JVC LT-32P679 LCD HDTV Review - Power Consumption

Power Consumption (8.85)
To test power consumption we adjusted the JVC LT-32P679's back light to produce a light level of 200 candelas per meter square (cd/m2), which is a reasonable level for both bright and darker situations. We then test how much power is used over six minutes watching a standard TV show. We also look at power consumption when the backlight is turned up to maximum and when it it turned down to minimum.

The JVC LT-32P679's power consumption at 200 cd/m2 was $23.08 over the course of a year for the average American family. This is a reasonable amount for power for an HDTV this size, it's significantly less than what you'd see from a larger HDTV. We also look at power consumption with the backlight turned up to maximum, which in the case of the JVC LT-32P679 means moving from the calibrated level of 98 to 100. The difference is not significant, as you would expect so go ahead and crank that sucker up. You can save almost $15 per year by turning down the backlight to 0, but this makes the HDTV so dim that it's not worth watching.
