Conclusion & Comparisons
Power Consumption Summary
• Efficient power consumption
• $26.08 in annual cost for typical family
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.
| Setting | Average Watts | Cost per Year |
| Backlight 6 | 133.53 | $26.08 |
| Backlight 10 | 194.1 | $37.90 |
| Backlight 0 | 74.53 | $14.55 |
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.

Samsung UN32D5500 LED LCD HDTV Review
The D5500 has a rather high MSRP of $699, considering it’s only a 32-inch TV. There are some “premiums upgrades,” a term we use with some dubiousness, knowing that these features can be far less valuable than they appear. Nevertheless, at its core this is a good television. If you can find it a significantly reduced price it would make a great addition to a home theater. Read More...
