I've used this projector for two months. 2000 ANSI lumens? Come on! This projector is not nearly as bright as an Epson ultra portable I used to used up until a year ago. That one was rated 1200 ANSI lumens and you had no problem using it with full room lights. Not so the LP500. And we've already encountered reliability problems. This past weekend it dropped the red channel completely on the VGA input. Had to switch to S-Video cable. And through both inputs it ran at about half of the normal brightness.
