Just checked the back of my 37" Vizio TV/computer display and it says
120V, 3.2A. That would be almost 400W. But I suspect it could be
under 100W if they cared, and used LED back light. Just a SWAG there
but, if true, that would be a significant savings for someone like me
that has used almost all spiral bulbs for 6-8 years.
I can light up the room brightly burning only about 20W of spiral bulbs,
and even less with LED bulbs. TV and computer display power is
significant even if we aren't using CRT's anymore. Don't discount it.
