LED TV's

I have read that LED screens can use up to 50% less power than LCD.

LCD should use less energy, but there is alot of new technology out thee, i would do some research on the size of tv you want and go from there. As you know the nicer power conserving tv are going to be a little bit more pricey.

I read that even though LCD supposedly should use less energy, the big screens somehow consume more because of its size. Don't know how true this is thought but I've read a number of reports about this. Is it true?

I switched my monitor to LED 14" long ago, and more recently my CRT 19" TV with an LED 26". The old TV used 300 watts and the new one uses 85 watts(and bigger HD picture!). The old CRT monitor used 250 watts and the 14" LED uses 32 watts. Meaning a substantial power savings. Shopping around and buying on Ubid saved a bundle. I also changed to an Energy Star computer, and everything is on surge shutoff strips so no dead loads.
The huge screens are a waste of power and money. Do you really need it? No, it is a greedy want, and NOT green. Just get what you need and not what you may want that is oversize. Part of going green is a little sacrifice for our biosphere, and future generations.

LCD TVs using edge-lit LCDs can be ultra-thin, because the LED sources are on the side. Edge-lit LED-lit LCDs are also less expensive than LCD TVs using LED backlit technology.

On the other hand, LCD TVs that use LEDs across the rear of the display can create sharply deeper blacks, through a technique called “local dimming.” When a scene calls for a dark image, the LEDs in that area can be shut off completely, so no light leaks through what should look black.

The LED TV and Monitor did cost almost double a cheapo CRT of the same size, but the much lower power use means the LEDs are used a little more while still saving a bundle of power. When you want to go green, or just save money in the long run, go LED!!!!

And, this Christmas, we got rid of our 50 watt string of little bulbs for our 4' artificial tree and replaced them with an LED colored rope light of only 6 watts. Now we can keep the tree lit up much more with little draw from our L-16 battery banks charged by the sun.

Was just wondering this myself the other day. Thanks for the insight guys for you all have steered me in the right direction for my next tv purchase.

while LED's are more energy efficient, you'll most likely not be able to recoup the cost vs an LCD tv. Obviously, models vary on energy consumption and LED prices are coming down etc. but you have to keep in mind that even if an LED is 50% less than an LCD you still need to understand how much is 50%. Meaning, an LCD might cost ~$20/month to run, so therefore an LED could be ~$10/month, saving you $10/month or $120/year so payback could be in like 9 years.
Just like they've been telling us for years to read our food labels, read the energy labels on electronics as it'll tell you how many kwh that device uses.

We gave our LCD 26" TV to our son and got an LED 32" which uses the same electricity(85 watts) for less($300) than we originally paid for the LCD($400). Unfortunately I had to change to a 16" LCD monitor when the 14" LED went out. It uses over 40 watts versus the 32 of the LED, but was the smallest and cheapest they had($99). Being on totally solar power makes you think of which uses the least power and the bang for the buck. The smallest LED monitor was 17" for $168, and only used a few watts less power.
Of course the huge plasma TVs are costly energy hogs for greedy people who don't care about the environment, and there are far too may of those. Few people really think in the long term, unfortunately, so they are still selling the 20" $100 CRT TVs which use 300 watts. Short term thinking and the effects of lower wages of overpopulation.

actaully the newer plasmas aren't that much worse than lcd's/LED's and are even energy star compliant.
based on the engery guide labels, a 51" samsung plasma run for 5 hours a day, costs $23/year to operate whereas a 55" LED is $17/year, whereas a 46" LCD costs $31/month.

I know it's not a perfect comparison, but it gives you an idea that things are constantly changing and preconceptions that were true a few years ago, may not be the same today. So from these labels, the LCD people are the greedy

So the moral of the story, read the label, even if you read them last year

Maybe some LED TVs are overpriced, but the most expensive ones and the biggest energy users besides CRTs were the big plasma TVs. Next were the big LCDs followed by the LEDs. This was from recent shopping.

I got rid of my plasma when I went solar and use a 19" LCD, 35 watts when running. LED TV's are diminishing returns even for a solar home. Kind of like switching CFL's for LED bulbs... However, doing the switch before going solar will help save on solar panels needed.....
