Panasonic TC-37LZ85 LCD HDTV Review - Power Consumption

Power Consumption (9.06)
Using our calibrated settings but turning down the backlight to a level of 37, which works out to a brightness of 200 candela per meter squared, we measured the Panasonic TC-37LZ85's power consumption at an average of 95.5 watts. We use a brightness level of 200 candelas per meter squared because this should be a good level for viewing both in a brightly lit room and a dark room. Using 95.5 watts works out to an annual cost of $18.72, which is pretty power efficient. Below you can see what happens when you turn the backlight up to maximum or down to the minumum. One interesting thing to note is that at maximum backlight the Panasonic TC-37LZ85 only costs about $5 more per year to operate than the average calibrated cost for all TVs we've reviewed, further pointing out how efficient it is.
