" From: "Darrick Burch" <[email protected]> " " I wonder if there is a significant difference in power consumption between " a linear and switching cell phone charger. considering how little they draw to begin with, i'd guess not. enough for a night light? maybe. " I read an article once stating " that a TV uses 85W (!) on standby. They didn't specify how old of a TV or " what technology (LCD, CRT, etc.) might pull current like that, but that " seemed awfully high to me. it might be either a big honking projection set or an old, pre-energystar model. long ago it was discovered that if you kept the picture tube filament on half power all the time it 1. went to full power very quickly - 'instant on' 2. lasted longer, without the full power-on surge and thermal shock - the phenomonon that makes incandescent bulbs blow when you turn them on. i don't know how much power a tube filament draws but i expect that even on half power it's nothing near 85w. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen [email protected] and think what none thought
