Right. But I have a back-lit led 55" TV and it is nice and cool (90W) ... too bad there's no 30" with the high resolution.
I'd like a second NEC3090 ... but it just pumps out so much heat in the summer!!
There was at least one at NewEgg at one time, but I am not a fan of Samsung LCDs at all:

It's still available online elsewhere, but almost $4K new! Geez. About the same wattage as the NEC, no point, except that it probably has a better black than the NEC.
The two modern CCFL based 23" IPS and PVA models both use about 25 Watts of power at half brightness. Current advances in power efficiency are partly both changes in backlight but also advances in the LCD technology itself.
CCFL actually has more natural precise colors compared to LED. I would say manufacturers should skip LED and go right into OLED backlit, if they want to do it right.
OLEDs do not use a backlight.
