Introduction
The power consumption of TVs is dependent on a number of factors, including the type, settings, and of course screen size.
With regards to TV type, a factor to consider is how the screen is backlit (LED or fluorescent). Fluorescent-backlit TVs can consume far more power than LED-backlit models (not to be confused with OLED) due to the fact that LEDs are more energy-efficient.
Modern LEDs easily exceed efficiency ratings over 100 lumens/Watt, with some crossing the 200 lumen/Watt mark such as the Samsung
