I know CRTs start to bloom after 30.0 footlamberts so that's probably the maximum they can do, how do LCDs do?
I find 30 fL-35 fL "just right" for viewing in a DARK room (I have no idea what is meant by 'medium light-controlled room'). Turn on even 1 lamp and you may find yourself wanting more luminance. With sunlight coming in a window or two, you'll want all the luminance you can get.
There are some LCDs that cannot be "turned down" to get luminance as low as 30-35 fL... that would piss me off. If the minimum luminance level you could set was, say 45 fL... that is annoyingly bright when there are no lights on in the room (measurements taken with a Konica-Minolta CS-200 meter which is quite accurate for this type of measurement).
Of course, all of these measurements should be taken with a 100% white window to get a reasonable representation of the peak white level you will see in actual video content (though it won't matter for the LCD, may as well be consistent).
