LED Light Bulbs Energy Efficient Lighting
The total cost of electricity used over the lifespan of a single incandescent bulb is 5 to 10 times more than the original purchase price of the bulb itself. LED; Light Emitting Diode bulbs have totally revolutionized energy-efficient lighting.
LED bulbs are compact, reliable, and very efficient bulbs. New and emerging LED bulbs are clustered with diffuser lenses that have broadened the applications for LED use in homes. LED technology is rapidly advancing with many new bulb styles available. Initially, more than CFL; Compact Fluorescent Lights, LEDs offer better value for money because the last longer. It is also worth noting that the price of LED bulbs is going down every subsequent year as the manufacturing technology continues to improve.
LED is a highly energy efficient lighting technology that has the potential to fundamentally change the future of domestic and commercial lighting the world over. Domestic LEDs especially Energy-Star rated products use close to 75% less energy and will last 25 times longer than incandescent light bulbs.
More usage of LED light bulbs has the exponential potential to accelerate on savings on energy. By 2027, global usage of LEDs can shave off 348 TWh compared with non-LED use. This is an equivalent of over mega electric power producing plants; 1,000 megawatts each, annual output.
How different are LEDs?
LED lighting is very different from other light sources including CFLs and incandescent bulbs. The key differences include the following:
- Light source: LED light bulbs are the size of a fleck of pepper. A mix of green, blue, and red LEDs will typically make white light.
- Heat: LEDs emit very little heat. In comparison, CFLs release about 80% and incandescent bulbs release 90% of their energy respectively as heat.
- Direction: LEDs emit light in a specific direction which reduces the need for reflectors and diffusers that have the potential to trap light. This unique feature in LEDs makes them more efficient for many uses like task lighting and recessed downlights. Other types of lighting must have their light reflected towards the desired direction with over half of their light never leaving the fixture.
LED light bulb are available in a wide variety of industrial and home energy saving products with the list growing every year. The current rapid development of LED technology has lead to the production more bulbs with improved manufacturing efficiency, better lighting, and lower end-user purchase price.
These are some of the standard LED products:
- Commercial and industrial LED lighting fixtures.
- Kitchen under-cabinet LED lighting fixtures.
- Recessed downlights.
- Task lighting in laboratories, hospital theaters, and repair shops.
- LED replacement bulbs.
- LED holiday lights.
Benefits of LED light bulbs
- Long-lasting: -LED bulbs last up to 10 times longer than CFLs and conventional incandescent bulbs.
- Durable: - Because LEDs do not have a filament and are very solid, they do not damage easily under the same circumstances that regular incandescent and CFLs get damaged.
- Cool: - LED bulbs emit close to 90% less energy than CFLs and incandescent bulbs.
- Mercury free: There is no mercury used to manufacture LEDs.
- More efficient: LED light bulbs use 2-17 watts of electric power with better and brighter light, save money on replacement costs since they last longer thereby reducing your energy bill significantly.
LED light bulbs are the ultimate energy saving domestic, industrial, and commercial lighting solution. They are readily available, safer, sturdier, longer lasting, and very easy to install.
