The latest LED bulbs emit excellent quality light and are now available in all shapes and sizes to replace traditional light bulbs. They provide great energy performance and are much better than some of the earlier versions that left a lot to be desired in terms of performance, life expectancy and light quality. LED light bulbs are one of the easiest and lowest cost ways to introduce energy efficiency into your home.
Benefits of LED Lighting
What are the Main Benefits of LED Light Bulbs?
Energy Savings : LED light bulbs use up to 90% less energy than traditional light bulbs such as incandescent and halogen.
Money Savings: By reducing electricity consumption by up to 90%, this can result in some great savings on your energy bill. The savings generated will depend on the quantity and type of bulbs that you replace, and the specification of the new replacement lamps.
How much can I save by switching to LED Bulbs?
LED lighting products are no doubt one of the simplest and lowest cost methods to reduce electricity consumption and cut the amount spent on your energy bill. On average an LED bulb will use 80-90% less electricity when compared to an equivalent halogen or incandescent light bulb. Lets look at some examples…
Example of Saving Electricity by using LED Bulbs
A 7 watt LED light bulb can be used to replace a 50 watt halogen light bulb. The 7 watt LED demonstrates the same brightness as the 50 watt halogen, yet because it uses low energy technology it consumes 86% less energy. So what does that mean in pounds and pence?
50 Watt Halogen Bulb
- This bulb uses 55 kilowatt hours (units) of electricity per year if switched on for 3 hours per day.
- That’s an annual running cost of £7.15. (Unit cost £0.13 pence per unit)
7 Watt LED Bulb
- This bulb will use 7.6 kilowatt hours (units) of electricity per year if switched on for 3 hours per day.
- That’s an annual running cost of £0.98 pence. (Unit cost £0.13 pence per unit)
That’s a saving of £6.17 per year. In a typical house with 15 light bulbs that’s an annual electricity cost saving of £92.55, or £462.75 over a 5 year period.
What is an LED Light Bulb and How do they Differ from Regular Light Bulbs?
LED light bulbs use different technology to generate light than regular light bulbs. Regular light bulbs heat a filament which then glows white hot in order to emit usable light. Unfortunately this isn’t a particularly energy efficiency process, due to the fact that most of the energy used is wasted in heat.
LED light bulbs instead use small LED chips in order to generate light. LED chips are a semi-conductor device that emit light via the movement of electrons when an electrical current is passed through. This process doesn’t generate much waste heat, and therefore nearly all of the energy used to power the device is converted into useful, visible light. This means that LED light bulbs use up to 90% less energy than a regular halogen or incandescent bulb in order to produce the same amount of light.
