In every home, nearly thirty percent of the total electricity bill is used in lighting. So, if you replace your inefficient halogen bulbs with LED bulbs, you can significantly reduce energy consumption and save more money. LED lights are a lot more cost-efficient and energy-efficient compared to halogen lights that is why they are more ideal for downlights, kitchen lights, and outdoor fixtures.
Anyone who's ever installed downlights knows that you need to fit a large amount of them to achieve sufficient lighting levels. If you are using energy guzzling halogens, this creates a major problem with energy efficiency. Halogens use fifty watts each and you will most likely need to install one square meter. This means that an average size room of six meters by four meters would require twenty four downlights. The energy consumption would be twelve hundred watts! This is like leaving the kettle switched on for long periods of time.
LED bulbs provide energy savings of ninety percent. Using a five watt or seven watt LED instead of a fifty watt halogen will provide the same lighting effect and will have a substantial effect on your electricity bills. Twenty four downlights would only use one hundred and sixty eight watts.
There are four main types of lights that are used in the home, each one is unique. The first and earliest design after candle and gaslight is incandescent. Incandescent has been around for over one hundred years and creates light by running electricity through a filament. This filament heats up and produces light while it is hot. Because of such process, about ninety percent of the energy used is only converted into heat. The remaining ten percent becomes converted into light. So, if you use incandescent light bulbs for your downlights and outdoor lights, you will waste energy. For this reason most incandescent bulbs are either being phased out or have already been taken within the EU.
The average life of these lights is only about one thousand hours, so frequent replacement will be necessary. They are also not practical choices for hard-to-reach areas such as high ceilings.
Halogen lights are similar to incandescent and have a similar life cycle. Halogen light is created by heating a small amount of glass inside a capsule. Again around ninety percent of energy is wasted in heat. It is widely anticipated that halogens will be also be rented by 2016. This alone will say the UK billions in electricity costs per year.
In addition, incandescent lights and halogen lights are dangerous and fire hazards. The filaments inside halogen can rise up to 2,500 degrees C while the bulb can rise up to 500 degrees C. So, if there is a piece of insulator touching the light fitting, there could be a fire. If you want to prevent fire from starting, opt for cooler lights such as LED light bulbs or compact fluorescents.
LED produces light by making use of diodes instead of heated filaments or gas. They can be as small as two millimeters, making them ideal for fitting into compact areas and hard to reach places. They can also last for a long time – ranging from twenty five to seventy five thousand hours. This equates to around twenty years as you would base the life expectancy on around six hours per day usage.
With LED bulbs, you can be sure of your safety even if you use your downlights, kitchen lights, and any other lighting fixtures. Although halogen light bulbs provide a super bright, crisp lighting effect the technology is dated.
When it comes to energy saving, nonetheless, noting is better than LED. They are your best options for downlights, kitchen, garden, and even emergency lights. They use very little energy but give a bright lighting effect. LED bulbs are not perfect because as they are a bit pricey, however the energy savings are plenty and far outweigh the initial costs. In the long run, you will get more satisfaction, say yes to LED and no to halogen!
