LED Bulbs Benefits: Why India Needs this Technology to Flourish?

LED technology improved rapidly lately. LED (light emitting diode) is a semiconductor diode that emits light. It features solid state technology. Due to energy saving, eco friendly and long lifespan, it’s regarded later on as truly one of the most famous light sources.

In 2009, 80-100 lm/w LED is used as light source for lighting. LED lightbulbs were considered by many individuals as replacement of incandescent lightbulbs. What are advantages?

1. Energy Saving

Now, efficacy can be about 80lm/w. It’s 8 times than efficacy of incandescent lightbulbs. It saves over 80% energy.

Comparing with CFL bulbs, in addition, it saves about 30%-40% energy.

2. Ecofriendly

It will not feature UV, IR, lead or mercury. It’s eco friendly light source. For that reason, it’s an excellent option for residential light.

3. Long Lifespan

Lifespan can be 50,000 hours. It’s more than 20 times than lifespan of incandescent lightbulbs. It’s over 8 times than lifespan of incandescent lightbulbs


4. Broad Selection of Colours Option

Colours may be white, red, blue, green, yellow and so on, so colours of LED bulbs are available for all these colours also.

5. Design Flexibility

It’s a lot smaller than conventional light sources, therefore it allows for radically different illumination designs capitalizing on the unobtrusiveness of the source.

Of lessons, LED is imperfect. Two disadvantages are complete luminous flux and cost. Entire luminous flux is less than 500lm in 2009. Head sink is an issue, if luminous flux is higher. Lifespan of LED is not long if head sink is bad.

Cost of LED bulbs are a bit high. Retailing cost of 5W LED lightbulbs might be over USD 25. Nevertheless, consider price of replacing and energy into thought, LED is economic.

Over 120lm/w, efficacy of LED lightbulbs are going to be in the next 2 years. Retailing cost will likely be lower than USD 20. We consider many nations in Europe and North America can accept it.
