You may not have heard of led energy saving light bulbs but you well in no doubt aware that over the past few years the Department of Energy &Â Climate changeÂ and the energy savings trust have been urging households to start making use of energy saving light bulbs due to the fact they are good for the environment, cheaper to run and last longer too. LED energy saving light bulbs are a relatively new comer on the energy saving light bulb market and as of yet have generally been overlooked by the government. In this post we’ll provide you with the vital facts as to why LED bulbsÂ are an optimal solution to improving your home and office lighting energy efficiency
what are LED energy saving light bulbs?
Light Emitting Diodes (LED) are a form of solid state lighting that is extremely efficient and long lasting. While incandescent and Compact Fluorescent Lamps (CFL) lights consist of filaments in glass bulbs or bulbs that contain gasses, energy saving LED light bulbs consist of small capsules or lenses in which tiny chips are placed on heat conducting material.
Low energy usage
LED bulbs only use around 10% of the energy of traditional bulbs, meaning a 10W LED bulb provides the same amount of light as that of an equivalent 100W bulb!.Â This dramatically reduces your energy consumption over the course of the bulbs lifetime, couple this with the factÂ that they are also long lasting, so a further reduction in replacement costs.
The average projected hours of light an incandescent bulb can provide is between 750 to 2000 hours and a compact fluorescent bulb provides between 8000 to 10 000 hours. LED bulbs will generally provide between 20 000 to 30 000 hours of light. Typical lifetime is defined as the average number of hours until light falls to 70 percent of initial brightness, in lumen. LEDs will typically fade gradually .
LED energy saving light bulbs contain no glass components therefore they are not vulnerable to vibration or breakages like conventional bulbs. LEDs are thus well suited for use in areas like sports facilities, child play centres or any area which are exposed to abnormal lighting use.
Conventional light bulbs waste most of the their energy as heat i.e. an incandescent bulb gives of 90 percent of its energy as heat, a compact fluorescent bulb will waste 80 percent as heat.
LED energy saving light bulbs provide instantaneous light and do not need to warm up like CFLs, which have a warm-up period lasting anywhere from a few seconds to a couple of minutes, during this period they are not as bright as they eventually become. This usually means that with CFL’s you may need to leave the lights on longer than what they were actually required. LED bulbs turn on instantly, reaching full brightness immediately.
Switching to LED lighting technology is one of the easiest ways to drastically reduce costs with the added benefits of helping to conserve the environment. In most households and office buildings lighting costs can be one of the biggest addition to the monthly energy expenditure, especially during the winter months in the northern hemisphere. Replacing your current lighting with led energy saving light bulbs alternatives you will gain from an immediate reduction in energy consumption. In some cases the savings can amount to as much as the savings can be as much as 82% and at a time when energy prices are increasing year on year this will quickly impact your costs.
It is important to understand that energy saving lamps contain mercury and other hazardous waste products which must be specially disposed of, whereas light emitting diodes are non-hazardous and therefore recyclable. LEDs have long lifetimes and are often retrofit, leading to a reduction in the quantity of old fittings and lamps being discarded to landfill. LED energy saving light bulbs greatly reduce energy consumption and thus reduce carbon emissions. LEDs give long lasting light with far less negative impact on the environment, helping your organisation to comply with environmental legislation.
