2D and 3D televisions as well as smart televisions all share the same display technology. Energy efficiency is affected by the method of screen illumination and by the image processing that is performed in every television.
The use of 3D or smart technologies makes little difference to the overall energy consumption. For energy improvements, more efficient illumination will play an important role as will smaller integrated circuit sizes in future televisions. Neither of these factors change between 2D, 3D and smart televisions.
LED lights are so much efficient when compared to other types of lights. They use light emitting diodes which are not only durable but also use up less energy thus reducing on the overall consumption.
When compared to a plasma, no. Plasma tv's use much more energy. However, LED technology is the most cost efficient.
In general an LED consumes less energy than a Plasma.
LED light fixtures are made out of clusters of very small, super energy efficient bulbs. Because many of those bulbs are used, LED lights can be built to mimic the effects of regular incandescent bulbs. A huge part of what makes LED bulbs so energy efficient is that they do not produce heat as incandescent light bulbs do.
They do use about a quarter of the energy as normal bulbs.
A table lamp with a fluorescent or LED bulb provides excellent energy efficient lighting. Almost any lamp can accommodate a compact fluorescent or LED bulb which makes any fixture more efficient.
energy efficient weigh less than tube TVs
It is an LED bulb.
Led (light emiting diode)
Light bulbs in order of the least to most energy efficient : incandescent, halogen, fluorescent, LED. For home owners, most reasonable is the CFL lightbulb, which is cheaper and longer lasting than the LED.
The best energy efficient lights are LED lights. They are very small and use very little electricity, but they are brighter then most conventional lights.
LEDs are definitely better than the ordinary light bulbs because they're more energy efficient, and you'll be able to get a lot of savings since you don't need to change your bulbs every now and then.
