Our contemporary LED bulbs use 90% less energy than standard light bulbs and are tested and manufactured standards to ensure that they are safe and efficient, helping to lower the energy required to power them and reducing your carbon emission .LED converts up to 80% energy into light. Changing your incandescent light bulbs to new, efficient and environmentally friendly LED light bulbs is one of the easiest ways in which you can reduce carbon emissions. Reduce the Wattage you’re using in your lighting and you can vastly reduce the energy you use in your home. Our 4 Watt LED bulbs produce the illumination equivalent of a 40 Watt incandescent bulb and unlike first generation LED bulbs, their impressively lower Wattage no longer means reduced brightness. In fact, you’ll enjoy the energy and cost savings as well.

All incandescent and fluorescent lights produce light that flows in all directions, wasting light as well as heat. CFL bulbs may be energy efficient, but they are not environmentally friendly. On the other hand, new technology in the form of LED lamps that can directly replace both incandescent and CFL bulbs is both highly efficient and environmentally friendly . Fluorescent Lighting contains mercury, a harmful toxin, LEDs do not. This makes LEDs safer to use and dispose of at the end of their life. LEDs are diodes that convert energy directly into light through the movement of electrons in the semi-conductor material. This means that they lose far less energy to heat than other light technologies – they are up to 85% more efficient than filament bulbs, and even around 5% more efficient than CFLs.

Many energy efficiency measures are low cost and even save money. LED could indeed become in a near future a replacement for fluorescent tubes . Additional benefits exist for areas that use air conditioning. As the power consumed is reduces due to the lower heat emitted from LED lighting. This also extends the life of the air conditioning unit because it is not worked so hard. LED’s tubes have specific thermal and electrical needs; this work is focused therefore on optimization studies in terms of association topologies: serial versus parallel. The starting point is electrical equivalent models extracted from single LED.

Generally high-quality LEDs can reach a durability of 100,000 hours without any problems, if the user operates them in a proper manner. Proper manner means that the values stated by the manufacturer concerning current and temperature are kept. However, external circumstances like humidity or weather conditions if the LEDs are operated outdoors, may influence the life expectancy of an LED. LED do not contain a filament that can be damaged by shock and vibration- making LED one of the most stable light sources available.

LEDs produce 100% light instantly, with none of the warm up time required by fluorescents. Plus, they are free of visible Flicker-ideal to help prevent discomfort associated with traditional lighting. LED light strip and hooked it up to the battery with a voltage knob making it a DC based flicker free LED light.

LED system manufacturers can design and build long-lasting systems. The life of LED is between 4 and 40 times greater than traditional products. What’s more, they produce consistent light output over their entire life. In this study, several white LEDs from the same manufacturer were. Method to rapidly estimate life by data extrapolation. The life of these LEDs decreases in an exponential manner with increasing temperature.

The true cost of a traditional lighting source is not only in its energy consumption. There is also maintainance over its life-time, replacement labour, lamp outlay and disposal costs. With LED, these costs don’t exist. LED is a fit-&-forget solution. Costs of LED lighting products do vary widely with good-quality LED products carrying a cost premium when compared with lower quality, inferior designs. Nevertheless, over recent years production costs of LED devices has declined rapidly, primarily as a result of the adoption of LED technology in the production of HD TV

Certainly, LEDs also provide a green alternative at the end of their life as they contain no harmful chemicals. The mercury contained in just one fluorescent lamp 30,000 litres of water beyond safe drinking level limits. But there is a big problem with CFL bulbs: they contain mercury, which is definitely not good for the environment or human health. Exposure to mercury can cause developmental problems in unborn children.


An incandescent light bulb is considered an extremely inefficient form of lighting, reason being, just 2-5% of the electricity input is converted into light which is visible to human eye. Rest of the energy is lost in the form of heat and thus, results in more electricity usage and comparatively less output. CFL (Compact Fluorescent Lamp) betters an ordinary bulb in terms of efficiency but brings completely different side-effects along with it. Each CFL contains about 5mg of mercury, a toxic substance in it which makes it hard to dispose them.

