Cost Saving Benefits
The main advantage of using LEDs is the cost saving. There are several areas where money can be saved:
- Electricity bill - LEDs use significantly less energy than traditional bulbs, because they create significantly less heat (Traditional incandescent bulbs lose up to 90% of their power creating heat which is wasted). Therefore your electricity bill will be less than if using other types of bulbs. In general, the cost of lighting in a household is 20% of the overall electricity bill. For a more specific analysis of your own situation, please use our energy calculator to determine your savings.
- Replacement bulbs – The average lifespan of a LED is 25,000 hours, compared to 1,000-2,000 hours for an incandescent bulb, 2,000 hours for a halogen bulb and 4,000 hours for a CFL bulb. Therefore, you will save money as bulbs do not have to be replaced as often.
- Maintenance costs – For commercial premises, the cost of maintaining and replacing the lights can be very expensive. With LED lights, once they have been installed, there will be no additional maintenance costs for the life of the product.
Although the initial costs of the LED bulbs are higher than traditional bulbs, these costs may be recouped very quickly
Environmental Benefits of LED
There are several ways that using LEDs can have a positive impact on the environment:
- Lighting counts for 20% of an average electricity bill (up to 80% in retail / commercial applications) and therefore it has a large impact on the carbon footprint of a home or business. LEDs provide an excellent opportunity to significantly reduce carbon emissions and help the environment. The Energy Savings Trust has said that if everyone in the UK changes their lights to LEDs, enough energy will be saved to light 5 million homes.
- LEDs provide a directional light source, which significantly reduces light pollution.
- LEDS operate at low temperatures and so by reducing the heat pollution, there will be a decrease in the need for secondary systems such as air conditioning.
- As LEDs are mercury free, they do not require any special re-cycling disposal.
The UK Government has several on-going initiatives to help reduce the carbon emissions in the UK. Please refer to the Carbon Trust website www.carbontrust.co.uk and the Energy Saving Trust at www.energysavingtrust.org.uk.
Health and Safety
- There are several reasons why LED bulbs are advantageous from a health and safety perspective: LED bulbs are more durable than traditional bulbs as they have no fragile parts. They also contain no mercury, so if the bulb breaks, there is no risk of contamination. (If a CFL bulb shatters, there are safety guidelines which must be followed).
- LED bulbs generate very little heat and are therefore safer around the home. Because they operate at lower temperatures, they will not cause scolding to the skin and the fire risk associated with overheated incandescent bulbs is not an issue with LEDs.
- In an industrial environment, as LEDs are very strong and durable, they are used in areas which are more susceptible to heavy vibration (around machinery). LEDs also work well in low temperatures and can be used in cold industrial environments.
- LEDs do not generate any UV (ultraviolet) or IR (infra red) radiation. Therefore they are very well suited environments such as museums.
LEDs are very small and so the bulbs themselves can also be small and match the size of current halogen bulbs. CFL bulbs are larger in size and are not so aesthetically pleasing.
