Power Consumption (8.7)

To test power consumption we adjust an HDTV to give off 200 cd/m2, with an LCD this is done by adjusting the backlight. We then run through a standard video with the volume at zero to see how much power is drawn by the HDTV. The Samsung LN40B650 did very well in this test, drawing an average of 133.54 watts under these conditions. For an average U.S. family that works out to $26.08 in power costs each year. Below you can see all of our results, including the power draw with the backlight turned up to maximum and down to the minimum.

Below you can see how the Samsung LN40B650 performed compared to other HDTVs. You can see that it it drew a bit more power than the other two LCD televisions, but significantly less than the Plasma HDTV, which is what we expect to see. Overall the LN40B650's power consumption was below average.
