I don't know.  I have a front projector and with 200W it illuminates 
 >4000 sq. inches very nicely.  :-)  ISTM that 1W should perform just as 
well on 20 sq inches.  Aren't LEDs more efficient than that arc lamp 
thingy in my projector?

BTW, front projection technology has really come along.  Seems like the 
best kept secret in home theater to me.  Bang for the buck is incredible 
with DLP, as long as you don't see the rainbows.  ;-)
