Resolved Question

PN51D8000 Power Consumption

Nov 27, 2011 11:39AM PST

I am very interested in this plasma TV based on the CNET review. However, I read that, in spite of the Engery Star rating, the TV consumes a considerable amount of power.

I read the information about power consumption on CNET and understand that plasma screens use more ebergy than LCDs and LEDs, but the annula cost doesn't seem prohibitive for plasmas.

Now I am not greenie. I just don't want something that is going to cost me a lot of money to watch. Can anyone comment on this issue?

", the screen consumes an average
of 185 watts, while the blown-out Dynamic mode eats up a whopping 335
watts. Only the HDTV's screen-darkening Standard mode merits the
EnergyStar logo, and even that consumes an average of 105 watts. It's
not an energy hog like the PN51D550 (which ate up 281 watts on average)" http://www.pcmag.com/article2/0,2817,2390455,00.asp

Plasmas tend to chew more Watts. They have to do this since you are sending light in some 175 degrees. Compared to LCD, the viewing angles are monstrous and it takes Watts to do that.

We have to do a little math.

Here, ONE KILOWATT HOUR is 14 cents. This varies across the world but I'll use it.

We also see the Watts vary depending on the settings. So let's figure out ONE HOUR of viewing cost at low and high wattages.

185 Watts = 2.59 Cents per hour
335 Watts = 4.69 Cents per hour

Hope this helps.
