Changing a light bulb any of the easiest yet best ways of reducing energy consumption and cutting carbon exhausts. Simply replacing an amoureux bulb with an energy saving alternative can cut electricity use by upward to 80%. The Energy Saving Trust
believes that lighting accounts for 8% of household electricity costs in the UK which means there is great possibility of substantial energy and money led light bulbs savings.
The seemingly straightforward
activity of choosing a light bulb has however become somewhat of a mine field lately. The variety of light bulbs and lighting technology on the market and the fast pace of development in the industry is both cause for consumer celebration and extreme caution.
Greater range of choice gives consumers unprecedented freedom but also means it is more important than in the past to choose the right light bulb for the right software. Comparing lumens per watts values is a fairly easy way to identify the most "light"
efficient lamp in conditions of brightness. But for work out which light type is best for a specific application in conditions of energy efficiency the next things need to be considered: wattage, lamp life, daily use, light cost and lighting result required.
The best way to do this is with an energy saving calculator. By entering specific beliefs you can compare your present light bulbs with those you are considering replacing them with and
make an educated lights decision based on a power saving forecast.
So what energy savings options are there? Most people are talking about Light Emitting Diodes (LED) at the moment and rightly so given their dramatic advances recently in lumen efficacy
and light fixture life. Depending on the application, compact fluorescents (CFL) and halogen energy investors are also a highly effective way to save energy. Within most cases a retrofit replacement lamp can be found and energy saving bulbs can be purchased
in all the normal limit types including bayonet, Edison screw, GU10 and many more.
LED is regarded as the most effective form of low energy lighting available and many in the industry expect it to have a market share of around 50-60% by 2020. Unlike
some other types of lighting, particularly incandescent, LEDs are efficient because almost all of their electric power goes towards the light-production process. A great incandescent bulb, for example , requires its filament to glow white-hot before producing
obvious light, thus heat is produced as a not economical by-product which uses around 80% of electrical power. In comparison, less than 10% of LED electrical usage is emitted in the form of heat.
LEDs produce light by the Electroluminescence. This
is the phenomenon where by light is emitted from a material when an electrical current is passed through it. An LED chip is made from a material heavy with 'impurities' to produce a p-n junction between two sorts of semiconductors and electron openings. Electrons
can only movement one way across the junction so that as they do they fill electron slots creating their degree of energy droplets and the release of photons (light).
