They where Heavvvy, plus put out lots of heat. My Samsung 3D 51" ate up like 230 watts.\n\n\nThat's the big kicker for me in my office. If I shut the doors to watch something or play a game for a few hours, it gets warm and toasty in there pretty quick. Mine is up there at 585w for a 65". That's a lot of heat. Nice in what we call winter where I live, but I won't miss it when it's gone because of that heat.
