We use artificial lights every day and all these lights obviously consume power. LED (Light Emitting Diodes) are the latest and most advanced lighting technology today – and they have become affordable too. LED bulbs are the same mini indicator lights you see on your TV power on-off indicator, in the charging indicators on phones, laptops and every other device. In fact, traffic signals are LEDs too!

You might have already replaced your old incandescent bulbs (the traditional warm white with glowing filament) with efficient CFLs (Compact Florescent Lamps) by now. CFLs, which were popular for more than a decade now, are definitely an improvement over traditional bulbs. A 25 watts CFL produces the same light as a 100 watts incandescent bulb, and lasts six to ten times longer. Now, a 14 watts LED can produce the same light and lasts 25 to 50 times longer. Not just that, they are safer for the environment, unlike CFLs which contain toxic mercury.

Why LEDs?

1. Lower Power Consumption – A 14W LED bulb = 25W CFL = 100W.

2. Loooooong Life – Most LED bulbs have an average life span of 25,000 to 60,000 hours. In comparison, a CFL lasts 6,000 hours, an efficient T5 tubelight lasts 15,000 hours and an incandescent bulb lasts 1000 hours only. On an average, a single LED bulb can last around seven years or more, depending on usage.

If we do the math, a 50,000 hours rated LED bulb used for four hours a day can last for 34 years!!! Imagine not having to change or buy a bulb for all those years – and the money you save. There is a good chance that the LED bulb you buy will be replaced by your children one day.  Having said that, please note that while LEDs are extremely durable (have you ever seen the power light on any TV go kaput?), the drivers attached to them may not be that long lasting. A good brand however will have a high quality driver.

3. Environment Friendly – Unlike CFLs, there is no mercury or other hazardous chemical in a LED bulb. Mercury in fluorescent lamps is dangerous for aquatic life and humans too, hence LED bulbs are also a better recycling product.

4. Durable And Safe – LEDs are solid state semiconductors and have no filament or gas in them, making them much more resistant to shocks and temperatures. LEDs are cold lights, they emit very little heat and hence are safe to touch and handle. Low heat is also good for air conditioned spaces as it doesn’t increase the heat load. Most LED bulbs in India come with a warranty of one to three years. In some parts of the world, five to eight years’ warranties are also given.

5. Colors – LEDs are futuristic, they come in all colours and there are multi colored ones too. Philips has a LED bulb that can change from warm white to cool daylight.

6. Comes In All Shapes And Sizes – From 0.5W night lamp to 20W bulbs to 100s of watts composite commercial lights, LEDs are now available in most shapes and sizes. LED tubelights that can directly replace your older florescent tubes are also available.

7. Cost – LEDs have traditionally been more expensive than other lights. But recently the Indian Government has launched a scheme called UJALA where you can buy a 9W LED bulb for just INR 85. This is less than half the market price. Even with market prices of INR 200 to 300, you can easily recover the money in a year’s time from power savings and not having to replace it soon. One LED bulb can help you save around INR 500 per year depending on usage.

8. Glare – This is one disadvantage of some LED lights. If there is no good diffuser, particularly for bigger LEDs, you might get a glare if you look directly. Placing them away from line of sight or using fixtures can help you to avoid the glare.

Popular LED bulb brands in India are Philips, Syska, Havells, Wipro, Crompton, Ever-ready, Bajaj and many more. They are available at your nearest electrical shop and even on most e-commerce stores. If it makes sense, replace all your lights with LEDs today, they are worth it.
