Though the nomenclature differs, a LED TV is essentially a LCD in itself. The actual name for a LED TV is A LED backlit LCD TV.
Both the forms of television sets make use of LCD - the Liquid Crystal Display panels to decide the position of light on your screen. Now you may wonder what is the difference actually when both of them use same display panels.
The difference lies in the back lighting. Regular LCDs have cold cathode fluorescent lamps, commonly known as CCFL while LED TV uses smaller LEDs - the Light Emitting Diodes.
Advantages of LED TV
1. Since the LEDs used for back lighting are smaller, the size of your gets thinner. Most of the popular LEDs today are almost 1 inch thin.
2. LEDs - as we are well aware of - consume less energy. So, LED TV would be a better option in terms of consumption of electricity.
3. Picture quality is enhanced in LED TVs in comparison to the ordinary LVDs. That would be because of the selective dimming used in LEDs.
4. LED TVs offer better RGB contrast. That would mean you would get a real life like picture performance.
5. Since LEDs are known to last longer and efficient in their performance, you can expect a longer life span compared to LCDs.
But, by providing you all these benefits, the LED TVs are not economical. They are easy to mount, less power hungry and offer you a great picture clarity, and all this comes with an elevated cost. If you are low on budget, a Plasma TV can be a better choice. But do remember that they are bulky and consume more power.

In terms of power consumption, LED (LED backlit LCD) TVs are being projected better and efficient by the sales and marketing for quite some time now. However there are lot of things that are not coming to the consumers with proper fact. So let's take a look at things how the LED and LCD TVs fare based on the electric consumption.
Energy Consumption: Pure LCD TVs are known to consume less energy compared to the plasma TVs. However in case of the LED and OLED TVs you'd find that LCD are consuming a bit more. There are two variations in LEDs- LED backlit LCD and OLED. OLED screens also known as organic LED screens known to consume less power that regular LEDs. Also they are a bit cheaper. As per tests they are known to die off pretty quickly compared to the regular LCD & LED. In case of LED (LED backlit LCD) panels it has following subtypes such as - Edge-LED, Dynamic RGB & Full array. Those are thinner and consume less power than LCD as well. There is also variation in EDGE LED known as CCFL backlight which also known to consume less power than the regular LCD.
Eye Strain: Screen's refresh rate and the light emitted and the room ambiance decides which screen affects the more to eyes. You have to also test the TV screen with your own eyes. The reason being CCFL LED has been known to be good for some of the people. However people with specific lens on their eyes, may not find CCFL LED TV good for their eyes. LCD on the hand being consistent with it's refresh rate calibrated doesn't have much eye strain issue for normal eyes. However you'd find that EDGE LED's known to have less strain than the normal LCD screens.
As far as the eye strain goes, don't go with the TV test results and internet opinion, instead trust your eyes. They can tell the difference between minute flicker and strain of the screen. So you'd not enjoy those 52'' plasma screen of Samsung Smart TV because in dim light those are going to strain your eyes.
