LED lighting – the facts
Energy efficiency

LED lighting offers the highest energy savings of any lighting source on the market and we’ve plenty of real-life examples to prove it. Typically the replacement of 400W conventional HID light sources with our 150W LED High Bays will deliver immediate energy savings of 60+%. If the LEDs are combined with dimming and proximity sensors these savings are even higher. The result is that the lights end up paying for themselves several times over in their lifetime.

Reduced maintenance

Industrial lighting is costly to operate and a major drain on maintenance resources for most organisations. As a plant manager in an industrial environment, especially offshore or in a hazardous area such as a refinery or petrochemical plant, you may be entrusting your lighting maintenance to a highly paid electrician and regularly incurring the additional need for hot permits, gas detectors, specialist rope or scissor lift access, safety officers and more.

With its exceptionally long lifespan our LED lighting can ensure that you vastly reduce your maintenance burden. Dialight LED lighting is rated L70 for 100,000 hours, meaning that it will still be producing 70% of its original lumen output at the end of this period of operation. There will be no burnout or end-of-life failure and no need to open the fixture during its lifetime; instead the output just gradually fades over time, allowing you to anticipate and plan maintenance on a much reduced scale.

All our LED fittings carry a five-year continuous performance warranty on the complete fixture as standard with a ten-year warranty option also available. As they can be expected to last ten years or more, your maintenance really can be vastly reduced or eliminated with our LED lighting solutions.


Switching to energy efficient LED lighting is one of the simplest and most immediate ways your organisation can cut its CO2 emissions to protect the environment and be seen to support sustainability in its operation.

Our LEDs typically use one third of the energy of alternative light sources, such as high pressure sodium or metal halide, so while you cut your energy bills by two thirds, your carbon emissions drop by the same amount.

On average by replacing 100 HID high bays with 100 Dialight DuroSite LED High Bays you can reduce CO2 emissions by 125 tons per annum (12/7 operation). And as LED light fixtures are mercury-free and contain no hazardous materials, they are environmentally safe and recyclable, so LED lighting is undeniably the sustainable choice.
