Formats & MediaNext: Page 13
Conclusion & Comparisons
Power Consumption Summary
• Annual cost of $24.75
• Less expensive to operate than the average television
• More efficient than even some smaller HDTVs
Power Consumption (8.76)
When checking for power consumption we adjust the backlight of the television until we get a peak brightness of 200 candelas per meter squared (cd/m2). At this setting the JVC LT-42P300 used an average of 125.33 watts, which works out to an annual cost of $24.75. This is for five hours of television viewing a day using the national average for energy cost. We should also note that unlike most HDTVs the LT-42P300 also draws a trickle of power when the television is turned off, although this didn't make a huge difference in the final cost. We als ran our testing with the backlight turned up to maximum and down to minimum. You can see all of our results in the table below.
| Setting | Average Watts | Cost per Year |
| Backlight 57 | 125.33 | $24.75 |
| Backlight 100 | 186.2 | $36.63 |
| Backlight 0 | 93.95 | $18.62 |
The JVC LT-42P300's power consumption is significantly above average for all televisions, and is as good as or better than even smaller HDTVs, as you can see below.

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...
