    OK, I was under the impression that LED's used less power than LCD's (which are fluorescent).

    Now I was looking around at some TV's and check this out:

    LG 42" 1080p 60Hz LCD HDTV 42LK450 - 175W
    LG 42" 1080p 60Hz LED-LCD HDTV 42LV3700 - 55W

    LG 42" 1080p 120Hz LCD HDTV 42LK520 - 90W
    LG 42" 1080p 120Hz LED-LCD HDTV 42LV5500 - 125W

    Now what puzzles me is that not only is the "LCD vs. LED power usage" inconsistent (same brands even), but in the 60Hz LCD case, the power consumption seems to be nearly double the 120Hz model!
