The Optoma PK301 projector’s brightness is at least as compelling as the 3M MPro150’s integrated software suite. Road warriors never know what type of environment they’ll be making their pitch in, and the PK301 is much more forgiving of poor lighting conditions. It’s capable of producing 50 ANSI lumens while running on AC power, and drops to 20 lumens—a level equivalent to 3M’s projector—while running on battery power.
