Are LEDs energy-efficient?
Modern Physics, Palisa Tuladhar
REASON TO CHOOSE THIS TOPIC
We all know the importance of Green environment and conservation of energy. Light, being one of the most important source of our daily life without which we all be in darkness. The use of light sources are growing rapidly. Along with the growth in use of ight, there is high risk in the growth of harmful gases emitted by different kinds of light sources. LED is a highly energy efficient lighting technology, and has the potential to fundamentally change the future of lighting. The use of LED lighting has the greatest potential impact on energy savings because LEDs could save about 348 TWh (compared to no LED use) of electricity.
Why Choose ENERGY SAVING LED Lighting?
LED light bulbs helps you save money on your electricity bills
In a home or residential setting, this difference in lifespan and efficiency between incandescent lighting and LED lighting helps you to significantly reduce your electricity bill. In conclusion, a LED light bulb is therefore almost 50 times more efficient in lifespan, and ca. 70-80% more energy-efficient than a conventional incandescent option.
LED light bulbs have a longer life span
Instead of having to replace conventional light bulbs regularly and thereby generating high maintenance costs especially in a large-scale urban municipality setting, LED light bulbs with their exceptional long life time expectancy lead to significant cost-savings in regards to maintenance and replacement workloads.
LED lights are non-toxic and greener than other alternatives
LEDs, in contrast to CFLs, do not contain the highly toxic mercury, which is harmful not only to the environment but also to your personal health. LED lights are free of toxic materials and are 100% recyclable. Most important for issues regarding global warming and environmental change, LED light bulbs release substantially less CO2, sulfur oxide and nuclear waste. Where 30 incandescent light bulbs release about 2500 kg's of these emissions a year, LEDs only produce about 200 kg's annually.
LED lighting is flexible in color and design
LEDs can be dimmed and both light, color and distribution can be dynamic controlled and adjusted either via timers or also remote and even via the internet or your home WLAN. A well-designed LED illumination system can achieve some amazing lighting effects that influence not only the eye but also for the mood and the mind of human beings.
FEATURES OF LED LIGHTS
Brightness is equal to or greater than existing lighting technologies
Light output remains constant over time
Excellent color quality
Efficiency is as good as or better than fluorescent lighting
Light comes on instantly
No flicker
No off-state power draw
‘It is high time to start saving money, benefit from longer-lasting lighting systems and sustainable illumination - and most importantly, you can also do your part and start to help saving our planet’
