Not bad for 13 watts.

Here the projector is displaying in Bright mode (13 watts on a fully charged battery) onto a beige wall. The lab is no where near completely dark, the blinds on the windows are leaking in some light and the door is leaking a lot of light through the window in the door.
The width of the projection is perhaps a little over 5 feet wide. I was limited by the width of the room how far away from the wall i could easily set up.
