Good idea. This is what I found.
http://www.projectorcentral.com/pdf/..._spec_3880.pdf
The document says "290 W (Approx. 0.08 W in standby mode with fan stopped)".
Now that sounds pretty good to me. On the other hand, if someone has one of these tools and a projector I'd be interested in comparing empirical evidence to manufacturers published specs too.
