Vs Samsung UN46B8500
Power Consumption Summary
• Costs about $32 a year to run at our standard brightness.
• At maximum backlight setting, that rises to $40.
• Has some power consumption settings that don't do much.
Power Consumption (8.42)
The Sharp LC-46SB57UN sucked down a reasonable amount of juice, but not an extortionate amount. We found that at our standard brightness level (which involved putting the backlight to +5), it consumed an average of around 162.17 watts. This means that if you were to run this TV for an average of about 5 hours a day, it would use around $32 of electricity over the year. Because this display wasn't capable of running at the higher screen brightnesses that many displays are capable of, the price for running it at the maximum brightness is not much higher: about $40. If you prefer to live in darkness, the price to run it with the backlight at minimum (-16) fell to $15 a year.
| Setting | Average Watts | Cost per Year |
| Backlight: -16 | 74.67 |
$14.58 |
| Backlight: 5 | 162.17 | $31.67 |
| Backlight: 16 | 200.00 | $39.06 |
So we can compare TVs, we set the backlight for our standard setting so that an area of white on the screen measures about 200 cd/m2. The figures below are for this standard setting across our comparison displays.

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...
