Energy Efficient Lights For Your Home
A typical household consumes 15% of its electricity bills on lighting. With the current improving technology, many engineers are working to produce bulbs that are more effective, safe to use, energy efficient and hence less costly. Many households are always struggling to keep their electricity bills as low as possible.
Efficient lighting involves using bulbs and light fittings that consume the least amount of energy. Homes can cut their energy consumption on lighting by 50% and above if they make smart lighting choices and adopt efficient lighting technologies. To cut on their energy bills, many homes are shifting to the use of energy efficient bulbs like halogen, fluorescent and light-emitting diode (LED) bulbs.
Advantages of using energy efficient lighting
Energy efficient lighting can help a home to significantly cut on their electricity bills. This is because they use around 25%-80% less energy hence helping a household save money from energy bills. Additionally, energy-efficient light bulbs can last much longer than traditional incandescent.
LED produce 3.4 btu’s/hour as compared to 85 for traditional incandescent bulbs. LED, therefore, cause very minimal heat build-ups in a house. Traditional incandescent bulbs heat up and emit a lot of heat in the room. LED bulbs reduce this heat build-up hence reducing the cost of air condition in a home.
Although LED bulbs are initially costly, the costs are recovered over time in energy savings. Initially, LED bulbs were used in commercial buildings which are large and attract high replacement and maintenance costs. However, over the years, the cost of LED bulbs has considerably gone down. In order to install these lights you’ll need a qualified electrical contractor. Jeremy Highland from Pro Electrician Melbourne was quoted as saying “Installing LED lights is a lot cheaper than many home owners think. It costs around $30 per light and the price comes down the more you install”.
Different Types of Energy Efficient Lights
There are several energy-efficient lighting options to choose from. The popular options adopted by many households are light-emitting diodes (LEDs), compact fluorescent lamps (CFLs) and halogen incandescent.
Halogen lights are used for task lighting, automobile headlamps, sconces, recesses and torchère lamps. Halogen bulbs, like incandescent bulbs contain tungsten filaments. However, unlike incandescent bulbs which have nitrogen or argon gas trapped in silica-based glass, halogen bulbs have halogen gas trapped in quartz glass. The gas and the glass enable the bulb to produce a lot of energy per energy unit hence making them longer lasting and energy-efficient. Halogen lights come in several colors and shapes and can also be used with dimmers.
LED is a semiconductor device which can change electricity into light. The technology imitates a light sandwich i.e. a chemical engulfed between two thin glass layers. When powered by electricity, an electronic signal cause electrodes to light up which eventually react to the chemical and produce a nearly ultraviolet light.
Compared to incandescent lights, LEDs are able to produce almost 100 times more light for up to 100,000 more hours. The long life of LEDs makes them the best choice for use in traffic lights, flashlights, exit signs and car dashboards. Although they are initially more expensive compared to other bulbs, their long life plus low power consumption makes them cost-efficient bulbs.
Light engineers and manufacturers are making LEDs more usable and adaptable in residential settings. Presently, LEDs are able to indicate when DVD and CD players, telephones, remote controls, TVs and other devices are on. They can be installed in staircases, under counters and along walkways.
LED holiday lights consume 0.04 watts for every build compared to 5 watts for every traditional two-inch bulb. In a period of 30 days, 500 LED lights on a holiday display or a Christmas tree cost around $0.19 worth of electricity. In addition to reducing energy costs, consumers may find it unnecessary to replace the bulbs because they last over 60,000 hours. Compared to traditional holiday lights, LED bulbs do not emit heat hence reducing heating of a room and reduce fire hazards.
Compact Fluorescent Light Bulbs
Compact fluorescent light bulbs consume up to 75% less energy and last up to 10 times longer than traditional incandescent bulbs. Despite their high costs, they help save money in the long run.
Additionally, CFLs do not produce heat hence do not cause heat build-ups in a room. They produce light when current passes through mercury vapor and produces ultraviolet light. It is this ultraviolet light that makes the bulb to glow after reacting with a thin layer of phosphorous inside the outer casing of the glass.
Many households are increasingly adopting efficient lighting in their homes. This is so due to the advantages that come with the use of efficient lighting compared to traditional lighting systems. Efficient lighting systems have become the targets for many homes looking working to reduce electricity bills.
Additionally, efficient lighting system causes very little harm to the environment and are also long lasting. Although many of the efficient lighting systems are expensive compared to their traditional counterparts, these costs are recovered in the long run through reduced energy bills and long lifespan.
