'LED monitor' is normally meant as 'LED backlit LCD'. It is or at least was possible to buy LED only displays.

12watts is a little low, its only a little IMO. Then again, if its in low brightness mode and displaying slowly, it could be right.
22-35 watts would probably be 'worst case scenario' power consumption (brightness 100% with high frame/refresh rates). Real world power consumption would be lower.

Both led and lcd use the same screen but back light it differently.

I have never seen any test where a LED is equaled by an LCD. Most of the tests I've seen have the LED running at half the power consutmpion of the LCD.
Bad test, but the only one I sem to be able to find now.
Samsung SyncMaster 2493HM (LCD) 77 watts.
Dell U2412M (LED) 27 watts.

Both 1920x1200 24'' monitors.
This is also well worth a look even though its CRTs vs various aged LCDs with only one LED in the test.
