Power Consumption*(8.50)*


The Sharp LC-40E67UN sucked down a reasonable amount of juice, but not an extortionate amount. We found that at our standard brightness level (which involved putting the backlight to +13), it consumed an average of around 153.5 watts. This means that if you were to run this TV for an average of about 5 hours a day, it would use around $30 of electricity over the year. Because this display wasn't capable of running at the higher screen brightnesses that many displays are capable of, the price for running it at the maximum brightness is not much higher: about $34.73. If you prefer to live in darkness, the price to run it with the backlight at minimum (-16) fell to $12.24 a year.

Setting Average Watts Cost per Year
Standard (Backlight +13) 153.5 $29.97
Maximum (Backlight +16) 177.8 $34.73
Minimum (backlight -16) 62.7 $12.24

So we can compare TVs, we set the backlight for our standard setting so that an area of white on the screen measures about 200 cd/m2. The figures below are for this standard setting across our comparison displays. One thing to note here: the LC-40E67UN does offer a number of power saving modes, which work by reducing the brightness of the backlight: the standard power saving mode reduces it to 80% of the maximum, while the advanced mode reduces it to 70%. We tested with all of these disabled.
