and subsequently require minimal maintenance. The range of emergency light fittings offered by Hilclare can provide solutions to suit a range of specifications for interior public areas.

LED fittings are often utilised in outdoor settings for their efficiency where essential illumination is required. This can include gardens, doorways and walkways, to larger exterior environments such as dockyards, freight terminals and substantial architectural structures.

LED energy saving applications

Switching to LED can bring serious savings to your business and significantly help slow down rising temperatures caused by greenhouse gases. Speak to our specialists to discuss how we can help you to start saving money.

To further improve the efficiency of your building, have you considered installing an Energy Management System (EMS)? Our sister company Pilot Group EMS can help you save up to 40% on your energy bills using an advanced energy management system, designed to set new industry standards and increase customer savings. The intelligent energy management system responds to these variable factors to ensure that the heating in any zone never goes above the target temperature.
