What are LED bulbs great at? LEDs are still the most expensive type of light bulb you'll see in the shops, but they do have advantages over the other types of bulbs. LEDs are the most energy-efficient bulbs. They use 90% less energy than traditional incandescents and can sometimes pay for themselves through energy savings in just a couple of months. So while the upfront cost might be high, you'll notice the difference in your annual energy bills. By contrast, Compact Fluorescent Lamps (CFLs) use 60%-80% less energy than incandescents, while halogens use 20-30% less. LEDs claim to be ultra long lasting - lasting for 25-30 years, depending on which one you buy and how you use it. LEDs give out their light almost instantly when you flick the light switch, so you don't have to put up with dim light while they get going. Our tests have found that LED and halogen bulbs work fine in low temperatures, whereas CFLs don't.
The Advantages of LED Lights for the Environment Energy Efficient LED lights are up to 80% more efficient than traditional lighting such as fluorescent and incandescent lights. 95% of the energy in LEDs is converted into light and only 5% is wasted as heat. This is compared to fluorescent lights which convert 95% of energy to heat and only 5% into light! LED lights also draw much less power than traditional lighting; a typical 84 watt fluorescent can be replaced by a 36 watt LED to give the same level of light. Less energy use reduces the demand from power plants and decreases greenhouse gas emissions. No Toxic Elements LED lights contain no toxic elements. Most offices currently use fluorescent strip lights which contain noxious chemicals such as mercury. This will contaminate the environment when disposed of in landfill waste. Disposal has to be arranged through a registered waste carrier so switching to LED avoids the cost and time implications required for compliant disposal – and helps to protect the environment from further toxic waste. Less Lights Needed LEDs have a better quality of light distribution and focus light in one direction as opposed to other types of lighting which waste energy by emitting light in all directions, often illuminating areas where light isn’t required (such as the ceiling). This means that less LED lights are needed to achieve the same level of brightness given off by fluorescents and incandescent lights. Fewer lights will reduce energy consumption and will therefore be a benefit to the environment. Life span A longer life span means lower carbon emissions. LED Lights last up to six times longer than other types of lights, reducing the requirement for frequent replacements. This results in using fewer lights and hence fewer resources are needed for manufacturing processes, packaging materials and transportation.
What are LED light bulbs? LED lights have been hailed as the future of home lighting, as they use very little energy, claim to last a very long time and, unlike regular energy-saving bulbs, they are instantly bright when switched on. Early LEDs were limited by high prices and relatively low light output, but the technology has developed rapidly in recent years, and you can now get bright, efficient LED bulbs that replace 100W old-style bulbs and look just like a traditional bulb. What's more, prices are getting lower all the time. LED bulbs differ from traditional incandescent bulbs in the way they produce light. While old-fashioned incandescent light bulbs passed electricity through a thin wire filament, LEDs produce light through the use of a semi-conductor that emits light energy when an electrical current is passed through it. This way of producing light is also different from regular energy-saving bulbs, which pass energy through mercury vapour to create UV light. This is then absorbed by a phosphor coating inside the lamp, causing it to glow. #led bulb in faridabad
