Power Consumption*(8.92)*


One of the touted benefits of LED backlit televisions is lower power consumption, and the Samsung UN46B7100 would seem to deliver in this area. To test power consumption we adjust the backlight to get the brightness level as close to 200cd/m2 as possible. In the case of the Samsung UN46B7100 this was achieved by putting the backlight at a setting of 5. We the run a standard video and check to see how much power is being draw at 2, 4 and 6 minutes. You can see our results below.

Setting Average Watts Cost per Year
Backlight: 0 72.6 $14.18
Backlight: 4 110.9  $21.65
Backlight: 10 157.9  $30.84

The Samsung UN46B7100 turned out to draw an average of 106.73 Watts at a backlight level of 5, which is above average for all HDTVs and is the best score put up by a television 46-inches or larger that we have reviewed. You can see below that the UN46B7100 beat out all three of our comparison HDTVs. The outlier is our Plasma model, which tend to be power hogs.