LEDs (Light Emitting Diode) have come as a respite to both these problems of efficiency as well as harmful chemicals. LEDs consume only one-tenth of the energy used by an ordinary bulb to provide the same or better light output. The only barrier in the adoption of LEDs is its high cost. Even after being such an efficient lighting system, people have been sceptical of using LEDs because of the high investment involved until now.

After understanding the thought process of the people of India and our country’s current power needs, the Government of India came up with a scheme named “UJALA”- an acronym for “Unnat Jyoti by Affordable LEDs for All”. Unnat Jyoti by Affordable LEDs for All (UJALA) was launched by Prime Minister of India Narendra Modi on 1 May 2015. The scheme is being brought to execution by Energy Efficiency Services Limited (EESL). A joint venture of NTPC, Power Finance Corp, Rural Electrification Corp and POWERGRID, the EESL was set up under Power Ministry to facilitate implementation of energy efficiency projects. The government will purchase the bulbs from the Energy Efficient Services Ltd (EESL) kiosks.

The main objectives of UJALA are to promote efficient lighting in the form of LEDs, spread awareness on using this efficient form of lighting and to help preserve the environment.

Following are the important points one needs to keep in mind before approaching to purchase these LEDs-
• Under the scheme, people will get these energy efficient 9W, 900lumens LED bulbs at an upfront payment of just ₹80-85 when they actually cost around ₹300 in the market. The same will be available to commercial bodies at a cost of just ₹90.
• Each household will get a maximum of 10 bulbs in the first phase.
• Consumers can purchase these affordable LEDs by presenting either their electricity bill or any other Identity card.
• The distribution of these LEDs will take place through DISCOM offices, DISCOM bill collection centers, designated EESL kiosks, weekly Haat markets, etc.
• The bulb comes with a three year replacement warranty if any case of technical defects occur.
• Each 9W LED bulb gives the same luminosity as compared to a 100 W incandescent lamp, while consuming less than one tenth of power.
The distribution of the bulbs has already started in most of the states with Andhra Pradesh topping the list with the distribution of around 1.9 crore bulbs as of 1st June 2016.
As of 1st June 2016, a total of 11 crore LED Bulbs have been distributed under the scheme. This led to a savings of 39.4 GWh per day in energy and ₹15.76 crore per day in cost and a per day reduction of 31,917 t of CO2. Within 1 year of its launch, 9 crore LED bulbs have been sold in the country, reducing our electricity bills by ₹55 billion.

In the upcoming fiscal year, the government is planning to procure 20 crore more LED bulbs through auctions. The procurement cost of LED bulbs has now fallen as low as to ₹54.90 per unit from ₹64.41, which has enabled the government to further reduce the retail price to ₹75 per piece. With the procurement of these 20 crore LED bulbs this fiscal year, the price now can come down to ₹44 per unit.

UJALA scheme will not only help reduce consumers’ electricity bill but also contribute to the energy security of India.

To a better, greener and brighter future!


‘Smart city’ simply means different things to varied number of people as per their requirement. A smart city would have a different connotation in India than, say, Europe. Even in India, there can be no one way of defining a smart city.

The core infrastructure elements in a smart city would include:
i. Adequate water supply,
ii. Adequate electricity supply,
iii. Solid waste disposal,
iv. All areas connectivity to transportation,
v. Housing for all class of people.
vi. Proper Industry setup and IT resource
vii. e-Governance and citizen participation in it,
viii. Sustainable environment,
ix. Safety and security of people,
x. Health and Education

In the process of the Smart Cities Mission, the objective is to promote cities that provide all above mentioned points to its citizens, a clean and sustainable environment and application of ‘Smart’ Solutions. The focus is on sustainable and inclusive development and the idea is to look at all possible areas to create a standard model which will act like a reference guide other upcoming cities.

Smart Cities are cities with a long-term efficient process of designing a city into well planned model of sustainable, and livable criteria through application of best possible technologies. India has focused on a major initiative to save energy by becoming efficient. The Smart cities are expected to install the LED lighting products in its most of the projects.

Now smart cities in India is all set to become the most-populous country in the world by 2030, making it the biggest and the most growing market for global manufacturers and service providers. Prime Minister Narendra Modi’s vision “Digital India,” has set an ambitious plan to build 100 smart cities. With the tag line “ATIKRAMAN” India’s Smart City plan is set out on its work.
