Forget about the Watts
LED lighting products have drastically increased in brightness, style, and reliability during 2013, while becoming more affordable in the process. Gone are the days of the 60W bulb now you can produce the same amount of light using only 4W of power.
So how do you know how bright your new bulbs will be?
Over the years people have become accustomed to using incandescent light bulbs, and have an understanding of how much light would be produced by say a 40, 60 , 80 or 100 Watt bulb. However now we live in a world with an ever increasing demand for electrical power, manufacturers have found new technologies such as LED bulbs to produce a large amount of light for a low amount of power. This has left a lot of people very confused about what they are buying.
If you go to a shop to buy a new collection of LED bulbs, the easiest way to know how bright they will be while just looking at the box is to check the Lumen rating. What’s a lumen you ask, well a lumen is a standard unit of light as perceived by the human eye, so instead of using units of power to talk about the brightness of a bulb now we use a measurement of light.
To the left you can see a little diagram depicting how an LED bulb compares with a standard incandescent bulb. As you can see you can get the same amount of light for a tenth of the power.
Low Energy + Instant full power lighting
We have had a few customers who were put off of the idea of the LED bulbs due to being told that they were energy saving. The term energy saving instantly conjured the image of the CFL that came on the market a few years ago, they take a long time to light to full brightness and can be quiet impractical. These slow building lighting energy saver bulbs are thankfully a thing of the past, with the new range of LED bulbs you can save energy (and therefore money) without compromising on brightness and providing an instant full light.
Do I have to change my light fittings?
Some lighting designers such as Mantra Lighting have developed new ranges of lights that come with SMD LED arrays pre built into them, which should last 15 – 20 years, with these you cannot change the bulb at any point.
Although the majority of LED light bulbs come adapted to fit all standard incandescent and halogen light fittings. So you don’t have to change anything other than the bulbs in your home to benefit from LED lighting.
We stock LED golf and candle bulbs with E14, E27 and B22 fittings, as well as stocking R50 and R63 LEDS and GU10, GU5.3, G9, G4’s all of which use between 3 – 5 Watts of power
How much money will I really save?
As you will be aware LED bulbs require very little power, they also last a very long time. Most manufacturers state their bulbs will last between 15 – 25 years, that’s almost quarter of an average person’s life span.
In comparison halogen bulbs need changing every 2 – 3 years, and as you can imagine manufacturers have set the price to reflect this difference.
A halogen G9 28W cost £ 1.50
A LED G9 2.5W costs £ 9.95
The LED will last 15 years. The halogen 2 years so it would cost you £11.25 to buy 15 years’ worth of halogen G9 bulbs
Let’s say you live in a house with ten rooms, in each room there is one central light fitting that has 3 bulbs on it. If each of those bulbs is a 40W bulb then you would be using a total of 1200 Watts per hour (if you had all the lights on at once) based on having all the lights on for 6 hours per night that works out at £359.57 per year.
Using the same amount of lights for the same amount of time with LED bulbs fitted you would be looking at an hourly power consumption of only 120 Watts, bringing the total cost for the year to only £35.95
So that is a saving of £323.62 per year (this figure is just the value of the electricity you save)
*based on unit rate of 13.72 pence per KWh
The total cost of 30 bulbs (the amount required in our imaginary house) would be £298.50
So if we offset that against the first years electricity savings, we can see that we have covered the cost of the bulbs and still saved a further £25.12 in the first year alone
So when you go to buy a new light fitting for your home, you don’t need to worry about asking if it is LED compatible, as you can buy LED bulbs for all commonly used lamp fittings. Also you don’t need to worry about what wattage bulbs the light fittings can house. With these new LED bulbs you can have instant lighting and incredibly bright lights in your home that all use less that 5W a bulb. LED technology is the way forward for lighting our homes.
