Power Consumption (8.92)

The initial purchase price isn't the only cash you'll have to fork over for your TV. Televisions use a lot of power while they're in use, giving them a yearly cost. We measure power consumption at three levels of backlight intensity and, of course, with our calibrated settings. With different calibrations, your average wattage (and, as a result, cost per year) might vary.

If you're using the 32LG40 with a maximum backlight brightness and our calibration settings, it'll cost you about $22.90 per year. This is about half the average cost we've seen so far. If you turn down the backlight to 200 candelas per square meter (cd/m²), which is an ideal brightness in most cases, the 32LG40 will run you a slightly cheaper $21.53. If you turn off the backlight entirely, your cost will plummet down to $9.90/year. The downside, however, is that the TV costs money even while it's turned off. Fortunately, that cost is a meager $0.45/year.
